Automatic weapon with a combined system of use (alternatives)

An automatic handgun has an additional trigger mechanism and a sight. In one version, a draw bar in the butt is hinged to a rotatable fork and to the additional trigger, located on the left of the butt in an L-shaped groove. Upon rotating the fork the spring extends onto the left of the butt, and when the butt is closed onto a catch, the end of the fork grips the main trigger. Rotatable posts lie on the sight. Alternatively, a rotatable lever sits on the lower front of the breech. The lever has a post on which the additional trigger which fixes the horizontal and vertical positions is hinged, and is connected to the main trigger by a draw bar through the inside left of the breech. Shooting accuracy increases and the overall dimensions are reduced.
