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.

The present invention provides a pistol with a frame having a rear grip, a trigger facility forward of the grip and an upper surface. An elongated slide is connected to the frame and operable to reciprocate along the upper surface. The frame defines a rear recess open at the upper surface. An insert is included having a major portion removably received in the rear recess and having a frame rail extending from the major portion above the upper surface. The frame rail is adapted to connect with the slide to constrain reciprocation.

Provided is an automatic pistol comprising a frame with frame guides, a barrel arranged on the frame guides of the frame, a breech and a closing and locking device. The closing and locking device comprises a rod with a closing spring and further comprises a guide bushing, wherein the guide bushing is couplable to the rod and wherein the rod comprises lateral locking elements at its rear end. The frame also has symmetrically arranged inclined grooves designed to receive the locking elements of the rod, so that the rod is guided from an inclined position (locking position) to a horizontal position (unlocking position) and vice versa as a result of a shot from the gun.

Implementations of a stabilizing brace assembly for a firearm are provided. The stabilizing brace assembly is configured for use in attaching a forearm stabilizing brace to a pistol, thereby providing additional stability to a user aiming and firing the pistol. In some implementations, the stabilizing brace assembly is also configured to position an optical sight (e.g., a reflex type sight) so that it can be used to aim the pistol.

A slide for a semiautomatic pistol includes features that reduce weight while maintaining structural rigidity and performance of the slide. The semiautomatic pistol slide may include one or more weight-reducing recesses and a structurally supportive insert within each weight-reducing recess. Methods and systems for fabricating semiautomatic pistol slides and other articles of manufacture that include weight-reducing recesses with structurally supportive inserts therein are also disclosed. Such a method may include a compression molding technique. Such a system may include a compression molding assembly.

A striker assembly including a striker elongated along a striker axis, a sear member, and a stop element. The sear member is connected to the striker, extends outwardly from the striker axis, and is rotatable about the striker axis. The stop element is movable between at least a stop safety position and a stop firing position, wherein the stop element is positioned to inhibit the sear member from rotating about the striker axis when the stop element is in the stop safety position, and wherein the stop element does not inhibit the sear member from rotating about the striker axis when the stop element is in the stop firing position.

A recoil-operated pistol has an arrangement which lowers the barrel bore axis and reduces the effect of felt recoil on the user. The pistol has a frame having a handgrip adapted to receive a magazine and a slide mounted for alternating longitudinal movement. A barrel carrier is mounted for alternating longitudinal horizontal movement along the frame and has a barrel rotatably connected to it near its muzzle end. The axis of the barrel bore when in the position for firing is below the lips of the magazine. An actuating mechanism under the influence of the recoiling barrel carrier rotates the barrel upwards such that the breech end of the barrel moves upwards to allow a cartridge to be removed. The recoiling barrel carrier urges the slide rearwards to facilitate the extraction and feeding of cartridges.
