Unless you have a reverse pump, then you pull /push. Extremely rare, have only seen a couple in my years.
I believe that he's asking about the "pull to the rear with the control hand and push forward with the support hand upon firing", creating a bit of a shock absorber effect. This method was first (AFAIK) popularized by Rob Haught, and allows even smaller statured shooters to shoot without undue abuse. I use it myself and don't even contact my shoulder with the butt of the gun (although I am far from "smaller statured")...
There are indeed "reverse" pump actions.
The RMB-93 and variants being the most notable.
I'm aware of that, I just don't believe that is what he's asking about...
Sometimes when I have been shooting my doubles for a while I switch to one of my pumps and I pull the trigger a second time without sliding the pump and have that moment where you watch the clay or bird fly out of range.
I can't believe this is a real question... IF you have to ask this, you should NEVER own a pump shotgun...
