Abstract: A handgun has a grip portion defining a magazine well, the grip portion having a web region configured to be grasped between a thumb and an index finger, a forward portion of the web region defining a first width. The grip portion also has a palm region configured to be grasped by a user's palm, the palm region defining a second width greater than the first width. A magazine is configured to be received in the magazine well and includes a hollow magazine tube with a single-stack portion and a double-stack portion positioned below the single-stack portion. For example, front portions of the opposite tube sidewalls have a stepped shape between the upper tube end and the double-stack portion.

Abstract: A detachable box magazine for firearms includes a hollow magazine tube extending longitudinally along a median plane. The magazine tube defines a single-stack portion extending substantially to an upper tube end that defines an upper tube opening. The magazine tube has a double-stack portion positioned below the single-stack portion and extending to a bottom tube end. For example, front portions of the opposite tube sidewalls have a stepped shape between the upper tube end and the double-stack portion, and the rear portions of the sidewalls have a linear taper between the upper tube end and the double-stack portion.

Abstract: A receiver assembly for a rifle includes a receiver with a feed assembly configured for open-bolt operation. A feed cover is hingedly mounted to the receiver and includes a portion of the feed assembly, where the feed cover is movable between a closed position and an open position by pivoting about a hinge pin oriented along a longitudinal axis of the receiver. For example, the feed cover can pivot to one side of the receiver when in the open position. A rifle incorporating the receiver assembly is also disclosed.

Abstract: A takedown lever assembly for a striker-fired handgun. The takedown lever assembly includes a takedown actuation lever operable between a firing position and a takedown position, and a safety bar operatively coupled to the takedown actuation lever. The safety bar moves longitudinally along the frame in response to moving the takedown actuation lever from the firing position to the takedown position, thereby causing the sear to disengage from the striker.

Abstract: A handgun grip module includes a body portion extending longitudinally with a first body sidewall, a second body sidewall spaced from the first body sidewall, and a bottom body portion extending between and connecting the first body sidewall and the second body sidewall. The body portion has a distal body portion defining a recoil spring channel and a proximal body portion defining a frame box. A recoil block in the body portion is positioned between the recoil spring channel and the frame box and extends laterally between the first body sidewall and the second body sidewall. The recoil block has a distal face and a proximal face. A metallic bracket is disposed against the distal face of the recoil block. A handgrip portion extends transversely down from the body portion and defines a magazine well extending therethrough to the frame box.
