Things You'll Need
Instructions
Push the magazine release button with your thumb, ejecting the empty magazine from the bottom of the lower receiver, or grip. The button can be found on the left side of the pistol, right behind the trigger guard.
Place a loaded magazine into the magazine well, located on the bottom of the grip. Push the magazine upward until it locks into place.
Press down the slide release switch on the left hand side of the weapon, just above where your thumb naturally rests on the grip. The slide will move forward, chambering a fresh round as it does. Your Glock pistol is now reloaded and ready to fire.
