Abstract: An improved M1911 handgun is disclosed. The improved M1911 handgun contains a handle containing a lower end, and a magazine well formed in the handle and adapted to receive and hold a double stacked magazine, wherein the inner cross-sectional profile of the magazine well is same from the lower end of the handle to a top of a frame of the improved M1911 handgun.

Abstract: A rear sight assembly for a firearm is disclosed. The rear sight assembly contain a sight base coupled with the firearm, a sight blade pivotally coupled with the sight base and a tension member positioned between the sight base and the sight blade and configured to push the sight blade against the firearm.

Abstract: A magazine for use in a firearm includes first and second feed lips having folded portions to reinforce the strength of the respective feed lips. In some embodiments, the strength of the feed lips may be further reinforced by applying one or more welds. The feed lips are capable of withstanding greater amounts of force to avoid failure. Accordingly, the disclosed magazine and method for providing the magazine reduce the “spring back” effect present in conventional magazine feed lips. This removes the additional step of having to over-form the feed lips that is performed when forming a magazine having conventional feed lips. The result is a method for providing a magazine with folded feed lips that are capable of withstanding greater amounts of force to avoid warping, deforming, or other failure, wherein the method for forming the magazine is more accurate, more consistent, and involves fewer steps.

Abstract: A magazine for a firearm is formed by a magazine box with a spring therein. A magazine follower in the magazine box is urged toward an open end thereof by the spring, and is formed by a base member extending along a longitudinal axis of the magazine box, and slide stop actuating and cartridge engaging structures extending outwardly from the base member. The slide stop actuating and/or the cartridge engaging structures are resiliently biased in a lateral direction away from a longitudinal axis of the base member to be movable between: (1) a compressed position wherein a longitudinal axis of the slide stop and/or the cartridge engaging structures are laterally perpendicular with the longitudinal axis of the base member, and (2) an uncompressed position where the longitudinal axis of the slide stop actuating and/or the cartridge engaging structures are not laterally perpendicular with the longitudinal axis of the base member.

Abstract: A magazine for use in a firearm includes a housing defining an interior portion for housing one or more cartridges. A first feed lip is coupled to a first side of the housing and is operable to retain the one or more cartridges. The first feed lip includes a first arcuate portion extending from the housing and toward a centerline of the housing, and a second arcuate portion extending from the first arcuate portion and back toward the first side of the housing. A second feed lip is coupled to a second side of the housing and is operable to retain the one or more cartridges. The second feed lip includes a first arcuate portion extending from the housing and toward the centerline of the housing, and a second arcuate portion extending from the first arcuate portion and back toward the second side of the housing.

Abstract: A fiber optic sight for a gun is disclosed that allows for increased illumination to the shooter's eyes by the use of an angled cut at the forward end of the fiber optic rod. The angled cut is positioned on the underside of the rod, and the fiber optic rod is exposed to the ambient light through the exterior surface of the rod onto the angled cut. The angled cut may be polished or be provided with a reflective surface that may be applied to, bonded to or positioned adjacent to the angled cut. The ambient light is directed along the major axis of the fiber optic rod towards the shooter's eyes. A reflector may also be positioned against the angled cut to enhance the reflectivity down the major axis of the fiber optic rod. The illumination may be further increased through the positioning of a light source alongside the fiber optic rod, with the light being directed onto the angled cut, and along the major axis of the fiber optic rod.

Abstract: A latch for mounting a suppressor to a firearm is disclosed that allows interfacing with and securely attaching to the weapon's flash hider without the need to use threads and the rotational movement commonly associated with attaching suppressors to a firearm. The latch consists of a primary latch and a secondary latch. The primary latch moves in a vertical plane, fits into the grooves on a standard flash hider, and is rotationally indexed to the flash hider when locked. The secondary latch attaches to the top of the primary latch, securing the primary latch when it is fully locked by pivoting around and downwards, and locking to the suppressor. The primary latch compensates for the considerable tolerance range of the outside diameter of the flash hider. The latch has minimal thermal coupling to the suppressor and engaging/disengaging the primary latch plate and the secondary latch can be accomplished with one hand.

Abstract: A trigger system for an automatic handgun includes a trigger bar sized to be installed in an interior space behind a trigger by movement from the magazine well. The trigger bar is first inserted into the inlet opening of the magazine well and into the interior space which includes a front cavity having a pair of spaced apart upper shoulders and lower shoulders that limit movement of the trigger bar upwardly and forwardly respectively. The interior space further includes a rear cavity that includes a pair of spaced apart lower ledges and a pair of spaced apart rear walls for limiting the rearward and downward movement of the trigger bar. The front cavity is adjacent the trigger and trigger guard. The rear cavity is formed within the handgrip. The trigger system and method is specifically designed for a Colt 1911 .45 pistol with an enlarged magazine well inlet opening for receiving an enlarged stagger magazine.
