What are these 4 rules ?
The 4 cardinal firearm safety rules as I teach them:
1. Keep your finger off the trigger until your sights are on the target and you have made the decision to fire.
2. Do not point your gun at anything you are not willing to destroy.
3. Treat all guns as if they are always loaded.
4. Be sure of your target and what is around and beyond it.
They are slight modifications of Cooper's 4 rules.
