I prefer the Smith & Wesson model 500.

It is WAY more powerful than a 44 mag. This would come in handy if the bad guys coming into your house are wearing body armor. It would also come in handy if you flee the bad guys in your car. If they follow you, you can fire some rounds right through their engine block to disable their vehicle.
