HOW TO USE YOUR FIREARMRemove the magazine from the pistol by depressing the magazine release button (Fig. 1).
Loading the magazine:
Hold the magazine with one hand, and with the other push down the feeder platform or the round already
in the magazine and carefully slide the new cartridge completely back under the lips. Repeat this proce-
dure until the magazine is fully loaded.
Damaged or bent magazine lips may cause malfunctions. Do not use force.
Loading the cartridge chamber:
Before loading, be sure the muzzle is pointed in a safe direction. Insert the fully loaded magazine into
the pistol. Hold the firearm with one hand, and with the thumb and index fingers of the other hand grasp the
serrated sides of the slide and pull it back (Fig. 2), then release the slide.
The firearm is now loaded and ready to fire.
Caution: Always keep your finger off the trigger whenever you do not intend to fire.
Safety:
Engage the manual safety by pushing it up (Fig. 3). This movement disengages the connection between
the trigger and the hammer.
Decock the hammer and block the slide. The red warning dot then disappears.
