A projectile entangling device, cartridge and method for entangling an object. The projectile entangling device comprises a bolt slidably engaging within a receiver. A barrel is coupled to the receiver and is adjacent to a chamber. A gas conduit couples a compressed gas container to the bolt. A valve is positioned within the gas conduit. A trigger activates the valve and dispensing a compressed gas from the compressed gas container, through the gas conduit and exits the bolt. A first projectile and a second projectile are positioned within the cartridge. A tether is coupled to the first projectile and the second projectile. The first projectile, the second projectile and the tether are propelled from the cartridge and expelled from the barrel upon the compressed gas exiting the bolt. The tether elongates for distancing the first projectile from the second projectile for defining an expanding projectile and entangling with the object.

A pistol has a bolt with a surface that contacts the cartridge in the magazine to next be chambered. The bolt is mounted within the slide. As the bolt moves with the slide out of battery the surface exerts a force on the cartridge in the direction of motion of the slide. The force counteracts inertial forces on the cartridge imposed by recoil of the pistol.

A firearm reload system that enables the reloading of a firearm with a single user action. The firearm reload system can include an automatic ammunition chambering system and an empty magazine auto-eject system. The automatic ammunition chambering system includes an actuator on a magazine that actuates a pivoting slide lock when the magazine is introduced into the firearm frame, causing the pivoting slide lock to disengage from the firearm's slide release, thereby freeing the slide and chambering a cartridge. The magazine auto-eject system includes a magazine actuator linking the slide release and the magazine release such that when the slide release is brought into a locked position, the magazine actuator actuates the magazine release such that the magazine is released from the firearm.

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.

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 magazine of a pistol for cartridges of the caliber .22LR with a case rim, consisting of a hollow magazine body for receiving the cartridges in two rows, a stub-like base plate, a feeder slidably guided in the magazine body, a compression spring between the feeder and the base plate, which base plate has a bore as do the two side walls of the magazine body comprise openings, all of which are formed by a transversely extending bolt, wherein the upper end region of the magazine body forms a constriction in which two rows of cartridges are brought together into one. The side walls have inwardly directed corrugations running longitudinally over their entire height, which merge with guide ribs in the upper region.
