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!!

Here are two Sub2000s with about 8K (top) and 10K (bottom) on them.
Thanks MarkCO.

Looks like mine has a LOT more evidence of impact after a few hundred rounds than yours do after several thousand.

I sent a mail to Kel Tec asked for their guidance.

Maybe they made mine too "tight" to start? The gun shoots very high in general, so maybe a problem with the initial setup?

I agree your looks worse. On both of the ones in the photo, at 12 and 3, at the ends of the shiney spot of the quarter circle, there is a very slight ridge I can feel with my finger, maybe the thickness of a piece of paper.

In yours, about 7, it looks like there might be a burr or ridge on the corresponding point in the bolt.

I don't know enough to tell you why yours is different, or if it is wrong, but in the 6 I have, I don't see any as bad as yours.

That's the back end of the steel sleeve that the barrel threads into. The locknut and washer are forward and under the forearm. That does look like more ding than normal. See what Kel-tec has to say. If it was mine i'd use a fine file to just knock down the sharpest spots and see if it settles down over time. But I do understand your concern. Let us know what K-T has to say.

Thanks 3wbdriver. I'm kind of hoping that KelTec says to just file it down!

That was actually my first reaction, but I stopped myself "just in case".

Care to share what they said?
I would have said normal wear looking at the pics on my phone...
Mine show wear, but have more rounds.
I will check mine when I get home.
Wasn't too much discussion really. I opened a ticket and shared the pictures with them. Also, the gun fires VERY low (front sight screwed down as low as it can go just to stay near center) so they asked me to send it in.

If I had a few thousand rounds through it I might agree with normal wear, but I bought the gun brand new a few months ago, so I only have a few hundred through it at most.

I'm not familiar with the Sub line, but if that peening is on the upper half of barrel when in firing configuration, it may also be causing the gun to shoot low.
Yes, my concern was that the two were related, so I decided that sending it back to the factory for a look was the best idea.

The sub 2000 is absolutely my favorite gun to bring to the range, so I'd rather take the time now and send it in rather than have something significant happen because I waited.

If I get too impatient I may have to puck up another one while I wait!

Quick update.

I received the gun back from Kel Tec last week (while I was on a business trip), so they beat their 8 - 12 week estimate by a very good margin.

The the impacts from the bolt are towards the "normal use" side. They did notice a burr which was filed/addressed and they made adjustments to the front sight (I had told them about my issues with the gun shooting VERY low).

I haven't taken it to the range yet but they test fired it so everything should be OK.

Overall I'm pleased with the experience. My gun got a once-over and tweaked by the tech and I now have peace of mind that there's nothing flawed.

I'll let you know how it does at the range later this week.
