Slide Rail Dings
No, the roll pin on the right side of the frame just appears to be to long, it's flush with the outside of the frame rail and protude into the path of the internal rails that strips a round out of the mag. If knocked back out of the way of the internal slide rail it would protude into the path of the frame and slide rail, which would cause additional problems and slow down the movement of the slide while ejecting and feeding another round in the chamber.
I think I'll just polish the the ding and trim a little off the rolled pin #9 and fire a couple hundred more rounds and see what happens then. I think those guys that polished the rails that were dinged must have polished enough off that it didn't contact that #9 pin and solved their problem. I'll soon find out and will post a range report. I've got my fingers cross that I don't screw up a nice firearm.
