You aren't joking about how hard those PTPs can shoot, Allizard. At an OP last summer, a friend grabbed my M9 from me and got behind the enemy, shot a guy in the back. He was in a LOT of pain from those shots...
But, if a barrel made of plastic is the price I have to pay for such a great sidearm, I think I'll survive.
To keep people form trying to yell at me for letting someone do that, he wasn't close up when he shot the guy. A good 30-40 feet, actually.
