I have a few hundred rounds through my G17 9mm Gen 2 sub 2000. After cleaning it yesterday I noticed what appears to be damage to the barrel locknut and washer (I think that's what they are):
The indents match nicely to the bolt face, so it seems like the bolt slamming into the nut/washer is damaging them.
I've had zero failures and the gun performs really well, but I'm obviously concerned that I'll cause permanent damage with continues use. Doesn't look like "normal wear to me, and the last time I cleaned it I don't remember the marks being there.
Am I now one of the "send it to Kel Tec" guys, or is there a simple reason?
Thanks!!
