Not sure I'd be using .410 shells for home defensive. Ammo is expensive and underpowered for humans (in general). I guess it could work with .45 Long Colt, but .45ACP works just as well. Home defensive shotguns usually aren't worth the money if that's the kind of gun you want, any 18" or shorter barrel will work, and honestly, who needs 7 shells in a 12 gauge for the house? Maybe if you wanted to turn a person into some sort of minced meat.
