I've allways said that if you really want some "home" pretection...try a 12ga pistal grip shotgun. The mossberg 500 special purpose persuader, is my gun of choice..(7+1) capacity..got the 18 1/2 barrel. Some call it the "cruiser" pump shotgun; It's loaded with 3' 4-shot turkey loads, at this time!
Just a great gun if you get in a shoot out..close range, in the dark...in the house. Just my oppinion.
