Every criminal knows what the business end of a shotgun means, there is no question or language barrier. Rifles and pistols offer some chance of survival for the thug because it's easy to miss, with a shotgun with shot shells #4, #5, #2, 00 etc... anyone downrange is dead. I like the #4 hevi-shot best as it's good for turkey. raccoons, skunks, woodchucks, and coyotes as well as the invaders. 00 buck shot and slugs have a hell of a kick but they kill fast. #4 shot might not drop a human dead instantly but I guarantee he will stop what he's doing immediately. Chance of survival after getting blasted at close range with #4 shot is probably 5%, my guess. If you don't have kids just keep it loaded with an empty chamber next to your bed, if something happens you pump a shell in and that should be enough to get the intruder to voluntarily surrender. I don't have a light mounted to mine but duct tape works so does simply holding a maglight against the pump part of the stock.
