A bolt catch device is disclosed. The bolt catch includes a movable surface configured to be positioned within a weapon so as to conditionally engage a bolt so as to prevent the bolt from rechambering a next round from a magazine, a tip configured to, in response to a received force, cause the movable surface to move so as to release the bolt, and a spring engagement feature configured to be positioned within the weapon so as to receive a spring within the weapon, wherein the spring within the weapon is configured to bias the movable surface toward a position which prevents the bolt from rechambering a next round.

A magazine of a pistol for cartridges with a case rim, having a hollow magazine body for accommodating the cartridges in two vertically offset rows, a base plate, a feeder, which is guided in a displaceable manner in the magazine body, and a compression spring between the feeder and the base plate, wherein the upper end region of the magazine body forms a narrowing, in which the two rows of cartridges are guided together to form a single row. In order to ensure a reliable feed of the cartridges despite the case rim, in the longitudinal center the side walls have inwardly directed beads which run over the entire height of the side walls and merge, in the upper region, into converging guide ribs, and the feeder forms a bearing surface, which is convex in the longitudinal direction and on which a cartridge located thereon can alter its angle of inclination in relation to the horizontal.

A bolt for a bolt-action firearm in one embodiment is movably disposed in a receiver between forward closed breech and rearward open breech axial positions. The bolt includes an operating handle and plurality of bolt lugs arranged to selectively engage locking lugs in the firearm. The bolt is rotatable between locked and unlocked breech positions when in the closed breech position. The bolt body has a dimensionally reduced middle section with unique configuration adapted to allow the bolt to rotate when closed without interference from the magazine feed lips. Using this design, the bolt may include three bolt lugs in one embodiment for secure lockup and minimal angular rotation between the locked and unlocked breech positions. The bolt is usable with both single and double stack box type magazines with one of the bolt lugs operating to reliably strip cartridges from either type magazine.

The barrel of a pistol, specifically in a short recoil operated pistol, is comprised of multiple bearings surfaces comprised of cams and lugs that allow the pistol to function. The surfaces mechanically delay the pistol enough to allow the pistol to reliably function in the manner of an automatic firearm, chambering a round at the end of each cycle of operation. A barrel that locates a forward lug positioned horizontally in front of the trigger guard of the pistol with side cams that are shallow and interact in a way to provide the pistol with a robust and consistent lock up from shot to shot to provide an advantage in the function of the firearm.
