I think I'm going to pick up a home defense shotgun in the next couple months. I'd like to get your input on a solid pump gun, and I'm thinking about the 870 "Regular" and Tactical, the 590a1, and the Nova Tactical. I know I'll need practice with it, since I've owned several pumps before (Winchester 12s, Ithaca 37s, etc.) but honestly was never the best with them when bird shooting. I tended to do better with O/Us (Beretta and Browning) and autoloaders (Montefeltro, Auto 5, AL391). That said, there are a few home defense autoloaders available used for under $1k (VersaMax and Benelli M2) that could fit the bill as well; I just know know how reliable they are in high adrenaline situations where they may not be shouldered properly. Any insight is welcome! Thanks.
