5. OPERATING PRINCIPLES

Prior to firing the pistol, the bolt is locked by three lugs in the barrel assembly. Upon firing the pistol, propellant gases pass through a hole underneath the bore of the barrel into the gas cylinder and push the piston, which in turn moves the slide backwards. During this movement the bolt is unlocked and carried to the rear by the slide, but not before, the pressure in the chamber is reduced. When the bullet has left the barrel the empty cartridge case is extracted and ejected by the continuing movement of the slide and the bolt to the rear. At the same time, the slide pushes the hammer downward into the cocked position, where it is retained by the sear. The recoil springs are compressed.
