I would guess a pump will hiccup, but autos hiccup more often at the shoots I have attended..
I've seen more guys short stroke a pump action during timed drills than I've seen semi-auto's fail. Everyone who's shot a pump enough has short stroked it.
That only tells us you have seen people who don’t know how to work a pump shotgun. Everyone who has also shot a semi enough has seen it hiccup. Pumps best semis for reliability every day.
