- 1). Always assume that the gun is loaded; point away and in a safe direction to unload the weapon. Remove the magazine from the gun, then slide back, making absolutely sure that the Glock is emptied. Place the gun away from your work area.
- 2). Put on your safety goggles and turn your magazine upside down so that the floor plate is facing upward. Using your punch (or if you have the Glock armorer's tool you can use that), insert that punch into the hole, pushing the tab down and into the magazine.
- 3). There are locking tabs on both sides of the magazine. With your thumb and finger, grab and apply pressure to these tabs, while pulling forward on the punch. Remember, there is a plate being pushed by a spring underneath the floor plate, so be extremely careful when you slide the floor plate off; keep your other thumb over the opening so the spring does not fly out of the magazine.
- 4). Remove the retention plate and spring from the magazine, remove the follower (the plastic piece at the bottom of the spring) from the spring and set all the pieces aside. Spray a little CLP gun cleaner on each piece and scrub it with your brush. After you scrub these pieces down, wipe them clean with your cloth, making sure all the leftover cleaner is removed.
- 5). Reassemble the magazine---put the spring back on the follower, drop the follower into the magazine (it will only go in one way), put the retention plate in, keeping your thumb on this piece so that the spring does not fly out of the magazine, and slide the floor plate back into place.
