One thing that you have to remember with handguns like the .357 or the .44 mag is that they can penetrate an intruder and still have enough juice to go into the next room. Also If you miss with one you can put it into the neighbours house. Be sure to use the home defense fragmentation ammo that won't go through drywall.
