I dont know anything about shotguns but I did inherit these two so now im very interested in learing about them. First they are both 28" barrels so, Im thinking for HD I need to swap the barrel and get an 18" for one of them (remington b/c I couldnt find anything on line for 18" 835 barrels)..Im just wanting some info on these guns. Also since I dont know much about shotguns and dont even know what questions to ask..is there a website w/the abc's of pump shotguns ??? thanks for any and all info.
