What is the first rule of gun safety?
It's likely always assume a gun is loaded.
Close to that would be don't point the gun at something you don't intend to kill.
Third would be keep your finger off the trigger unless you are about to fire.

first one is correct. Developed by the Marines in the 1800's.
I would amend the second line to are not willing to kill, as quite often the intent is to defuse the situation, and the third isn't really a rule but is a good adjunct. I have not memorized the rest of the list, as it's all clarification of the first rule. Such as be sure of your back drop, aim carefully, things like that.
I am happily surprised that someone was so quick with that. In the cities I've lived in, people come up with all kinds of really wacky stuff. The one I hear the most often is never point a gun at someone. That makes me nuts. In a SHTF situation, even just a personal one, you are of course HOPING to point your gun at the aggressor before they can do unto you.
Never met a country boy (or girl for that matter) who didn't know the rule.
I agree about the 2nd ... not willing as opposed to intend.
ps. I'm not a city boy. But I think I learned it in a NRA gun safety course at the store I bought my first pistol from.
