Home defense? Double barrel 12 ga shotgun with short barrels. No technology to overcome fumbling around in the dark except a safety and a spread that will ruin whatever is in front of the gun. I don't care what you load in it, but 00 buck in a 3 in mag makes a hell of a hole and a lot of racket. Inside of a house, the guy on the receiving end is gonna be either deaf and covered in his own urine or real f'd-up.

Please boys, don't saw that sucker off too short, Mr BATF no likee and it just ain't worth it.
