Sorta' on topic, but not being a firearms or ballistics expert, I heard that a shotgun with #4 shot is the near perfect home defense weapon because, 1. you don't need perfect aim; 2. #4 shot does a good job on burglars; and 3. it won't penetrate walls, so you have very limited damage and don't injure innocent bystanders in the next room, etc. However, in case the shotgun doesn't completely finish the job, every nightstand should contain a revolver or Glock or something to put one or two bullets in the head to make sure that the intruder doesn't get up and cause you harm before the deputies arrive.
