I prefer revolvers for home defense. I have .38 spc and .357 mags.
I prefer a revolver over a semi-auto to avoid any risks of jams etc. I have a semi-auto and can clear jams and shoot simultaneously, yet still prefer my revolvers.
If you are concerned about over-penetration there is ammo available to reduce that risk.
My house is fairly small, with small rooms so I feel the area is just to 'tight' for a shotgun. I suppose if I lived in a house with huge rooms a shotgun might be a good choice. If so, I think I'd go with a 20 gauge. IMO, a 12 gauge is overkill etc.

I've never once seen my XD jam in thousands of rounds. What semi-auto do you have?
