SELF-LOADING PISTOL Russian patent published in 1999 - IPC

FIELD: small-arms weapon. SUBSTANCE: self-loading operates on the principle of use of recoil energy at a short stroke of the barrel, engagement of the barrel with the slide at the instant of fire is accomplished by the barrel latch, which at the same time serves as a barrel recoil accelerator. The slide has a lug, and the barrel latch has a chamfer, which are engageable at the instant of turning of the latch at unlocking of the bore in recoil. The slide gets an additional acceleration at backward motion. EFFECT: enhanced reliability, especially in difficult conditions, at heavy fouling due to the increase of kinetic energy of the movable parts providing for acceleration of the slide recoil. 3 cl, 3 dwg
