I have only 200 rounds through my new full sized USP 45. When I first brought the gun home and field stripped it, I noticed that the black finish on the forward end of the recoil spring/rod appeared to be very worn. I called the dealer to ask if the gun was indeed "brand new". He assured me that it was brand new. Anyway, I just got around to taking a photo of the end of the rod today. What you see in the photo is EXACTLY as it appeared when the gun was brand new. Firing the 200 rounds has not increased the level of "wear" at all. The surface of the slide that mates to the end of the rod looks pristine, with no marking or discoloration at all. The areas of the rod end that appear white in the photo are actually bare metal. Anyone else ever seen one like this??
