1. Load two rounds into the magazine.
2. While in a stable firing position point the muzzle downward.
3. Pull the charging handle or slide back, let it fly forward to chamber the first round.
4. If your weapon fires as soon as the round is chambered this is called slamfire. UNLOAD THE WEAPON IMMEDIATELY.
5. If there is no slamfire take the gun off of safety and pull the trigger.
6. If both rounds fire with one pull of the trigger this is called doubling.
7. Both of these situations are dangerous and are not correct operation of the gun. Make sure the gun is UNLOADED and take the gun to a gunsmith or place of purchase and have it fixed.
