good luck, my bud had the remington pump with I think magpul fore end, neither of us could hold on to the forearm with 23/4 buckshot, put a strap on forearm, broke it in 3 shots, I got the remington semi auto, was fine and fun but tried to put a flashlight on it, hit my thumb with the streamlight switch, cant remember who made it but it has to come back a way for you to reach flashlight switch, after firing twice that was enough with the flashlight, had a lot of fun blowing up beer cans, coke cans water bottles,., but sold the gun as its impractical, I guess it would be a good truck gun for daytime, no easy way I could see to put a usable light on it I can see. If its anywhere near your hand its gonna hurt. Would not touch the pump model of any variety.
