It should be noted that AZ self defense law requires you to use the same type of weapon as your attacker. For instance, if you shot someone attacking you with a bat, it would likely not be self defense.

It has been broadened recently since it used to require exactly the same weapon, so if someone was attacking you with an uzi, you couldn’t defend yourself with your shotgun. However I’m fairly certain it still won’t let you stab someone trying to fistfight you.
