We gun people don't read. We shoot.
Remember, though, "All guns are always loaded," "keep your finger off the trigger until you are ready to fire," and "never cover anything with the muzzle you wouldn't be willing to shoot."
Excellent. Three of the four rules. Those will usually get you by OK, but don't forget "be sure of your target, and what is beyond it".
Edit: Oops, should have read the second page, but you still can't point this stuff out too much.
