Guys answering the door with a gun will back fire on you. Sort of. When I was 16 the girl I was d ateing told me about how her dad like to show his guns off to any guy that came over. Well I went prepaird. First time I met him I went to their house after I came out the woods when I went in their house he was sitting in his recliner cleaning his rifle. Had his chest poked out a little. When I came in I had my rifle in its case and my cleaning kit. I sat next him and broke my gun down and started cleaning it. He didn't really know how to react. But I did get his approval.
