SELF-LOADING PISTOL Russian patent published in 2014 - IPC F41C3/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention refers to armament, and namely to a self-loading pistol containing a barrel, a frame, a breech mechanism, a cartridge, a recoil spring, a recoil spring guide, a trigger, a sear, a release trigger, a safety lock and fire selector and a striker. Cocking of the trigger is performed by an external automatic safety lock at contact with a rifleman arm. The automatic safety lock is made in the form of a spring-loaded rocking lever with three projections. The first projection has the possibility of interaction with the trigger so that when the external automatic safety lock is offset through an angle that does not exceed more than 2/3 of the angle of its full stroke; the trigger is fully turned and engaged with the sear. When the external automatic safety lock is offset through an angle that does not exceed more than 1/3 of the angle of its full stroke, the second projection can contact the trigger so that the latter has no possibility of being turned through an angle required for contact with the striker. When the external automatic safety lock is offset through an angle that does not exceed more than 1/3 of the angle of its full stroke, the third projection can interact with the sear so that the latter is disengaged from the trigger.

EFFECT: increasing safety, improving actuation reliability and ease of arms handling.
