  • Publication number: 20230349655
    Abstract: This disclosure concerns a pistol having an anti-disassembly protection device, which includes a disassembly key arranged rotatably in a frame, and which can be manually turned between an angular locking position and an angular disassembly position, and which disassembly key may occupy a transverse resting position and a transverse rotation position. The disassembly key has blocking means that cooperate with additional blocking means on the frame in order to prevent rotation of the disassembly key into the angular disassembly position when the disassembly key occupies the transverse resting position.

  • Publication number: 20230288158
    Abstract: The present disclosure relates to an unlocking mechanism for a pistol magazine. Each of two release buttons is fastened to one end of a release lever controlling the translation of a lock cam arranged at the front or back of the handle. The lock cam includes a lock cooperating with an abutment surface arranged on the front or back surface of the magazine. A spring holds the lock cam in the lock position in the absence of pressure on the release button. Each release lever has a lug bearing on a corresponding lock cam lug of the lock cam. The lock cam is translated when one of the release buttons is actuated. The unlocking device has two release lever springs holding the release levers in the locked position, so as to make the left- and right-hand release buttons independent of each other.
