I disagree. Unless you have a house with shooting lanes of 15 yards+, you're going to have to be just as good of a shot with a shotgun to hit much as you are with a pistol.
As soon as its broken in, this is going to be my go to home defense weapon:
(not my pic)
I'd rather have 33 hollowpoint 9mm on tap with another 33 in a reload than 7 or 8 shotgun shells for HD.
