Description
TECHNICAL FIELD

This document relates to the technical field of (and is not limited to) a firearm magazine having an internal spring and a spring-adjustment assembly for the internal spring, and/or method therefor, and/or a firearm magazine including an attachable telescopic spring-decompression mechanism, or a firearm magazine including a spring-adjustment assembly (spring-decompression mechanism) configured to remain (stay) mounted to (affixed to) the firearm magazine, and interacting with a magazine spring contained in the firearm magazine.

BACKGROUND

A firearm is a portable gun or a barreled weapon that launches one or more projectiles (bullets) often driven by an explosive force. Modern firearms are usually described by caliber (bore diameter or, in the case of shotguns, gauge), type of action employed (muzzle, breech, lever, bolt, pump, revolver, semi-automatic, automatic, etc.), and/or the means of deportment (hand-held or mechanical mounting).

SUMMARY

It will be appreciated that there exists a need to mitigate (at least in part) at least one problem associated with the existing firearm magazines (also called the existing technology). After much study of the known systems and methods with experimentation, an understanding of the problem and its solution has been identified and is articulated as follows:

Firearms magazines that require loading firearm cartridges generally have a strong spring within the magazine allowing each successive cartridge to be positioned at the mouth of the magazine, ready for firing. In order to charge a magazine by hand, cartridges already in the magazine may be pushed downward to make a space for the next cartridge to be inserted. Speed of loading is often necessary, particularly in combat situations, target practice, etc. In other situations also, such as hunting, time is valuable and a device for rapid magazine charging is useful. With small cartridges, it may be very difficult to charge a magazine quickly using human hands only. Therefore, numerous different devices, such as speed loaders, are used in order to load ammunition into the firearm magazine. Moreover, these devices (speed loaders) are frequently misplaced and/or lost altogether, and result in inconvenience and/or additional expense for users of firearm magazines, or unwanted injury when manually loading ammunition into the magazine without the device (the known speed loader or known ammunition loader).

To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a first major aspect) an apparatus. The apparatus includes (and is not limited to) a firearm magazine having an ammunition spring. A spring-adjustment assembly is configured to selectively reduce the spring tension in the ammunition spring in such a way that the spring-adjustment assembly permits relatively easier loading of ammunition into the firearm magazine. The spring-adjustment assembly is mounted to the firearm magazine in such a way that the spring-adjustment assembly is not removable from the firearm magazine once the firearm magazine is securely coupled to the firearm.

To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a second major aspect) an apparatus. The apparatus includes a firearm magazine configured to be selectively received by, and coupled to, a firearm. An ammunition spring (also called an internal spring) is received, at least in part, in the firearm magazine. A spring-adjustment assembly is mounted to the firearm magazine, and is also cooperative (interactable) with the ammunition spring once (A) the firearm magazine is received by, and coupled to, the firearm, and (B) the firearm magazine is removed from the firearm. The spring-adjustment assembly remains with the firearm magazine so that the spring-adjustment assembly is not inadvertently lost or misplaced once the firearm magazine is removed from the firearm.

To mitigate, at least in part, at least one problem associated with the existing technology, there is provided (in accordance with a third major aspect) a method. The method is for using a firearm magazine configured to be selectively received by, and coupled to, a firearm, and in which an ammunition spring is received, at least in part, in the firearm magazine. The method includes mounting a spring-adjustment assembly to the firearm magazine so that the spring-adjustment assembly is interactable with the ammunition spring once the firearm magazine is received by, and coupled to, the firearm, and once the firearm magazine is removed from the firearm. The spring-adjustment assembly remains with the firearm magazine so that the spring-adjustment assembly is not inadvertently lost or misplaced once the firearm magazine is removed from the firearm.

Other aspects are identified in the claims.

For the description, the terms “upper,” “lower,” “left,” “rear,” “right,” “front,” “vertical,” “horizontal,” and derivatives thereof shall relate to the examples as oriented in the drawings. There is no intention to be bound by any expressed or implied theory in the preceding Technical Field, Background, Summary or the following detailed description. It is also to be understood that the devices and processes illustrated in the attached drawings, and described in the following specification, are exemplary embodiments (examples), aspects and/or concepts defined in the appended claims. Hence, dimensions and other physical characteristics relating to the embodiments disclosed are not to be considered as limiting, unless the claims expressly state otherwise. It is understood that the phrase “at least one” is equivalent to “a”. The aspects (examples, alterations, modifications, options, variations, embodiments and any equivalent thereof) are described regarding the drawings. It should be understood that the invention is limited to the subject matter provided by the claims, and that the invention is not limited to the particular aspects depicted and described.

FIGS. 1, 2A and 2B depict views of a prior art embodiment of a known firearm magazine 901 for usage with a firearm 900. FIG. 1 depicts a perspective rear view of an embodiment of the firearm 900 (which is depicted as a pistol). FIG. 2A depicts a side view of an embodiment of a known firearm magazine 901 of FIG. 1. FIG. 2B depicts a cross-sectional view through a cross-sectional line A-A of the known firearm magazine 901 of FIG. 2A.

Referring to the embodiments as depicted in FIGS. 1, 2A and 2B, the firearm 900 (such as, a pistol 905, etc.) is configured to securely receive (at least in part) a known firearm magazine 901, and entirely release the known firearm magazine 901 (also called a prior art magazine). The known firearm magazine 901 is configured to receive a plurality of bullets 902 (preferably, in a single file manner, one after the other) within or into a known internal well 904 (also called a prior art internal well) that is defined by the known firearm magazine 901. The firearm 900 includes a downwardly-extending handle 903 configured to operatively receive (securely receive) the known firearm magazine 901. This is done in such a way that the known firearm magazine 901 may dispense the bullets 902 into a firing chamber (known and not depicted) of the firearm 900 (one at a time).

A known magazine spring 906 (also called a prior art magazine spring or internal spring) is positioned in the known firearm magazine 901. Once positioned, the known magazine spring 906 is configured to urge the bullets 902 contained in the known firearm magazine 901 toward an exit portal of the known firearm magazine 901 (and then into the firearm 900). When the firearm magazine 901 is not received in the firearm 900, a detent mechanism (known and not depicted, which is a catch that prevents motion until released) prevents the bullets 902 from exiting the firearm magazine 901. The known magazine spring 906 is configured to make contact with a known magazine floor 908 (also called a prior art magazine floor, or the floor 908). The floor 908 is positioned at the bottom section of the firearm magazine 901. The known magazine spring 906 pushes against the known magazine floor 908 in such a way that the known magazine spring 906 urges the bullets 902 contained in the known firearm magazine 901 toward the exit portal of the known firearm magazine 901.

FIGS. 3 to 15 depict views in accordance with a first embodiment of an apparatus including a synergistic combination of a firearm magazine 102, an ammunition spring 106 and a spring-adjustment assembly 108. FIGS. 3 to 8 depict side views of the first embodiment of the apparatus. FIGS. 9 to 11 and 13 depict perspective views of embodiments of the apparatus of FIG. 6. FIGS. 12, 14 and 15 depict cross-sectional schematic views of embodiments of the apparatus of FIG. 6.

The firearm magazine 102 is combined with the spring-adjustment assembly 108. The spring-adjustment assembly 108 may be called an attachable telescopic spring decompression mechanism, or a built-in ammunition loader. More specifically, the firearm magazine 102 includes a built-in ammunition loader configured to facilitate loading of ammunition into the firearm magazine 102, and to increase capacity of the ammunition carried by the firearm magazine 102 (where applicable and permitted by law and/or gun regulations). The apparatus includes an ammunition loader configured to load ammunition into the firearm magazine 102, in which the ammunition loader is built (integrated) into, or configured to be built into (as a retrofit kit), the firearm magazine 102.

In general terms, the apparatus includes (and is not limited to) a firearm magazine 102, and a spring-adjustment assembly 108 (also called an ammunition loader) that is mounted to the firearm magazine 102. The spring-adjustment assembly 108 is not removable from the firearm magazine 102 once the firearm magazine 102 is securely coupled to (received by) the firearm 900.

Preferably, the firearm magazine 102 has an ammunition spring 106. The spring-adjustment assembly 108 is configured to selectively reduce the spring tension in the ammunition spring 106 in such a way that the spring-adjustment assembly 108 permits relatively easier loading of ammunition into the firearm magazine 102. The spring-adjustment assembly 108 is mounted to the firearm magazine 102 in such a way that the spring-adjustment assembly 108 is not removable from the firearm magazine 102 once the firearm magazine 102 is securely coupled to the firearm 900.

Preferably, the apparatus provides a telescopic construction. Once the user presses a button, the spring-adjustment assembly 108, in use, extends (extends downwardly) from the firearm magazine 902 and away from the firearm 900. In this manner, the spring tension of the ammunition spring 106 is relaxed (released or decompressed, at least in part) in order to allow relatively easier loading of ammunition (bullets) into the firearm magazine 102 (because there is relatively less spring tension in the ammunition spring 106). The spring-adjustment assembly 108 is configured to selectively release, at least in part, spring tension in the ammunition spring 106 in order to allow relatively easier loading of ammunition into the firearm magazine 102.

Once the firearm magazine 102 has been loaded with fresh ammunition, the spring tension of the ammunition spring 106 is increased as a result. That is, the spring tension is increased by pressing upwardly on a lower part of the spring-adjustment assembly 108. The spring-adjustment assembly 108 remains secured to the firearm magazine 102 with a pair of oppositely-positioned catch-release buttons 122 (hereafter referred to as the catch-release buttons 122), so that the spring tension may be increased (to provide proper operation of the firearm 900 once the firearm magazine 102 is received by the firearm 900).

Generally, the spring-adjustment assembly 108 includes a series of tubes shaped according to the shape of the firearm magazine 102, with attachments to accommodate functionality, safety, and comfort of the user. The spring-adjustment assembly 108 provides, once assembled, a telescopic extension to the firearm magazine 102.

The spring-adjustment assembly 108 provides at least one or more benefits to a user of the firearm 900. Firstly, for instance, the ammunition may be loaded into the firearm magazine 102 in a relatively faster and/or more efficient way without the need for additional tools. Secondly, for instance, the spring-adjustment assembly 108 is coupled to the firearm magazine 102 while any one of the following conditions may exist (states of operation): (A) the firearm magazine 102 is operatively received in the firearm 900, or (B) the firearm magazine 102 is not operatively received in the firearm 900 (that is, the firearm magazine 102 is removed from the firearm 900). In this manner, the spring-adjustment assembly 108 is not inadvertently lost or misplaced. In sharp contrast, known ammunition loaders are very easily lost simply because these known devices do not remain (fail to remain) coupled to the firearm magazine 102 while the firearm magazine 102 is inserted into the firearm 900. For instance, if the firearm 900 is deployed during a firelight situation, the spring-adjustment assembly 108 allows for improved and convenient utilization of the firearm 900 under these extreme conditions.

Thirdly, for the case where it is required to (A) constantly hold the ammunition inside the firearm magazine 102 until required on a standby basis (such as, military application and/or law enforcement application, etc.), and/or (B) store the firearm 900 and the firearm magazine 102 until required (for instance, when the user is off duty or on leave, etc.). In this case, the spring-adjustment assembly 108 causes the ammunition spring 106 to be conveniently decompressed, and, therefore, the life and durability of the ammunition spring 106 may be significantly prolonged as a result of utilizing (employing) the spring-adjustment assembly 108.

Fourthly, where permitted by law, and/or where necessary, the spring-adjustment assembly 108 may be used as an ammunition-capacity extension. Therefore, a few more rounds of ammunition may be loaded, if so required or desired.

Fifthly (in accordance with an embodiment), a belt clip 138 (as depicted in FIG. 16) may be added to the spring-adjustment assembly 108, so there may not be a need for a magazine pouch for receiving the firearm magazine 102, and/or the firearm magazine 102 may be carried on a belt of the user, preferably without any additional equipment required for storage of the firearm magazine 102 (if so desired).

The firearm magazine 102 is combined with the spring-adjustment assembly 108 (also called an attachable telescopic spring decompression mechanism, or a spring decompression mechanism). The spring-adjustment assembly 108 is configured to provide firearm users with a relatively safer and relatively faster ability for loading ammunition into the firearm magazine 102, especially so for environments where speed and efficiency matters (and no other ammunition loading devices are readily available).

Preferably, the spring-adjustment assembly 108 is permanently attached to the firearm magazine 102. In this manner, the spring-adjustment assembly 108 cannot be misplaced or lost (this reduces or eliminates the need to carry additional ammunition-loading tools, such as speed loaders, etc.).

Once the firearm magazine 102 is fully removed from the firearm 900, and with the press of a button (by the user), a portion of the spring-adjustment assembly 108 extends downwardly from the firearm 900, thereby releasing tension of the ammunition spring 106 allows the user to (A) insert ammunition into the firearm magazine 102 relatively easier and/or relatively faster, with less possibility for inadvertently hurting (pinching) the fingers of the user, and (B) fill the firearm magazine 102 to fullest capacity possible. Preferably, in many cases, by using the spring-adjustment assembly 108, the loading of the firearm magazine 102 is not performed without some sort of ammunition loading device (known and not depicted), preferably to a full capacity of the firearm magazine 102 (if desired).

After the ammunition (the bullets 902) is loaded into the firearm magazine 102, the spring-adjustment assembly 108 is pushed (movable) upwardly from the bottom of the firearm magazine 102. This is done in such a way that tension is applied to the ammunition spring 106, and the ammunition spring 106 is returned to the required spring tension for proper operation of the firearm 900 (once the firearm magazine 102 is loaded into the firearm 900).

Referring to the first embodiment (as depicted in FIGS. 3 to 15) and also referring to the second embodiment (as depicted in FIGS. 16 to 21), the apparatus includes (and is not limited to) a synergistic combination of a firearm magazine 102, an ammunition spring 106 and a spring-adjustment assembly 108.

The firearm magazine 102 is configured to be selectively securely receivable (directly or indirectly) by the firearm 900. The firearm magazine 102 is also configured to be selectively removable (directly or indirectly) from the firearm 900. The firearm magazine 102 defines, at least in part, an internal well 104. The internal well 104 is configured to receive a plurality of bullets 902 therein.

The ammunition spring 106 is received, at least in part, in the internal well 104 of the firearm magazine 102. The ammunition spring 106 is in contact, at least in part, (either directly or indirectly) with a magazine floor 103 of the internal well 104 of the firearm magazine 102. The ammunition spring 106 is configured to apply pressure to (either directly or indirectly) the plurality of bullets 902 received in the internal well 104. This is done in such a way that the ammunition spring 106, in use, pushes against (directly or indirectly) the magazine floor 103 and urges (either directly or indirectly) the plurality of bullets 902 towards the internal well 104 of the firearm magazine 102.

The spring-adjustment assembly 108 is configured to: (A) selectively compress (directly or indirectly) the ammunition spring 106, and (B) selectively decompress (directly or indirectly) the ammunition spring 106 relative to the magazine floor 103 of the firearm magazine 102. The spring-adjustment assembly 108 is also configured to selectively decompress (directly or indirectly) the ammunition spring 106. This is done in such a way that a bullet 902 is relatively easier to insert in the internal well 104 of the firearm magazine 102 once: (A) the firearm magazine 102 is selectively removed (directly or indirectly) from the firearm 900, and (B) the spring-adjustment assembly 108 has selectively decompressed the ammunition spring 106. The spring-adjustment assembly 108 is configured to selectively compress (either directly or indirectly) the ammunition spring 106. This is done in such a way that the ammunition spring 106 provides relatively more pressure (directly or indirectly) against the plurality of bullets 902 housed in the firearm magazine 102, and the ammunition spring 106 urges (directly or indirectly) the plurality of bullets 902 towards the internal well 104 of the firearm magazine 102. The spring-adjustment assembly 108 is securely affixed (directly or indirectly) to the firearm magazine 102 while the firearm magazine 102 is selectively securely received (directly or indirectly) by the firearm 900. The spring-adjustment assembly 108 is securely affixed (directly or indirectly) to the firearm magazine 102 while the firearm magazine 102 is selectively removed from the firearm 900.

A technical advantage of the apparatus is that the user is not able to misplace the spring-adjustment assembly 108 because the spring-adjustment assembly 108 remains securely coupled to the firearm magazine 102, whether the firearm magazine 102 is received by, or is not received by the firearm 900. In this manner, the firearm magazine 102 may be refilled with fresh bullets 902 at any time by the user, as needed, simply because the spring-adjustment assembly 108 remains with the firearm magazine 102 at all times.

In sharp contrast to the apparatus, the prior-art ammunition loader systems may be easily lost or misplaced, and the user may then be required to manually insert the bullets 902 into the firearm magazine 102, which is not convenient for the user and/or the user may become inadvertently hurt while loading the firearm magazine 102 by using the prior-art ammunition loader systems.

In view of the foregoing (in summary), the firearm magazine 102 is configured to be selectively received by, and coupled to, the firearm 900. The ammunition spring 106 is received, at least in part, in the firearm magazine 102. The spring-adjustment assembly 108 is mounted to the firearm magazine 102, and the spring-adjustment assembly 108 is also interactable with the ammunition spring 106 once (A) the firearm magazine 102 is received by, and coupled to, the firearm 900, and (B) the firearm magazine 102 is removed from the firearm 900. The spring-adjustment assembly 108 remains with the firearm magazine 102 so that the spring-adjustment assembly 108 is not inadvertently lost or misplaced once the firearm magazine 102 is removed from the firearm 900.

In accordance with an embodiment, the spring-adjustment assembly 108 is interactable with the ammunition spring 106 once the firearm magazine 102 is removed from the firearm 900. This is done in such a way that the spring-adjustment assembly 108 selectively decompresses the ammunition spring 106 so that a bullet 902 is relatively easier to insert into the firearm magazine 102. The spring-adjustment assembly 108 selectively compresses, in use, the ammunition spring 106 so that the bullet 902 received by the firearm magazine 102 is ready for utilization by the firearm 900 once the firearm magazine 102 is received by, and coupled to, the firearm 900.

In accordance with an embodiment, there is provided a method for using the firearm magazine 102 configured to be selectively received by, and coupled to, the firearm 900, and in which the ammunition spring 106 is received, at least in part, in the firearm magazine 102. The method includes (and is not limited to) mounting a spring-adjustment assembly 108 to the firearm magazine 102 so that the spring-adjustment assembly 108 is interactable with the ammunition spring 106 once the firearm magazine 102 is received by, and coupled to, the firearm 900, and once the firearm magazine 102 is removed from the firearm 900. The spring-adjustment assembly 108 remains with the firearm magazine 102 so that the spring-adjustment assembly 108 is not inadvertently lost or misplaced once the firearm magazine 102 is removed from the firearm 900.

In accordance with an embodiment, there is provided (for the retrofit market) the apparatus, in which the apparatus includes (and is not limited to) a spring-adjustment assembly 108 configured to selectively reduce spring tension of an ammunition spring 106 of a firearm magazine 102 of a firearm 900 (this is done in such a way that the spring-adjustment assembly 108 permits relatively easier loading of ammunition into the firearm magazine 102. The spring-adjustment assembly 108 is mountable to the firearm magazine 102 in such a way that the spring-adjustment assembly 108 is not removable from the firearm magazine 102 once the firearm magazine 102 is securely coupled to the firearm 900.

Referring to the embodiments as depicted in FIGS. 3, 4, 5 and 6, the firearm magazine 102 includes (defines) an ammunition portal 105 (also called a first open-end section), and also defines a spring portal 107 (also called a second open-end section) that is spaced apart from the ammunition portal 105. The ammunition portal 105 is configured to receive a bullet 902 (as depicted in FIG. 6). This is done in such a way that the bullet 902 may enter an internal well 104 extending through the firearm magazine 102. The internal well 104 extends between the ammunition portal 105 and the spring portal 107. In addition, the ammunition portal 105 is also configured to provide (dispense) the bullet 902 from the internal well 104 to the firearm 900 (as depicted in FIG. 14). The spring portal 107 is configured to receive the ammunition spring 106 (as depicted in FIGS. 4 to 6).

The firearm magazine 102 includes a lip portion 109 (also depicted in FIG. 9) that is positioned proximate to the spring portal 107. The lip portion 109 may be called a peripheral edge. The lip portion 109 extends externally from the firearm magazine 102 (away from the interior of the internal well 104).

The spring-adjustment assembly 108 includes a first section 110 and a second section 112 that are configured to be (A) selectively movable relative to each other, and (B) selectively securely lockable to each other. The first section 110 may be called a first housing or a top housing. The second section 112 may be called a second housing or a bottom housing.

The first section 110 is configured to slide onto the firearm magazine 102 from a top section of the firearm magazine 102 toward a bottom section of the firearm magazine 102. The first section 110 defines a channel 117 (also depicted in FIG. 9) extending therethrough (that is, the channel 117 extends through the first section 110, between opposite ends of the first section 110). The first section 110 includes an edge portion 115 (also depicted in FIG. 9) extending into the interior of the channel 117 (that is, extending into the interior of the first section 110). The channel 117, defined by the first section 110, is configured to slidably receive the firearm magazine 102, and this is done in such a way that the first section 110 is movable from the ammunition portal 105 to the spring portal 107 of the firearm magazine 102.

As depicted in the embodiment of FIG. 5, the lip portion 109 (of the firearm magazine 102) eventually makes (is configured to make) interference contact with the edge portion 115 (of the first section 110) once the first section 110 is moved along an exterior surface of the firearm magazine 102 from the ammunition portal 105 to the spring portal 107. The first section 110 is no longer movable toward the spring portal 107 once the lip portion 109 makes interference contact with the edge portion 115.

The spring-adjustment assembly 108 also includes the second section 112. The second section 112 is configured to receive and to support an end portion of the ammunition spring 106 (as depicted in FIGS. 4 to 6).

Referring to the embodiment as depicted in FIG. 6, the first section 110 and the second section 112 are selectively coupled (either directly or indirectly) to each other. This is done in such a way that the first section 110 and the second section 112 are not movable relative to each other.

Referring to the embodiment as depicted in FIGS. 7 and 8, the firearm magazine 102 has been loaded with a plurality of bullets 902 (manually by the user by way of the ammunition portal 105). Since the spring tension in the ammunition spring 106 is relaxed as a result of using the spring-adjustment assembly 108 (as depicted in FIG. 12), the user may have a relatively easier time of inserting the bullet 902 into the firearm magazine 102. The firearm 900 includes, for instance, a pistol 905 having a downwardly-extending handle 903, etc. Returning to FIGS. 7 and 8, the firearm magazine 102 is configured to be securely received into the downwardly-extending handle 903 of the pistol 905, and to be selectively removable from the downwardly-extending handle 903. The ammunition spring 106 contacts the bottom-most bullet 902 and also contacts the second section 112 of the spring-adjustment assembly 108. The ammunition spring 106 biases the plurality of bullets 902 toward the ammunition portal 105 in such a way that the bullets 902 may be fed into the firearm 900 (on an as-needed basis) once the firearm magazine 102 is operatively received in the downwardly-extending handle 903 (as depicted in FIG. 8).

Referring to the embodiments as depicted in FIGS. 9 and 10, the spring-adjustment assembly 108 includes the first section 110 (as depicted in FIG. 9), and the spring-adjustment assembly 108 includes the second section 112 (as depicted in FIG. 10). The second section 112 includes a synergistic combination of a first hollow tube 118, a second hollow tube 130, a post member 134, and a receiver section 119. The first hollow tube 118 is configured to be slideable into the interior of the first section 110 (as depicted in FIG. 9). The first section 110 defines a pair of spaced-apart first engagement grooves 111 (hereafter referred to as the first engagement groove 111) that are formed in the channel 117. The first engagement grooves 111 are formed in the interior of the first section 110. The first engagement grooves 111 are configured to interact with a pair of oppositely-positioned rail elements 128 (hereafter referred to as the rail elements 128 or also called a slide rail, etc.) provided by the first hollow tube 118 (as depicted in FIG. 10). This is in such a way that the first hollow tube 118 is slideable (up or down) along the interior of the first section 110.

Referring to the embodiment as depicted in FIG. 9, the first section 110 also defines a retention cutout 114. The retention cutout 114 is configured to cooperate with a retention clip 116 of the first hollow tube 118 of the second section 112 (as depicted in FIG. 10). This is done in such a way that the first section 110 is selectively lockably engageable with (and disengageable from) the first hollow tube 118. The retention cutout 114 and the retention clip 116 are configured to selectively engage with each other (this is done in such a way that the first section 110 is securely coupled to the first hollow tube 118).

Referring to the embodiment as depicted in FIG. 9, the first section 110 also provides a pair of oppositely-positioned covers 129 (hereafter referred to as the covers 129) that are positioned on opposite lateral sides of the first section 110.

The protrusions 132 are positioned on opposite sides of the second hollow tube 130. The first hollow tube defines a pair of oppositely-positioned interior facing grooves 131 (hereafter referred to as the grooves 131) that are positioned on opposite sides of the first hollow tube 118. The protrusions 132 are slide engageable with the grooves 131 of the first hollow tube 118. Preferably, the rail element 128 and the grooves 131 are aligned against each other.

Referring to the embodiment as depicted in FIG. 10, the second section 112 includes the post member 134. The post member 134 is configured to be slidable along the interior of the second hollow tube 130. The post member 134 provides the magazine floor 103 (spring floor). The magazine floor 103 is configured to be movable in such a way that the magazine floor 103 compresses the ammunition spring 106 once the second section 112 is pushed upwardly. The magazine floor 103 is configured to be movable in such a way that the magazine floor 103 decompresses the ammunition spring 106 once the second section 112 is pushed downwardly (in an extended position).

Referring to the embodiment as depicted in FIG. 10, the second section 112 includes the receiver section 119. The receiver section 119 defines a bottom wall 133 surrounded by a peripheral side wall 135. The receiver section 119 defines an open top section configured to receive, at least in part, the post member 134.

The second section 112 provides a post attachment 136. The post attachment 136 is configured to securely attach to the post member 134.

The catch-release buttons 122 of the first hollow tube 118 are configured to interact (that is, latch to, and de-latch from) the retention openings 126 defined by the catch-release button housings 124 provided by the second section 112. For the case where the catch-release buttons 122 are latched (selectively connected) to the retention openings 126 defined by the catch-release button housings 124, the ammunition spring 106 becomes (and stays) compressed. For the case where the catch-release buttons 122 are de-latched (selectively disconnected) from the retention openings 126 defined by the catch-release button housings 124, the ammunition spring 106 becomes (and remains) compressed.

The receiver section 119 defines a pair of oppositely-positioned second engagement grooves 113 (hereafter referred to as the second engagement grooves 113). More specifically, the peripheral side wall 135 defines the second engagement grooves 113 that are each placed on opposite sides of the peripheral side wall 135. The second engagement grooves 113 are configured to slidably receive, at least in part, the rail elements 128 of the first hollow tube 118.

Referring to the embodiments as depicted in FIGS. 11 and 12, the firearm magazine 102 has been disconnected or removed from the firearm 900 (as depicted in FIG. 7). The first section 110 and the second section 112 are positioned in a spring-decompression position, in which the ammunition spring 106 is placed in a relatively decompressed state. In the spring-decompression position, the catch-release buttons 122 have been selectively de-latched (selectively disconnected) from the retention openings 126 defined by catch-release button housings 124 (as depicted in FIG. 10), and the second section 112 has been moved away from the first section 110 (this is done in such a way that the components of the second section 112 are not covered and may be accessible to the user). This is done in such a way that, in the spring-decompression position, the first section 110 and the second section 112 are spaced apart from each other. In the spring-decompression position, the user may insert the bullet 902 into the ammunition portal 105 of the firearm magazine 102 with relative ease and comfort (as depicted in FIG. 12).

Referring to the embodiment as depicted in FIGS. 13 and 14, the first section 110 and the second section 112 are positioned in a spring-compression position, in which the ammunition spring 106 is placed in a relatively compressed state (in comparison to, or relative to, the spring-decompression position as depicted in FIGS. 11 and 12). As depicted in FIG. 13, the firearm magazine 102 is disconnected or removed from the firearm 900. In the spring-compression position, (A) the catch-release buttons 122 have been selectively latched (selectively connected) to the retention openings 126 defined by the catch-release button housings 124 (as depicted in FIG. 10), and (B) the second section 112 has been moved toward the first section 110 (this is done in such a way that the components of the second section 112 are covered and not accessible to the user). This is done in such a way that, in the spring-compression position, the first section 110 and the second section 112 are relatively closer to each other (preferably, in direct contact with each other). In the spring-compression position, the user will find it relatively more difficult to attempt to insert the bullet 902 into the ammunition portal 105 of the firearm magazine 102 (for the case where the firearm magazine 102 is disconnected from the firearm 900, as depicted in FIG. 13).

As depicted in the embodiment of FIG. 14, the firearm magazine 102 is inserted into the firearm 900, and the firearm magazine 102 is configured to dispense the bullet 902 into the interior mechanisms of the firearm 900, with assistance from the ammunition spring 106.

Referring to the embodiment as depicted in FIG. 15, the ammunition limiter 120, in use, limits the number of bullets 902 that are received in the firearm magazine 102.

The connector 150 is configured to securely connect the base assembly 146 to the plate assembly 148. The footing 140 and the base assembly 146 are configured to house the latches 142 that are positioned on opposite sides of the footing assembly 140. The spring assembly 144 is positioned between the latches 142. The spring assembly 144 is configured to urge the latches 142 toward a latched position, in which the first section 110 remains securely connected with the footing assembly 140. To disconnect the first section 110 from the footing assembly 140, the user depresses the latches 142 in such a way that the spring assembly 144 no longer urges the latches 142 toward an un-latched position, in which the first section 110 may then be movable away from the footing assembly 140.

Referring to the embodiment as depicted in FIG. 20, the firearm magazine 102 has been disconnected from the firearm 900. The first section 110 has been de-latched from the footing assembly 140, in which the ammunition spring 106 becomes decompressed (so that a bullet 902 may be inserted into the interior of the firearm magazine 102). The post member 134 remains connected with the footing assembly 140. The magazine floor 103 of the post member 134 remains slide coupled with the second hollow tube 130. It is preferred that the user does not de-latch the first section 110 from the footing assembly 140 while the firearm magazine 102 remains operatively received in the firearm 900 (as depicted in FIG. 18).

Referring to the embodiment as depicted in FIG. 21, the first section 110 has been latched to the footing assembly 140, in which the ammunition spring 106 becomes compressed within the firearm magazine 102.
