I'm tired of the safety rules made up by each person ( Check it twice, rack it three times, etc. ) .
Pulling the trigger without the muzzle pointed at a safe backstop ( box of phone books, body armor, sand barrel etc. ) violates Rule #1 and Rule #2 of Cooper's Rules ---Period !
To unload, with finger up on frame off the trigger, remove the mag, rack the slide twice and lock it open, visually and physically check the chamber and the rest of the interior of the gun for any rounds stuck inside .
To store the gun, let the slide forward, finger still off the trigger . Point it at a safe backstop and pull the trigger if you want to . If it leaves your hands, re-check it before dry snapping .
To hand a gun to someone else, hand it over open and empty and pointed in a safe direction .
