ABSTRACT:
The gun can be switched to operate either in a double action or as single mode. A pin located in the slide can be rotated from a position, in which a jacket surface is flush with the bottom surface of the slide to a position where a nose projects above the bottom surface of the slide. The sear has a control cam which is acted upon by the nose of the pin when in its projecting state. The hammer includes a detent member having two abutment shoulder sections adapted to cooperate with a control edge of the sear. If the pin is in a position, in which mentioned jacket surface is flush with the bottom surface of the slide, it does not act upon the control cam of the sear such that upon the loading or a firing of the gun, the hammer is held in the fully cocked position, in that the first control edge of the sear engages the forward abutment shoulder section of the detent member. This is the single action mode. If the nose of the pin projects over the bottom surface of the slide, it depresses the control cam of the sear during the forward movement of the slide after having recoiled such that the control edge of the sear engages the second abutment shoulder section of the detent member of the hammer, wherewith the hammer is held in a precocked position and must be cocked firstly before firing a subsequent shot. This is the double action mode.
