I'm all for responsible citizens owning guns, but the truth is for home protection all you really need is two things, a dog who will give you a heads up by barking when somebody is trying to enter the house who shouldn't be there and a 12 gauge shotgun loaded with magnum 00 buck if they do happen to enter. At night when it's dark and you're all disorientated, you want something that will give you a nice spread and a better chance to hit your target
