Ok, so we had a few slow moments at work today and one of my co-workers was flipping through the blue book of gun values. I would not have believed it if I hadn't seen it with my own eyes, but there was a 50 BMG handgun listed in there. 13" barrel. Has anyone ever heard of this thing? Or seen one for themselves?! We came to the conclusion that shooting such a handgun would have to shatter some bones in the arm. I'm just curious if there is such a thing anywhere other than listed in the blue book.
