The arm is loaded by pushing back the magazine catch in the bottom of the butt at the rear, which releases the standard steel box magazine to be withdrawn through the bottom of the grip section of the receiver. The magazine is loaded by pressing the first cartridge down on the front end of the magazine platform (or follower) and pushing it back under the overhanging lips of the magazine. Succeeding cartridges are started by forcing each one down on top of the one below it until the cartridge column is depressed enough that the cartridge may be slid back under the lips which overhang part of the top of the magazine to retain it. The loaded magazine is then inserted in the butt and pushed until it locks.
The serrated sections at the rear of the slide are then gripped by the thumb and fingers of the left hand while the pistol is held in the right hand, care being taken to see that the firing finger is not inside the triggerguard. Drawing the slide back to its fullest extent compresses the recoil spring mounted about its guide in the receiver channel below the barrel, to provide energy for the return movement of the slide.
As the slide is drawn back, it pulls with it the striker which is mounted in the rear breechblock-section of the slide in line with the chamber. The spiral spring around the striker is compressed as the striker is withdrawn. The sear catches in the striker bent and holds the cocked striker in rear position. The spring in the magazine thrusting up against the magazine follower pushes the cartridges up, and as the solid breechblock section of the slide passes over the top of the magazine, the top cartridge can rise far enough to be in line with the breechblock when that unit goes forward.
Releasing the grip on the slide permits the recoil spring to pull the slide forward, and the feeding face on the breechblock, striking the top of the cartridge case in line, thrusts it forward out of the retaining lips of the magazine, and into the firing chamber. The extractor in the breechblock snaps over the cartridge case and engages in its extracting groove. The pistol is now ready to fire. There is a thumb-
piece on the side of the receiver on the left which may be pushed up to lock the action so that the trigger cannot release the striker. Unless this thumb safety is applied, the pistol is now dangerous. When the striker is cocked, its head protrudes through the rear of the slide. Thus, if a protrusion can be felt or seen, one is warned that the arm is cocked, though the chamber is not necessarily loaded.
With the safety off (in the "down" position) pressing the trigger will force back the trigger mechanism to free the striker pin and let its spring drive it forward to fire the cartridge in the chamber.
