The handle is made in form of a breechblock, separate from the case with a longitudinal elongated shell with a support for the firing finger, a figure retracting projection and a projection. The projection is moveably joined to the breechblock. On the breech end of the rotating breech slide there is a figure retractable projection. The figure retracting projection and projection, moveably joined to the breechblock, are inside a longitudinal slot, which is made in the wall of a lengthwise shell-type guide, reaching the breechblock lever. The shooting assembly is detachably joined to a counterrecoil mechanism. The lengthwise elongated shell and the lengthwise shell-type guide form a telescopic system of the breechblock, inside of which is put a slide spring. The joint between the support of the shooting finger and its lengthwise trigger guard is a sliding joint and provides for keeping the breechblock lever in a position for assembling and disassembling the weapon.
