US Patent 10209019 Pistol

A pistol with a frame, including a trigger mechanism and a movable slide, in which a barrel, a recoil spring, and a firing mechanism comprising a firing pin are located. The firing pin is movably mounted in a firing pin guide, where the firing pin guide has a holding plate on the end, which is pivoted in a holding notch in the slide, the slide being affixed in one angle of rotation of the holding plate and not in one other angle of rotation, and that the holding plate has a stop retainer, which abuts against a stop level in the frame and prevents the firing pin guide (spacer sleeve) and the firing pin from moving forward with the slide when the slide is removed from the frame.
