Which pump shotgun do you prefer as a “boat gun”, the Remington 870 Marine Magnum, the Winchester 1300 Stainless Marine, or the Mossberg 500 Mariner?
I think they are all good guns for boat defence. I bought a Mossberg 500 Mariner, the model with the standard length magazine, specifically because it accepts regular Mossberg 500 barrels. When I ordered my gun I also ordered an extra 28″ ventilated rib barrel. This allows me to use it as a conventional shotgun for hunting or informal clay target shooting. I also bought a Pachmayer pistol grip for my Mossberg, as it substantially reduces the felt recoil compared to the pistol grip supplied by Mossberg. I chose the Mossberg based on good reports I have heard from other boat owners, and because it seemed like a good deal. I once sold all three brands at the retail level, and found all three to be very reliable.
