I have a PCR that I have fired about 2,000 rounds. Don't plan to do soon, but at some point considering detail stripping slide to remove any crud. In my experience crud collects in slides esp around the extractor. So I was wondering if anyone has detail stripped their PCR slide or that of similar CZ pistol? Also did you find much crud? Where was crud, around extractor, firing pin, etc? I was thinking perhaps only necessary to remove extractor, as that is where most crud would collect. Also did you reuse roll pins or replace? How hard was it to do? Any tips, instructions? Thanks for any info.
