This of course plays into the fear US gun advocates have of any attempt to remove their gun rights. If it were to happen though, then maybe as a prepper type with a house and lands in the woods you'd stand a chance against an armed mob that came for you, but certainly not the government. If you're defending your sub-urban house (or even worse flat), I suspect that the gun you have for self defense would make very little difference to the final outcome, but might make you feel a bit better about it.
