A firing pin lock for firearms is provided. The firing pin lock is a single piece of resilient metal that includes a pocket for receiving the head of the firing pin to prevent inadvertent discharge of the firearm. The firing pin lock can be mounted laterally in the bolt carrier group and is deflected outwardly by the action of the hammer.

A rotating gun bolt assembly includes a main body subassembly and a head subassembly. The main body subassembly including a helical receiving pocket. The head subassembly includes a head end and a rear end. The rear end of the head subassembly includes a helical tang extending from the rear end and mated with the helical receiving pocket in the main body subassembly. The helical tang includes a straight side, a distal edge and a helical side. The straight side extends perpendicular from the rear end of the head subassembly. The distal edge extends perpendicular to the straight side, where the distal edge is parallel with the rear end of the head subassembly. The helical side extends helically from the rear end of the head subassembly to the distal edge of the helical tang.

A firearm includes a barrel having a breech end. A receiver is engaged with the breach end of the barrel and defines a chamber. A vent path is through the barrel downstream from the breech end. A latch is downstream from the vent path. A bolt is at least partially inside the chamber. The bolt has a locked position to prevent the bolt from moving away from the breech end of the barrel and a released position that allows the bolt to move away from said breech end of the barrel.

The present invention is directed to novel recoil inversion assemblies, which reduce recoil generated by blowback of the propellant gases, as well as their use in propellant-based projectile weapons. Such novel weapons afford reduced recoil, muzzle flip, and muzzle climb, and therefore exhibit improved manageability as compared with current related weapons, particularly when utilizing high powered ammunition. In particular, the recoil inversion assemblies of the present invention further comprise novel delayed-blowback assemblies affording utility with larger caliber ammunition.

A pistol may include a firing device arranged in a slide. The firing device includes a strikerhaving a striker head, characterized in that the device has at least two parallel striker springs arranged laterally on the side of the striker axis and bearing on at least two bearing surfaces arranged perpendicularly to the axis of the striker.

A firearm operating system includes a housing, a central pivoting member disposed within the housing, a trigger including a portion disposed within the housing and a portion extending outside the housing such that the portion of the trigger within the housing includes a hole and at least one finger that extends in a first direction from the hole. Due to movement of the trigger, the at least one finger presses against the central pivoting member to cause the central pivoting member to rotate.
