Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. Application No. 63/745,125, titled Interchangeable Modular Magazine Well, filed January 14, 2025, which is hereby incorporated by reference in its entirety.

FIELD OF DISCLOSURE

The present disclosure relates generally to firearm magazines. In particular, but not by way of limitation, the present disclosure relates to systems, methods and apparatuses for a modular magazine well attachment.

DESCRIPTION OF RELATED ART

Ease and speed of reloading is often a concern with firearms used in various roles such as competition, defense, military or law enforcement. For detachable box magazine-fed guns, an enlarged magazine chute flare ("magwell flare" or "magwell") can be affixed. This creates a wider funnel effect to reduce the likelihood of errors when inserting a fresh magazine, thereby speeding up the magazine insertion and overall reloading process.

While large funnels are ideal for reloading, the drawback is additional size, bulk, and potential interferences caused by adding such a component to a weapon. This is especially true in handguns where compactness is often a critical factor. While some competition-focused guns may have large integral magazine well flares incorporated into the design, most magazine wells typically replace an existing component (i.e., 1911 mainspring housing) or are bolted into place (various Glock magazine wells and similar).

Occasionally, modification to the grip is needed to allow an aftermarket magazine well to be used, but adapting or customizing a particular gun may be difficult to do in a quick and seamless manner.

There is therefore a desire in the art for a magazine well that provides optimal reloading speed and efficiency while maintaining the firearm's compactness and allowing for quick/easy customization.

DETAILED DESCRIPTION

The following description sets forth exemplary aspects of the present disclosure. It should be recognized, however, that such description is not intended as a limitation on the scope of the present disclosure. Rather, the description also encompasses combinations and modifications to those exemplary aspects described herein.

This disclosure addresses the challenges in the art by disclosing a rail interface (or slot or tab interface) between a firearm grip component and a magazine well element, thereby allowing quick interchange between different magazine wells. This improved magazine well design allows a user to quickly adjust the amount of flare of the magazine well element, and the magazine well element can be made in various sizes and styles, and using various materials. A user can thereby modify or customize the magazine well flare without changing the firearm’s grip—to more quickly modify the magazine well flare for different uses: e.g., a larger flare for competition and a minimal flare for concealed carry. The disclosed magazine well design is operable with various magazine types and aftermarket accessories and achieves a solid interface with the grip so as to withstand the impact of frequent magazine changes and potential abuse in high-stress situations (e.g., competition or combat).

The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

Preliminary note: the flowcharts and block diagrams in the following Figures illustrate the functionality and operation of possible implementations of a selector lever according to various embodiments of the present disclosure. It should be noted that, in some alternative implementations, the functions noted in each block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved.

It will be understood that, although the terms first, second, third etc. may be used herein to describe various elements, components, regions, layers and/or sections, these elements, components, regions, layers and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, layer or section from another region, layer or section. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the present disclosure.

Spatially relative terms, such as “beneath,” “below,” “lower,” “under,” “above,” “upper,” and the like, may be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as “below” or “beneath” or “under” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary terms “below” and “under” can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly. In addition, it will also be understood that when a layer is referred to as being “between” two layers, it can be the only layer between the two layers, or one or more intervening layers may also be present.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure. As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof. As used herein, the term “and/or” includes any and all combinations of one or more of the associated listed items, and may be abbreviated as “/”.

It will be understood that when an element or layer is referred to as being “on,” “connected to,” “coupled to,” or “adjacent to” another element or layer, it can be directly on, connected, coupled, or adjacent to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly connected to,” “directly coupled to,” or “immediately adjacent to” another element or layer, there are no intervening elements or layers present.

Embodiments of the disclosure are described herein with reference to cross-section illustrations that are schematic illustrations of idealized embodiments (and intermediate structures) of the disclosure. As such, variations from the shapes of the illustrations as a result, for example, of manufacturing techniques and/or tolerances, are to be expected. Thus, embodiments of the disclosure should not be construed as limited to the particular shapes of regions illustrated herein but are to include deviations in shapes that result, for example, from manufacturing. Accordingly, the regions illustrated in the figures are schematic in nature and their shapes are not intended to illustrate the actual shape of a region of a device and are not intended to limit the scope of the disclosure.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and/or the present specification and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

FIG. 1A illustrates a first embodiment of a firearm grip assembly having a rail interface enabling a sliding engagement between a firearm grip and a magazine well element. This interface allows switching of the magazine well element 104 with others having different degrees of flare, size, etc. The firearm grip 102 can include a distal end 103 adjacent to and interfacing with the magazine well element 104, and a proximal end 101 that may include a trigger guard and structures for interfacing with a frame, slide or receiver. However, in other embodiments, the proximal end 101 may couple to a lower of a long gun (e.g., a pistol-caliber carbine (PCC), a Personal Defense Weapon (PDW), machine-pistols, or a submachine gun, to name some non-limiting examples). In other embodiments, the firearm grip 102 can be unitary with a lower or other aspects of a long gun rather than being detachable therefrom. The magazine well element 104 extends from a proximal end 105 to a distal end 107 with the proximal end 105 adjacent to and interfacing with the distal end 103 of the firearm grip 102. At the distal end 107, a magazine first enters the magazine well element 104. Thus, the proximal end 105 of the magazine well element 104 may be positioned adjacent to the distal end 103 of the firearm grip 102, creating a continuous structure for guiding magazine insertion. The magazine well element 104 is flared from the proximal end 105 toward the distal end 107.

The illustrative embodiments of FIG. 1A show a cartridge traversal axis 122, which represents the direction along which cartridges traverse when a magazine feeds cartridges toward the proximal end 101 of the firearm grip 102. In various embodiments, the cartridge traversal axis 122 may be oriented at a slight angle to a longitudinal axis 124 of the firearm when the firearm is held in a firing position. The longitudinal axis 124 extends through the assembly, representing the longitudinal axis through a firearm barrel when the firearm grip 102 is attached to a firearm. The longitudinal axis 124 may be oriented substantially horizontally when the firearm is held in a firing position. In some embodiments, the cartridge traversal axis 122 can be perpendicular to the longitudinal axis 124. In other embodiments, the cartridge traversal axis 122 can be curved, but otherwise slightly angled or perpendicular to the longitudinal axis 124.

Referring to FIG. 1B, an exploded isometric view of the firearm grip assembly illustrates the relationship between the firearm grip 102 and the magazine well element 104. The firearm grip 102 includes the proximal end 101 and the distal end 103. The distal end 103 of the firearm grip 102 includes a proximal rail portion 108. In various embodiments, the proximal rail portion 108 may include one or more rail elements extending from the distal end 103 of the firearm grip 102. The proximal rail portion 108 may be configured as a male rail element that protrudes outward from the firearm grip 102 or alternatively may be configured as a female rail element that receives a corresponding male rail element.

The magazine well element 104 includes the proximal end 105 and the distal end 107. The proximal end 105 of the magazine well element 104 includes a distal rail portion 110. The distal rail portion 110 may be configured to complement the proximal rail portion 108, enabling sliding engagement between the two components. In various embodiments where the proximal rail portion 108 is configured as a male rail element, the distal rail portion 110 may be configured as a female rail element that receives the proximal rail portion 108. Alternatively, where the proximal rail portion 108 is configured as a female rail element, the distal rail portion 110 may be configured as a male rail element.

The proximal rail portion 108 and distal rail portion 110 may be configured for sliding engagement along the sliding axis 126. This sliding engagement may allow the magazine well element 104 to be attached to the firearm grip 102 by sliding the distal rail portion 110 onto the proximal rail portion 108 in a direction substantially parallel to the sliding axis 126. Similarly, the magazine well element 104 may be removed from the firearm grip 102 by sliding the distal rail portion 110 off the proximal rail portion 108 in the opposite direction.

The distal end 103 of the firearm grip 102 includes a proximal portion 108 of a rail interface and the proximal end 105 of the magazine well element 104 includes a distal portion 110 of the rail interface. The proximal and distal rail portions are shaped for sliding engagement between the magazine well element 104 and the firearm grip 102 along a sliding axis 126. The sliding axis 126 is defined as an angle extending subperpendicular to the cartridge traversal axis 122 and somewhat perpendicular to the magazine axis (or perpendicular to the cartridge traversal axis 122 where the cartridge traversal axis is perpendicular to the longitudinal axis 124). In various embodiments, the sliding axis 126 may be oriented at an angle between 70 degrees and 110 degrees relative to the cartridge traversal axis 122. In various aspects, the assembly direction of the magazine well flare may be such that it is unlikely to disassemble accidentally when pulling the magazine from the grip. Further, in some aspects, the assembly direction does not need to be perpendicular to the direction from which the magazine is pulled; in various aspects, any angle within 45 degrees of perpendicular to the cartridge traversal axis 122 may be advantageous for not accidentally disassembling the magazine well element when pulling on the magazine.

The magazine well element 104 may be configured to flare outward from the proximal end 105 toward the distal end 107, creating a funnel-like structure. This flared configuration may provide an enlarged opening at the distal end 107, facilitating faster and more reliable magazine insertion during reloading operations. The degree of flare may vary in different embodiments, e.g., to accommodate different user preferences or operational requirements. In the illustrated embodiment, the proximal portion 108 is an inner element of the rail interface and the distal portion 110 is an outer portion of the rail interface. This can be more clearly seen in the illustrative cross section shown in FIGS. 4A and 4B (e.g., see proximal portion 308 and distal portion 310). However, these orientations can be switched in other embodiments with the proximal portion being the outer portion of the rail interface and the distal portion being the inner portion of the rail interface.

A notch 119 may be positioned at a front portion of the magazine well element 104. The notch 119 may be configured to receive a corresponding detent 120 located on the firearm grip 102. In various embodiments, the detent 120 may be a protrusion extending from the firearm grip 102 that engages with the notch 119 when the magazine well element 104 is fully seated on the firearm grip 102. In various embodiments, the notch 119 includes a small flange that acts as a detent to lock into a notch in the detent 120. In some aspects, the notch 119 and detent 120 may optionally form a friction fit, snap fit, or some other type of selective fixation, which may also enhance the secure attachment of the firearm grip 102 to the magazine well element 104. The engagement between the notch 119 and detent 120 may provide additional securement of the assembly, reducing the likelihood of unintended separation during firearm operation.

The firearm grip 102 is configured to receive a magazine and to enable the magazine to feed cartridges toward the proximal end 101 of the firearm grip 102. Cartridges may traverse substantially along a cartridge traversal axis 122 that is slightly angled from orthogonal (e.g., between 60-85˚, or between 65-80˚, or 70-75˚, or substantially 72˚) to a longitudinal axis 124 of a barrel of the firearm. The magazine well element 104 can slide onto the distal rail portion 108 of the firearm grip 102 along an axis 126 that is substantially parallel to the longitudinal axis 124 of the barrel, though in some cases there may be a slight angle between these two axes 126 and 124.

The firearm grip 102 can include a backstrap element 118, often seen on 2011 style firearms (see, for example, FIGS. 2A and 2B), although this is not required. The backstrap element 118 may be a modular component, and many manufacturers offer interchangeable backstraps that enable shooters to adjust the grip size to match their hand dimensions, enhancing comfort and control. Where a modular backstrap element 118 is implemented, the firearm grip 102 and the backstrap element 118 may be affixed to each other via a pin 112 or other fastener that passes through apertures 114a, 114b, and 114c. Any elongated cylindrical member may be used in place of the pin 112. While the rail interface provides a certain level of fixation between the magazine well element 104 and the firearm grip 102, in some embodiments, hooked notches 116a, 116b, and 116c can be added to the magazine well element 104 allowing these notches 116a, 116b, and 116c to wrap around a portion of the pin 112, thereby more securely affixing the magazine well element 104 and the firearm grip 102.

The notches 116a, 116b, and 116c (also referred to herein as first notch 116a, second notch 116b, and third notch 116c, as well as outer notches 116a and 116c, and inner notch 116b) along with apertures 114a, 114b, and 114c (also referred to herein as first aperture 114a, second aperture 114b, and third aperture 114c, as well as outer apertures 114a and 114c, and inner aperture 114b) are configured to, when aligned, receive at least one fastener (such as pin 112) for enhancing engagement of the magazine well element 104 to the firearm grip 102. The fastener can be an elongated cylindrical member. The first and third notches or outer notches, 116a and 116c are oriented with an opening toward the rear of the magazine well element 104, while the second notch or inner/middle notch 116b has an opening oriented proximally. These orientations mean that the magazine well element 104 should be slid along the rail interface and coupled to the firearm grip 102 along with the backstrap element 118 before the pin 112 is inserted. If the pin 112 is in place before the magazine well element 104 is coupled to the firearm grip 102, then the pin 112 prevents the magazine well element 104 from fully traversing the rail interface. Similarly, once the pin 112 is fully engaged with the magazine well element 104, the firearm grip 102 and the backstrap element 118 (e.g., extending through notches 116a, 116b, and 116c, and apertures 114a, 114b, and 114c), the magazine well element 104, due to the orientation of the second or inner/middle notch 116b, cannot be removed thereby ensuring a firm engagement against vibrations and shocks.

While the firearm grip 102 has been shown and described as having a backstrap element 118, and while this element is common to 2011 style handguns, it is not required. In some embodiments, the pin 112 may merely pass through apertures in the distal end 103 of the firearm grip 102 without passing through an aperture in the backstrap element 118. In other embodiments, a pin may not be needed and the magazine well element 104 may merely slide rearward along the rail interface and another connection can ensure a secure attachment to the firearm grip 102. For instance, the notch 119 and detent 120 may provide sufficient attachment to prevent the magazine well element 104 from inadvertent loosening or removal. In the case of 1911 style hand guns the mainspring housing may include one or more apertures to help with receiving the pin 112 similar to how the backstrap element 118 includes aperture 114b.

Some figures in this disclosure may only show a lower portion of a firearm grip, but the features of the exemplary firearm grip shown in FIGS. 1A, 1B, 2A, and FIG. 2B can apply to any of these other embodiments. Further, while the firearm grips and magazine well elements are shown throughout this disclosure in the context of a hand gun grip assembly, the principle of the disclosed rail interface can be applied to other styles of firearm grip and magazine well, such as that of a long gun (e.g., rifle or carbine style firearm and shorter long guns such as submachine guns). Still further examples of firearms that may use the firearm grips and magazine well elements as disclosed herein include pistol-caliber carbines (PCCs), Personal Defense Weapons (PDWs), and any other firearms where the magazine is inserted into the grip.

Further, one of skill in the art will appreciate that advantages resulting from the features of various embodiments disclosed herein can apply to other embodiments. For example, magazine well element 104 provides improved ease of attachment and removal for the magazine well element 104 itself, and also enables faster and easier magazine insertion. In various aspects, the sliding axis 126 orientation enables improved ease of attachment and removal of the magazine well element 104 through a sliding motion. The attachment and removal of the magazine well element 104 may require a tool (e.g., a non-specialized tool or non-specialized piece of equipment) to insert and/or remove the pin.. The flared geometry of the magazine well element 104 may reduce the precision required during magazine insertion, potentially decreasing reload times. The modular nature of the assembly may allow users to interchange magazine well elements having different flare profiles to suit different applications or preferences. In addition, the notch 119 and detent 120 can improve security of the attachment of the magazine well element 104 to the firearm grip 102 in addition to that which is achieved by the primary rail interface. Further, the sliding axis 126 enables an assembly and disassembly motion may be performed in a direction that is convenient for users operating the firearm.

Referring to FIG. 2A, an illustrative exploded perspective view of the firearm grip assembly illustrates the relationship between multiple components. The assembly includes the firearm grip 102, the magazine well element 104, and a backstrap element 118. The firearm grip 102 includes the proximal rail portion 108 at its distal end. The proximal rail portion 108 may extend along one or more sides of the distal end of the firearm grip 102, providing a rail interface surface for engagement with the magazine well element 104. The magazine well element 104 includes the distal rail portion 110 at its proximal end. The distal rail portion 110 may be configured to receive and interface with the proximal rail portion 108 during sliding engagement along the sliding axis 126. In various embodiments, the distal rail portion 110 may include one or more channels or grooves that receive corresponding ridges or protrusions of the proximal rail portion 108. The sliding engagement between the proximal rail portion 108 and distal rail portion 110 may provide structural support and alignment between the firearm grip 102 and magazine well element 104.

In various embodiments, the magazine well element 104 features three notches at its rear portion: a first notch 116a, a second notch 116b, and a third notch 116c. These notches may be configured to interface with a fastening mechanism when the components are assembled. In some embodiments, the notches may be recesses or cutouts in the rear surface of the magazine well element 104. The firearm grip 102 includes corresponding apertures: a first aperture 114a, a second aperture 114b, and a third aperture 114c. These apertures may extend through the firearm grip 102, allowing a fastener to pass through the firearm grip 102 and engage with the notches in the magazine well element 104.

The backstrap element 118 may be positioned at the rear of the assembly. In various embodiments, the backstrap element 118 may include apertures that align with the first aperture 114a, second aperture 114b, and third aperture 114c in the firearm grip 102. Incorporation of the backstrap element 118 may provide additional advantageous aspects. For example, the backstrap element 118 may provide additional structural support and allow for customization of the grip profile to accommodate different hand sizes or user preferences.

In various aspects, the magazine well element 104 can include a detent 120 at its front portion. The detent 120 may provide a selective fixation mechanism when engaged with a corresponding feature on the firearm grip 102. In various embodiments, the detent 120 may be a protrusion that engages with a notch or recess in the firearm grip 102 or alternatively may contain a recess that receives a protrusion from the firearm grip 102.

In some aspects, FIG. 2A shows how the magazine well element 104 may slide onto the firearm grip 102 along the sliding axis 126, with the distal rail portion 110 engaging the proximal rail portion 108. The backstrap element 118 may be positioned to align an aperture 114b in the backstrap element 118 with the rear apertures 114a and 114c of the firearm grip 102, allowing a fastener (e.g., a pin 112, discussed further herein) to pass through the aligned apertures 114a, 114b, and 114c and notches 116a, 116b, and 116c to secure the assembly. This configuration provides several advantages. For example, the rail interface enables quick attachment and removal of the magazine well element 104. Use of multiple notches and apertures may provide secure fastening at multiple points, distributing loads and reducing stress concentrations. The inclusion of the backstrap element 118 may allow for further customization of the grip assembly. Aspects of the backstrap 118 may allow for improved material conditions for manufacturing (e.g., advantageous structural sizes). In addition, various embodiments of interchangeable backstraps may be used to accommodate different hand sizes and can also advantageously allow for improved personalized fitment for various conditions (e.g., gloved use).

Referring to FIG. 2B, a perspective view of a portion of the firearm grip assembly shows the illustrative engagement mechanism between components. The firearm grip 102 is shown with the backstrap element 118 positioned at the rear portion of the assembly. The magazine well element 104 is positioned at the lower portion of the firearm grip 102, forming part of the magazine receiving structure. A pin 112 extends through the assembly, passing through aligned apertures to secure the components together. The pin 112 may pass through apertures in the backstrap element 118, the firearm grip 102, and engage with notches in the magazine well element 104 (only aperture 114a is visible in FIG. 2B). In various embodiments, the pin 112 may be a cylindrical rod, a threaded fastener, or a quick-release pin. The aperture 114a is visible in the magazine well element 104, configured to receive the pin 112. In various embodiments, the aperture 114a may be a through-hole, a threaded hole, or a notch that receives a portion of the pin 112. The pin 112 may provide a fastening mechanism that enhances the engagement between multiple components, including at least some of the magazine well element 104, the firearm grip 102, and the backstrap element 118. In various embodiments, the pin 112 may prevent relative movement between components during firearm operation, reducing vibration and maintaining alignment. The pin 112 may be removable to allow disassembly of the components, enabling interchange of the magazine well element 104 or backstrap element 118.

Referring to FIGS. 3A and 3B, these figures show isometric views of the magazine well element 104. In various embodiments, the magazine well element 104 is a flared component that widens from a proximal end 105 toward the distal end 107. The distal end 107 includes the opening where a magazine first enters the magazine well element 104. In various embodiments, the distal end 107 may have a larger cross-sectional area than the proximal end 105, creating a funnel effect that guides magazine insertion.

In various embodiments, the configurations shown in FIG. 3A has a backstrap 118 and the magazine well element 104 includes the detent 120 positioned on a front portion of the component. The detent 120 may be configured to engage with a corresponding feature on the firearm grip 102 to enhance attachment between the components. In various embodiments, the detent 120 may be a protrusion that extends outward from the surface of the magazine well element 104. In the embodiments shown in FIG. 3A, at a rear portion of the magazine well element 104, the pin 112 is visible. The pin 112 may pass through apertures and notches to secure the magazine well element 104 to the firearm grip 102.

In various aspects, the magazine well element 104 exhibits a funnel-like geometry that expands outward from the proximal end 105 to the distal end 107. This geometry may provide an enlarged opening to facilitate magazine insertion during reloading operations. In various embodiments, the degree of flare may advantageously be selected based on various considerations; for example, providing a large insertion opening, or maintaining a desired size or profile.

Referring to FIG. 3C, an isometric view of the magazine well element 104 illustrates the component with additional detail. The magazine well element 104 is shown as a standalone component with a flared structure that expands from a proximal end toward the distal end 107. The distal end 107 represents the opening where a magazine first enters the magazine well element 104. The magazine well element 104 may include the distal rail portion 110 located at the proximal end of the magazine well element 104. The distal rail portion 110 may include elongated rail features that extend along an upper surface of the magazine well element 104, configured for sliding engagement with the corresponding proximal rail portion on the firearm grip, as discussed herein. For example, the rail features of the distal rail portion 110 may provide structural support and alignment during engagement, enabling the magazine well element 104 to slide onto the firearm grip in a controlled manner. The distal rail portion 110 may be configured to maintain secure mechanical connection with the proximal rail portion while allowing for attachment and removal of the magazine well element 104.

At the front portion of the magazine well element 104, the detent 120 is visible. The detent 120 may be configured to interface with a corresponding notch on the firearm grip 102 to enhance the secure attachment between the magazine well element 104 and the firearm grip 102. For example, the detent 120 may work in conjunction with the distal rail portion 110 to provide multiple points of connection between the magazine well element 104 and the firearm grip. The detent 120 may engage with the notch on the firearm grip after the magazine well element 104 has been slid into position through the rail interface, providing additional retention. In various embodiments, the detent 120 may provide a friction fit or snap fit engagement mechanism. In some respects, the detent 120 may be positioned to engage with the firearm grip 102 when the magazine well element 104 is fully seated on the rail interface, providing tactile and audible feedback to the user that the components are properly engaged.

The magazine well element 104 may further include the notch 116 located at a rear portion of the component. The notch 116 may be configured within a boss extending from the magazine well element 104, where the boss provides a reinforced structural foundation that enhances the load-bearing capacity of the notch 116. The notch 116 may be configured to receive a fastener, such as the pin, to enhance engagement of the magazine well element 104 to the firearm grip. The boss structure surrounding the notch 116 may distribute fastening loads across a broader area of the magazine well element 104, reducing stress concentrations and improving the durability of the connection. The notch 116 may be positioned to align with corresponding apertures in the firearm grip and the backstrap element when the magazine well element 104 is properly engaged through the distal rail portion 110.

The notch 116 may be shaped to accommodate a pin while providing secure retention of the pin within the magazine well element 104. The boss structure may provide enhanced structural stability by creating a thickened wall section around the notch 116, enabling the notch to withstand repeated insertion and removal of fasteners without deformation or wear. The notch 116 may work in combination with the distal rail portion 110 and the detent 120 to create a multi-point attachment system that provides robust connection between the magazine well element 104 and the firearm grip while enabling interchange of the magazine well element 104.

In various embodiments disclosed herein, the configurations may allow users to quickly interchange magazine well elements with different degrees of flare or size to accommodate different use applications. In various embodiments, as discussed herein, multiple magazine well elements with different flare profiles may be provided, allowing users to select the configuration that best suits their needs. For example, a user may install a large flare for competition and easily exchange it with a smaller flare for concealed carry. Illustrative embodiments of flare sizes can include, for example, carry (minimal flare), standard (standard flare), holster (additional flare), and combat/competition (maximum flare). For example, competition may use maximum flare because speed may have the greatest importance and weapon size concerns.may be minimal. In addition, concealed carry may desire to use minimum flare to optimize concealability, while external duty holster use (e.g., for military or law enforcement) may often use an unmodified grip (e.g., having a standard amount of flare) but some additional flare could be advantageous, since small increases in overall weapon size may be more tolerable in an external holster. However, in various embodiments, this may be balanced with a larger weapon size which can increase some disadvantages (e.g., snag hazards, environmental weapon damage, interference in confined spaces such as tunnels, aboard ships or in urban terrain, etc.).

Referring to FIG. 3D, this figure shows an illustrative isometric view of a magazine well element 104 in an exploded configuration with a backstrap 118. In FIG. 3D, a backstrap 118 is shown separated from magazine well element 104. In various aspects, the backstrap 118 may be sized to accommodate a boss with a singular aperture in the magazine wall element 104 (e.g., the boss encapsulates the lock pin hole to provide a more stable geometry). In some aspects, the backstrap 118 may jut at an angle from a flare portion, which may create an additional structural stop component for inserting the backstrap 118, and may complete an interior wall of a magazine chute.

Turning to FIG. 4A, this figure shows an illustrative isometric cross-sectional view of a firearm grip assembly showing an engagement between a firearm grip and magazine well element. The cross-section cuts through the middle of the backstrap 118 and detent 120. In various aspects, the notch 119 may be configured to engage with a corresponding detent 120, which may provide alignment and mechanical engagement between the components. At least one notch 116 may be positioned to receive a fastening pin when the magazine well element 104 is assembled with the firearm grip 102 and the backstrap element 118. In various aspects, the notch 116 may be located in alignment with corresponding apertures in both the firearm grip 102 and the backstrap element 118, enabling a pin to pass through and secure the components together.

In various embodiments, the detent 120 may be integrated within the magazine well element 104 to interface with the notch 119 and provide additional retention between the magazine well element 104 and the firearm grip 102. For example, the detent 120 extending from an internal surface of the magazine well element 104 may create a mechanical engagement point that works in conjunction with the rail interface and the pin fastening system. The detent 120 may provide engagement feedback (e.g., by engaging with the notch 119) when the magazine well element 104 is properly positioned relative to the firearm grip 102.

The cross-sectional view of FIG. 4A may show the magazine well element 104 featuring a flared opening that widens from the proximal end toward the distal end, creating a funnel effect to facilitate magazine insertion during reloading operations. For example, the flared geometry may advantageously be maintained while incorporating various attachment features as described herein (e.g., the notch 119, the notches 116, and the detent 120), ensuring that the magazine well element 104 provides both functional magazine guidance and secure mechanical connection to the firearm grip assembly.

Turning to FIG. 4B, this figure shows an illustrative isometric cross-sectional view of a firearm grip assembly showing an engagement between a firearm grip and magazine well element. For example, in various embodiments, the firearm grip 102 may include a proximal rail portion 108a that includes a protruding rail element that extends from the body of the firearm grip 102 and may be configured to interface with a corresponding distal rail portion 110a on the magazine well element 104. The proximal rail portion 108a may feature a geometric profile designed to provide structural support and alignment during engagement operations. The distal rail portion 110a may be shaped to receive and engage with the proximal rail portion 108a through a sliding motion along the sliding axis 126. The distal rail portion 110a may form a channel or slot configuration that accommodates the proximal rail portion 108a, enabling controlled sliding engagement between the two components for interlocking the two components.

The section view may illustrate how the rail interface provides a guided pathway for engagement between the magazine well element 104 and the firearm grip 102. The proximal rail portion 108a may serve as a guide rail that directs the movement of the magazine well element 104 during attachment, while the distal rail portion 110a may provide the corresponding guide channel that follows the path defined by the proximal rail portion 108a. This guided engagement may ensure consistent and repeatable attachment of the magazine well element 104 to the firearm grip 102.

Referring to FIG. 5A-5B, the magazine well element 104 may exhibit a flared structure that expands from a proximal end toward a distal end, creating a funnel-like configuration designed to facilitate magazine insertion during reloading operations. The flared geometry may provide an enlarged opening at the distal end that serves as a target area for magazine insertion, while the narrower opening at the proximal end may direct the magazine into the firearm grip 102 when the components are assembled together. In various aspects, the magazine well element may include a detent 120 positioned on a front surface. The detent 120 may protrude from the front surface and may be configured to provide a mechanism for selective engagement with a corresponding feature on the firearm grip when the magazine well element 104 is attached to the firearm grip 102. The detent 120 may be shaped to create a mechanical connection point that enhances secure attachment between the magazine well element 104 and the firearm grip 102.

The detent 120 may be positioned to interface with a notch 119 or corresponding feature on the firearm grip, creating a selective fixation mechanism that works in conjunction with the rail interface system. The detent 120 may provide immediate engagement feedback when the magazine well element is properly positioned relative to the firearm grip, and may help prevent inadvertent separation of the components during firearm operation.

The magazine well element may include an aperture located at a rear portion of the component. The aperture may be configured to receive a pin 112 for securing the magazine well element 104 to the firearm grip 102 when the components are assembled together. The aperture may be positioned to align with corresponding apertures in the firearm grip 102 and backstrap element 118 when the magazine well element is engaged through the rail interface system.

Referring to FIG. 5C, the magazine well element 104 may have various structural features that enable both sliding engagement with a firearm grip 102 and secure attachment through multiple connection points. The magazine well element 104 may extend from the proximal end 105 to the distal end 107 and be configured to provide an enlarged opening for magazine insertion while maintaining secure mechanical connection to the firearm grip 102.

The magazine well element 104 may include the distal rail portion 110 positioned at the proximal end 105 of the component. The distal rail portion 110 may include rail features that extend along surfaces of the magazine well element 104 and may be configured for sliding engagement with a corresponding proximal rail portion on the firearm grip. In some aspects, the distal rail portion 110 shown in FIG. 5C may have a modified profile that provides enhanced engagement characteristics. For example, the distal rail portion 110 in FIG. 5C may incorporate a broader engagement surface and the increased surface area may advantageously provide enhanced load distribution across the rail interface (e.g., improving the durability and reliability of the connection between the magazine well element 104 and the firearm grip 102 during repeated assembly and disassembly operations). In some embodiments, the broader engagement surface may also enhance the guidance characteristics of the rail interface, ensuring more precise alignment during sliding engagement operations. In various aspects, the rail features of the distal rail portion 110 may extend along a greater length of the magazine well element 104 and this may provide increased contact area with the corresponding proximal rail portion on the firearm grip, enhancing the structural stability of the connection during firearm operation.

The distal rail portion 110 may provide the primary mechanical interface that enables the magazine well element 104 to slide onto the firearm grip in a controlled manner along a predetermined axis.

The notch 116 may be positioned to align with corresponding apertures in the firearm grip 102 and the backstrap element 118 when the magazine well element 104 is properly engaged through the distal rail portion 110.

The notch 116 may be shaped to accommodate a pin while providing secure retention of the pin within the magazine well element 104. As shown in various embodiments described herein, the boss structure may provide enhanced structural stability by creating a thickened wall section around the notch 116, enabling the notch to withstand repeated insertion and removal of fasteners without deformation or wear. The notch 116 may work in combination with the distal rail portion 110 and the detent 120 to create a multi-point attachment system that provides robust connection between the magazine well element 104 and the firearm grip while enabling improved ease of interchange of the magazine well element 104.

Turning to FIG. 6A, this figure shows an illustrative isometric cross-sectional view of a firearm grip assembly showing an engagement between a firearm grip and magazine well element.

In various aspects, the notch 116 may be located in alignment with corresponding apertures in both the firearm grip 102 and the backstrap element 118, enabling a pin to pass through and secure the components together.

In various embodiments, the detent 120 may be integrated within the magazine well element 104 to interface with the notch 119 and provide additional retention between the magazine well element 104 and the firearm grip 102. For example, the detent 120 extending from an internal surface of the magazine well element 104 may create a mechanical engagement point that works in conjunction with the rail interface and the pin fastening system. The detent 120 may provide engagement feedback (e.g., by engaging with the notch 119) when the magazine well element 104 is properly positioned relative to the firearm grip 102.

In some aspects, the cross-sectional view of FIG. 12A may show the magazine well element 104 featuring a flared opening that widens from the proximal end toward the distal end, creating a funnel effect to facilitate magazine insertion during reloading operations. For example, the flared geometry may advantageously be maintained while incorporating various attachment features as described herein (e.g., the notch 119, the notches 116, and the detent 120), ensuring that the magazine well element 104 provides both functional magazine guidance and secure mechanical connection to the firearm grip assembly.

Referring to FIG. 12B, the proximal rail portion 108d may have geometric characteristics that differ from other proximal rail portions described herein. For example, the proximal rail portion 108e may feature a modified cross-sectional profile with enhanced structural dimensions, providing improved load distribution and engagement characteristics. In various aspects, the proximal rail portion 108e may extend from the distal end of the firearm grip 102 with a broader engagement surface designed to provide superior structural support. In some aspects, the proximal rail portion 108e may have a cross-sectional profile with increased length extending towards the distal end 107 of the magazine well element. In various aspects, the geometry of the proximal rail portion 108e may extend from the body of the firearm grip 102 with a longer engagement surface designed to provide improved structural support and load distribution characteristics. The magazine well element may include a corresponding distal rail portion 110e at the proximal end 105 of the magazine well element.

The proximal rail portion 108e may be designed to interface with a distal rail portion 110e of the magazine well element and the geometric modifications of the proximal rail portion 108e and distal rail portion 110e may provide enhanced functionality through increased contact area and improved load distribution. The broader engagement surfaces may distribute mechanical loads more effectively across the rail interface, reducing stress concentrations and improving the durability of the connection. The modified geometry may also provide enhanced guidance characteristics during assembly operations, ensuring more precise alignment and smoother sliding engagement. In various aspects, the advantages of the 108e and 110e rail geometry may include improved structural integrity through the enlarged contact surfaces, enhanced manufacturing tolerances through the modified profile dimensions, and superior operational reliability through the optimized engagement characteristics.

The embodiments shown in FIGS. 11-12 may have adjusted rail geometry that improves the load distribution characteristics of the proximal rail portion 108e and the distal rail portion 110e by increasing the contact area between the rail portions, providing additional structural support that improves the durability and reliability of the connection during repeated assembly and disassembly operations. The increased contact area may also improve the guidance characteristics of the rail interface, ensuring more precise alignment during sliding engagement operations.

Referring to FIG. 13A, a rear perspective view of the firearm grip assembly may demonstrate an integrated design configuration where the firearm grip 102 and the magazine well element 104 function as a unified structural unit. For example, the magazine well element 104 may be positioned at a lower portion of the assembly and may interface with the firearm grip 102 to create the combined grip and magazine receiving structure. The magazine well element 104 may include a curved, funnel-like structure that extends downward from the firearm grip 102, providing an enlarged opening for magazine insertion operations. The downward extension of the magazine well element 104 may create additional clearance and guidance area that facilitates magazine insertion while maintaining the overall compactness of the integrated assembly. The flared opening of the magazine well element 104 may expand progressively from the interface area with the firearm grip 102 toward the distal end of the magazine well element 104. For example, the magazine well element 104 may feature a wider opening at the distal end compared to standard magazine well configurations, enabling faster and more reliable magazine insertion during reloading operations. The enlarged opening may reduce the likelihood of insertion errors by providing a larger target area for magazine positioning, particularly in high-stress situations where precise magazine alignment may be challenging. In various aspects, the combined grip and magazine receiving structure may provide enhanced functionality compared to separate grip and magazine well components by eliminating potential interface issues and providing optimized geometry that serves both gripping and magazine insertion functions.

Referring to FIG. 13B, the magazine well element 104 may be shown as a separate component positioned adjacent to the firearm grip 102. The separate positioning may illustrate how the magazine well element 104 functions as a modular unit that can be removed from and attached to the firearm grip 102 to enable users to select from multiple magazine well element configurations while maintaining the same basic firearm grip 102 structure.

Referring to FIG. 13C, the firearm grip assembly may be shown with the magazine well element 104 in a disengaged position with the firearm grip 102, where the magazine well element 104 is positioned below the firearm grip 102 with a vertical separation that indicates the direction of sliding engagement between the components. The vertical separation may demonstrate the path of movement that the magazine well element 104 follows as the magazine well element 104 slides vertically relative to the firearm grip 102 to achieve a connection of the components. The vertical sliding motion may occur along an axis that enables controlled engagement by inserting the backstrap 118 into the firearm grip 102 while maintaining proper orientation between the magazine well element 104 and the firearm grip 102 throughout the attachment process.

The magazine well element 104 may include a notch 1319 located at a front upper portion of the component. The notch 1319 may be configured to interface with a corresponding detent 1320 on the firearm grip 102 during the engagement process, providing alignment and mechanical connection between the components when the magazine well element 104 reaches the fully engaged position. The detent 1320 may extend from a front surface of the magazine well element 104 and may be shaped to create a mechanical engagement point that enhances the secure attachment between the magazine well element 104 and the firearm grip 102.

The detent 1320 may serve as an alignment feature that guides the magazine well element 104 into proper positioning relative to the firearm grip 102 during the vertical sliding engagement process. The detent 1320 may be positioned to engage with a corresponding receiving notch 1319 on the firearm grip 102, e.g., creating a selective fixation mechanism that provides alignment confirmation and prevents inadvertent movement once the components achieve full engagement. The engagement between the detent 1320 and the corresponding receiving notch 1319 may provide immediate feedback to indicate successful positioning of the magazine well element 104.

Referring to FIG. 13D, the magazine well element 104 may be shown in embodiments where the magazine well element 104 and the backstrap element function as a single integrated component. For example, the magazine well element 104 may include three apertures positioned along a rear portion of the component that enable fastener engagement for securing the integrated component to the firearm grip 102. The first aperture 114a, the second aperture 114b, and the third aperture 114c may be arranged in a linear configuration that aligns with corresponding features on the firearm grip 102 when the magazine well element 104 is properly positioned for attachment.

The first aperture 114a may be positioned at a first location along the rear portion of the magazine well element 104 and may be configured to receive a fastener for securing the integrated component to the firearm grip 102. The second aperture 114b may be positioned at a second location along the rear portion and may be aligned with the first aperture 114a to provide multiple fastening points for enhanced connection security. The third aperture 114c may be positioned at a third location along the rear portion, completing the linear arrangement of apertures that enables comprehensive fastening of the magazine well element 104 to the firearm grip 102. The aperture configuration may enable a single pin (not shown in FIG. 13D) to pass through multiple apertures simultaneously, or may accommodate multiple pins or other fasteners that provide distributed connection points across the rear portion of the magazine well element 104.

As further shown in FIG. 13D, the magazine well element 104 may include the detent 1320 extending from a front portion of the component. The detent 1320 may be configured to engage with a corresponding feature on the firearm grip 102 to enhance alignment and reduce movement during use.

The magazine well element 104 may incorporate a rail interface system that enables sliding engagement with the firearm grip 102 along an axis substantially parallel to the direction of magazine insertion. The rail interface system may include a first rail portion 122a and a second rail portion 122b (e.g., a set of rails) positioned on opposite sides of an interior surface of the magazine well element 104. The first rail portion 122a may extend along a first side of the interior surface and may be configured to interface with a corresponding rail feature on the firearm grip 102. The second rail portion 122b may extend along a second side of the interior surface and may be positioned opposite to the first rail portion 122a, e.g., to provide balanced engagement characteristics.

Corresponding to the first rail portion 122a and the second rail portion 122b, the magazine well element 104 may include a first rail slot 124a and a second rail slot 124b (e.g., a set of rail slots). The first rail slot 124a may be positioned to receive a corresponding rail feature from the firearm grip 102 that interfaces with the first rail portion 122a. The second rail slot 124b may be positioned to receive another corresponding rail feature from the firearm grip 102 that interfaces with the second rail portion 122b. The first rail slot 124a and the second rail slot 124b may be configured as recessed channels designed to accommodate complementary rail portions from the firearm grip 102. The first rail slot 124a and the second rail slot 124b may be oriented to enable sliding engagement along an axis substantially parallel to the direction of magazine insertion. This orientation may facilitate smooth sliding motion during attachment and removal operations while maintaining proper alignment between the magazine well element 104 and the firearm grip 102.

The rail interface system formed by the first rail portion 122a, the second rail portion 122b, the first rail slot 124a, and the second rail slot 124b may provide a secure mechanical connection between the magazine well element 104 and the firearm grip 102. The rail portions and rail slots may create interlocking geometry that distributes loads across the interface surfaces while maintaining secure attachment during firearm operation.

The rail interface configuration may be particularly suited for 2011 style handguns where the backstrap element common to such firearms may include protruding portions and recessed portions that are oriented substantially in line with the direction of cartridge feeding. The first rail portion 122a and the second rail portion 122b may interface with these protruding portions, while the first rail slot 124a and the second rail slot 124b may accommodate the recessed portions, creating a comprehensive rail interface system that utilizes the existing structural features of 2011 style handgun designs.

Referring to FIG. 14A, the firearm grip assembly may demonstrate a comprehensive modular configuration that integrates the firearm grip 102, the magazine well element 104, and the backstrap element 118 into a unified system that enables secure attachment while maintaining improved interchangeability capabilities. The modular configuration may provide a complete grip solution that combines multiple functional components into a single assembly that can be customized for different applications, user preferences, and operational requirements without requiring modification of the primary firearm structure. The modular configuration may include the notch 1319 positioned on the firearm grip 102 at a front portion of the component, configured to provide alignment and mechanical engagement with the detent 1320 on magazine well element 104. Aperture 114 may be present in the backstrap element 118 and may be configured to receive a pin for securing the modular assembly components together. The aperture 114 may be positioned to align with corresponding features in both the magazine well element 104 and the firearm grip 102 when the components are properly engaged through the rail interface system.

The modular design may be achieved through the rail interface system that enables the magazine well element 104 to be attached to and removed from the firearm grip 102 with the use of non- specialized tools or equipment. The rail interface system may provide guided engagement that directs the magazine well element 104 into proper alignment with the firearm grip 102 along a predetermined sliding axis. The guided engagement may ensure that the notch 1319, the detent 1320, and the aperture 114 align correctly for proper mechanical connection and fastener insertion.

The rail interface system may enable interchangeability by providing standardized connection characteristics that remain consistent regardless of which magazine well element configuration is installed. The standardized interface may ensure that different magazine well elements provide the same level of secure attachment and reliable operation while offering varying functional characteristics such as different degrees of flare, alternative surface configurations, or specialized features for specific applications. The consistent interface characteristics may enable users to build a collection of magazine well elements for different purposes while using the same firearm grip 102.

The interchangeability enabled by the rail interface system may allow users to quickly adapt the magazine well configuration for different shooting applications without requiring multiple complete grip assemblies. A magazine well element with a larger flare may be installed for competition shooting applications where maximum reloading speed and enlarged target area for magazine insertion are desired. A magazine well element with minimal flare may be installed for concealed carry applications where compactness and reduced profile are prioritized. The rail interface system may enable this interchange to be accomplished quickly, e.g., using non-specialized tools (or non-specialized equipment) that do not require technical expertise. Further, the modular configuration demonstrated in FIG. 14A may illustrate how the rail interface system enables improved interchange while maintaining the secure attachment needed for reliable firearm operation.

Turning to FIG. 14B, this figure shows that the firearm grip 102 may include a proximal portion 108f located at the distal end of the firearm grip 102. The proximal portion 108f may be a flat or angled surface that extends along a lower portion of the firearm grip 102 and may be integrated into the body structure of the firearm grip 102. The protruding rail element may interface with a corresponding flat or angled distal portion 110f on a magazine well element during assembly operations.

The embodiments shown in FIGS. 13-14 may show an interchangeable component that assembles using the backstrap element 118 and uses a pin to lock the assembly together. This alternative approach may provide enhanced structural characteristics by integrating the backstrap functionality with the magazine well element, creating a single component that provides improved structural strength and ease of assembly. The pin locking system may enable the integrated component to be quickly installed or removed requiring only non-specialized tool without extensive disassembly operations. The various geometries shown for the magazine well element and/or backstrap in FIGS. 1-14 are not limiting. For example, other engagement geometries could include a pin to lock two components together, tongue-and-groove configuration that could be glued together, snap fingers, and slots to create a snap fit. Further, any of these geometries may be located at any position(s) on the elements disclosed herein. As one example, a pin (or more than one pin) could be incorporated on a side of the magazine well flare opposite the backstrap.

Turning to FIG. 15, this figure shows an illustrative flow chart for methods 1500 of assembling a firearm grip assembly. The methods 1500 may include a series of steps for engaging a magazine well element with a firearm grip. The methods 1500 may be applicable to multiple embodiments, for example methods including embodiments utilizing a horizontal sliding rail interface and embodiments utilizing a vertical sliding engagement with an integrated backstrap and magazine well element.

The flowchart starts at step 1501. At step 1503, the methods may include aligning the magazine well element with the firearm grip. In embodiments utilizing a horizontal sliding rail interface, aligning may include positioning the distal rail portion of the magazine well element adjacent to the proximal rail portion of the firearm grip, with the sliding axis oriented substantially parallel to the longitudinal axis of a firearm barrel. In embodiments utilizing a vertical sliding engagement with an integrated backstrap and magazine well element, aligning may include positioning the combined backstrap and magazine well component below the firearm grip.

At step 1505, the methods may include sliding engagement. In various embodiments using a horizontal sliding rail interface, sliding engagement may include sliding the magazine well element onto the firearm grip (e.g., along the sliding axis 126, with the distal rail portion 110 engaging the proximal rail portion 108 through sliding motion substantially parallel to the longitudinal axis 124 of a firearm barrel and substantially oblique to the cartridge traversal axis 122). In embodiments utilizing a vertical sliding engagement, sliding engagement may include sliding the combined backstrap and magazine well element onto the firearm grip along an axis substantially parallel to the cartridge traversal axis, with the rail slots (e.g., first rail slot 124a and second rail slot 124b) interfacing with corresponding recessed portions on the firearm grip to secure the backstrap and magazine well element and preclude lateral movement.

At step 1507, the method 1500 proceeds to step 1509 if there is a detent present, and to step 1511 if there is no detent present. Step 1509 may include detent engagement. For example, in embodiments utilizing a horizontal sliding rail interface, detent engagement may include continuing the sliding motion until the detent engages, providing tactile and audible feedback that the magazine well element is fully seated on the firearm grip. The detent 120 may provide a snap fit engagement (e.g., with a corresponding notch 119 on the firearm grip 102). In embodiments utilizing a vertical sliding engagement, protrusion engagement may include the protrusion 1320 engaging with a corresponding receiving notch on the firearm grip, which may provide alignment. If there is no detent, the method may proceed to step 1511.

At step 1511, the method proceeds to step 1515 if there is no backstrap, and to step 1513 if there is a backstrap. Step 1513 may include sliding the backstrap element onto the assembly. For example, after the magazine well element is fully seated on the firearm grip, the backstrap element may be slid onto the firearm grip until it is fully seated.

At step 1515, The notches and/or protrusions may be aligned. For example, notches and/or protrusions on the magazine well, the backstrap, and the firearm grip may be aligned when the magazine well element and backstrap element are fully seated onto the firearm grip. In some respects, the notch (e.g., notch 116) may be positioned to align with corresponding apertures in the firearm grip and the backstrap element when the magazine well element is properly engaged through the distal rail portion. In various aspects, the aperture (e.g., aperture 114) may be positioned to align with corresponding features in both the magazine well element and the firearm grip. Once the notches and/or apertures are aligned, a pin may be inserted through the apertures and/or notches in step 1517. The pin, once inserted, may securely attach the magazine well element to the firearm grip.

Step 1519 may include a disassembly determination. If disassembly is not desired, then the method may proceed to the end at step 1525. However, disassembly may be desired and the method may proceed to step 1521. Disassembly may be desired for various reasons, e.g., it may be desired in order to swap magazine well elements when a different flare configuration is desired.

At step 1521, the method 1500 may include removing the pin (e.g., pin 112) from the assembly. At step 1523, after the pin is removed, the magazine well element and/or backstrap may be removed. For example, In various embodiments using a horizontal sliding rail interface, sliding engagement may include sliding the magazine well element off of the firearm grip (e.g., along the sliding axis 126, with the distal rail portion 110 disengaging from the proximal rail portion 108 through sliding motion substantially parallel to the longitudinal axis 124 of a firearm barrel and substantially oblique to the cartridge traversal axis 122), and if a backstrap element is used, the backstrap element may be slidingly removed prior to removal of the magazine well element. In embodiments utilizing a vertical sliding engagement, sliding disengagement may include sliding the combined backstrap and magazine well element off of the firearm grip along an axis substantially parallel to the cartridge traversal axis, with the rail slots (e.g., first rail slot 124a and second rail slot 124b) interfacing with corresponding recessed portions on the firearm grip to remove the backstrap and magazine well element. In various aspects, removal may further include disengaging a detent by applying force to overcome a snap fit or friction fit engagement. To slidingly remove elements, movement in a direction opposite to the assembly direction may be used. After the magazine well element and/or backstrap element are removed, then the method ends at step 1525. One of skill in the art will appreciate that advantages resulting from the features of various embodiments disclosed herein can apply to other embodiments. For example, in various embodiments disclosed herein, the interlocking configuration of the magazine well element 104 and the firearm grip 102 may create a mechanical interface that advantageously distributes loads between the components while maintaining secure attachment during firearm operation. For example, in various embodiments, the rail interface (e.g., the proximal rail portion 108 and the distal rail portion 110) may enable the magazine well element 104 to slide onto the firearm grip 102 along an axis substantially parallel to the longitudinal axis 124 of a firearm barrel. The rail interface formed by the proximal rail portion 108 and the distal rail portion 110 may provide structural support that withstands the forces encountered during magazine insertion and removal operations. The rail interface may maintain secure engagement while allowing for controlled movement during attachment and removal of the magazine well element 104. In additional embodiments, the rail interface may allow for controlled movement during attachment and removal of the magazine well element 104 that enables improved ease of attachment or removal.

In various embodiments, the magazine well element 104 may include a singular boss structure that may advantageously provide structural reinforcement around the rail interface area while accommodating the pin engagement mechanism. For example, the magazine well element (or the integrated component) can allow for a smoother transition between the grip and the magazine well flare, to provide a more comfortable user interface, if desired. The boss may have one or more apertures or notches that create the opening for the pin 112, enabling the pin 112 to pass through aligned notches and/or apertures in the magazine well element 104, the firearm grip 102, and the backstrap element 118. In various aspects, rail configurations may guide the magazine well element 104 into proper alignment with the firearm grip 102, ensuring that the apertures and notches align correctly for pin insertion. The rail interface and/or detent may advantageously provide immediate feedback to the user regarding proper engagement, with the interlocking geometry preventing improper assembly configurations.

The magazine well element 104 may advantageously function as a modular component that can be manufactured in various sizes and styles, and using various materials, to provide different degrees of flare for different applications. The rail interface and/or detent may enable the magazine well element to be securely attached to the firearm grip while allowing for improved ease of interchange with other magazine well elements having different characteristics. For example, the modularity can allow a user to more easily, and with less tools (or a non-specialized tool), adjust the grip to suit the user’s requirements at any given time.

The various embodiments disclosed herein may incorporate features from multiple figures. In various aspects, the rail interface mechanism illustrated in FIG. 1B and FIG. 4B may be combined with the detent engagement shown in FIG. 3C and FIG. 5C. In various aspects, the pin fastening mechanism illustrated in FIG. 2B and FIG. 7A may be combined with the backstrap integration shown in FIG. 2A and FIG. 13A. In various aspects, the vertical sliding engagement mechanism illustrated in FIG. 13C and FIG. 13D may be combined with the flared geometries shown in other figures. In various aspects, the faceted design illustrated in FIG. 9A may be combined with the leg-like extensions shown in FIG. 12B. These combinations demonstrate the modular and adaptable nature of the disclosed magazine well attachment system, allowing for customization to suit different user preferences and operational requirements.
