It was intended to replace the costly Luger P08, the production of which was scheduled to end in 1942. The moving-barrel mechanism is actuated by a wedge-shaped hinged locking piece underneath the breech. When the pistol is fired, the barrel and slide recoil together, until the hinged locking piece drives down, disengaging the slide and arresting further rearward movement of the barrel. The slide continues its rearward movement on the frame, ejecting the spent case and cocking the hammer before reaching the end of travel.

Two recoil springs on either side of the frame and below the slide, having been compressed by the slide’s rearward movement, drive the slide forward, stripping a new round from the magazine, driving it into the breech and re-engaging the ba
