My Local Pawn Shop has one of these. It looks brand new, it might be brand new. The idea of it is really cool. It is small, lightweight. A little thick, but really neat. I'm just not sure about it. Wanted to get your thoughts on it. He will sell it to me for $500.00. There is no follower in the mag. The rounds feed backwards. It's really something. Just not sure. What say you?
