I bought a PT 145 Mil. Pro about 6 months ago. I have had no jams or feed problems and the gun has performed flawlessly through 500 plus rounds. One thing that bothers me is that the primer indents have what looks like a "drag" mark for lack of a better term. My local gunsmith looked at it and said to keep shooting it. Like I say gun has been flawless so far but I am wondering if anyone else has had this problem and should I be concerned?
