Provided is a mechanism for selectively preventing cycling of a semiautomatic handgun having a frame and a longitudinally reciprocating slide. The device includes a pivotal blocking lever on one of the slice or frame. The blocking lever is selectively movable between a first position that allows the slide to cycle when the handgun is fired and a second position in which a blocking member mechanically bridges between the frame and slide to block cycling movement of the slide when the handgun is fired.

A breech block with a bolt carrier, on which a bolt head and a locking device are arranged with two diametrically opposed locking elements pivotable from a release position to a locking position via a control element, for holding the bolt head in a locking position. The locking elements are mounted pivotably around a common transverse axis via journals and the control element contains front and rear support areas that abut against the locking elements for controlled forced movement of the locking elements into both the locking position and the release position.
