This thread popping backing up reminded me I was going to post a 20,000 round report, but there wasn't really anything to report. There were a few light primer strikes around the 8 or 9000 round mark that was due to some shitty Federal aluminum that had the same problem in multiple guns. Seems the primers were too deep. Other than that it's stoppage free. I haven't cleaned it and use Slip lube. For the last few thousand rounds I've used the Slip 30 weight. It seems to stick around a little better.
Eventually something will wear out and I'll post an update.
