On the range no issue. Shoot em (or not if you forgot it's on safe), open gun, kick em out. Turn, step off station. Hunting and you actually remembered to push it off, if there's no shot, there's also no liklihood of opening the gun so it isn't going to reset itself. Pumps ain't got one nor autoloaders. m12 the only thing I can hit a bird with so it behooves me to remember to push it off (good place to have forefinger also), take shot (or in my case usually two) or not, raise muzzle in air, get finger out of triggerguard, push on with left thumb. I doubt I've seen every conjunction of circumstance and distraction but in every situation the direction of muzzle, awareness of position of safety, and the responsibility for disposition of chambered shells comes first.
