I don't think this song means any literal gun firing was taking place. I think this song symbolizes a complicated relationship between either good friends or lovers where each person took painful shots at the other and hurt one another very badly. A relationship that took everything out of each person till their was almost nothing left but scar tissue (It's a good thing I am made of scar tissue). With friends like that, who needs enemies?
