The NRA has 3 primary rules:
1) ALWAYS Keep your gun pointed in a safe direction
2) ALWAYS Keep Your Finger Off The Trigger Until Ready To Shoot
3) ALWAYS Keep The Gun Unloaded Until Ready To Use
As long as you are following them, I don't think it matters how word it.
As evidenced by my avatar I'm an NRA instructor. I do not and never have agreed with the NRA's wording of the rules. (Three is especially offensive) When I teach a class I hand out the NRA rules handout and then I teach students the actual rules.
I prefer to go with the rules as set down by Cooper. Who, as the American Rifleman put it:
"Cooper single-handedly changed the entire methodology for small arms in all branches of the U.S. military. He modernized Applegate’s outmoded “hip shooting” and “point shooting” techniques with a thoroughly new method. In the process, he transformed law enforcement handgun training nationwide, from the FBI Academy to Mayberry RFD."
Every shooter has been influenced in some way by Col. Cooper.
Cooper may well have had quite an ego but he earned it. No other single person has had as much of an effect on the way military, law enforcement and civilians shoot handguns.
