This individual was field stripping a Glock pistol, and Glocks require that you pull the trigger in order to separate the slide from the frame. He undoubtedly failed to clear the chamber and accidentally discharged the pistol into his hand. One of the issues that I’ve encountered in dealing with shooters and firearms, in both civilian and military settings, is that they become complacent in handling their weapon, and sometimes that familiarity breeds contempt – this is the result.

Undoubtedly, you’ve heard this repeatedly:

1. Always assume that a weapon is loaded.

2. Point the weapon in a safe direction and keep your finger off the trigger

3. Drop the magazine.

4. Lock the slide back, and visually, and physically inspect the breech.

5. After you’ve cleared the weapon, place the weapon down such that there is a clear view of the breech.

Now internalize it!
