TAKE NOTE:
Always assume that the GLOCK pistol or any other firearm is loaded is capable of being discharged until you the user, have been personally convinced to the contrary.

When firing with a two hand grip, the thumb of the weak hand should be on the weak hand side of the firearm, never behind the slide.
