FWIW...I have a buddy who paid for an open gun well over a year ago (I think it's close to two years)...he still has not received the gun. He contacted PT several times. Last I heard he asked for his money back.
I worked on another PT gun that had the whole corner of the feed ramp buzzed off. It left a gap between the frame and the feed ramp. The gun was a special order with the owner's name engraved, etc, etc. I was working on the gun because it would not feed .40sw ammo. I checked the chamber with a go/no-go gage and found the chamber was short. Additionally, when I ran my finish reamer into it the first time, I found the bottom of the chamber was not straight and parallel. The only thing I can figure on that was that a dull finish reamer was used.
