Actually I have a suggestion, the bipod be remounted off of the pump somehow so you can still run the action.
Also yes I am that shaky sometimes I need a gun rest especially when bracing for slug recoil with a 7 lb gun. Hell I even use a shooting stick with my Crossbow, and shoot benchrest on sandbags with a Ruger 10/22 even at 50 yards, considering that a 12-gauge slug gun weighs much more than either of those other 2 guns, its not a terrible idea. Now I'm not saying its absolutely needed, but every little bit helps.
As I stated before: Bipod+Rifled Slug Barrel=Potential, theres just too much other crap on that gun to make the point relevant.
