The Definition of Three Rules
The NRA teaches the Three Basic Rules of Safe Gun Handling.
There are additional rules, but these are the three that if any two are followed, nobody will be hurt. However, obviously, all three should
always be followed.
Rule One: ALWAYS keep the gun pointed in a safe direction.
The NRA established these three rules in 1871. They were created to be easy to understand and remember,
ensuring the highest possible level of firearm safety.
Rule Two: ALWAYS keep your finger off the trigger until ready to shoot.
Rule Three: ALWAYS keep the gun unloaded until ready to use.
