In relation to this thread here about locking your doors, say you were at home, doing what you do, and you heard someone obviously trying to get in to your home/apartment/yurt, whatever. I’m talking an obvious stranger at an odd time. What do you have in your home to defend yourself?
I, personally, believe in the pump shotgun. Not only is aim not much of an issue with a pump loaded with birdshot, but it’s not going to over penetrate walls in the case of actually having to fire. However better even than that, there isn’t a person alive in the world who mistakes the racking sound of chambering a shell for anything else. It’s a universal sign for “Stop what you are doing, now”.
