Get yourself a Remington 870 with a mag extension for Home Defense! Reliability would be my main priority and a pump shotgun gets my vote:thumbup: Semi-auto shotguns are fast, fun, and has less recoil. But I still prefer a foolproof setup if my life is on the line.
:thumbup::thumbup:
870 deer gun (20" IC smooth bore, rifle sights) and about another hundred bucks for two round extension, new follower, fire sights and you're good to go.
