I do not answer my door unless I'm expecting someone. That said, a few months back there was heavy knocking at my front door that wouldn't stop. I finally got pissed, grabbed my XDM 45, and jerked open the front door. It was a police officer. It was quickly determined that he was at the wrong address. Before he left he said " can I ask you a question?", to which I responded sure. He asked "do you always answer your door with a gun in your hand?" I said "yes, don't you?" He thought for a second, smiled, and said "I guess I do". We both laughed and he went on his way.
