So, I've got my rifle all cleaned, lubed, and re-assembled. I literally inspected each part under a magnifying glass. Even though I couldn't see any difference between them I swapped out the ejector just in case. I'll get out and shoot it probably Tuesday or Wednesday to see how it performs this time. If I'm still having stovepipe issues I'll order an Mcarbo extractor but that's about the limit I'm willing to spend. I don't mind shelling out money to fix something but I hate buying medicine for a dead horse. I made that mistake a few times as a kid but I learned my lesson. So, fingers crossed let's see what happens. The sad thing is that if it does end up being a failure there's nothing out there right now that I'd want to replace it with. Maybe a 77/357 but I've looked at them on GB and I'm not crazy enough to pay the kind of money they're asking right now.
Suggest being patient, and trying to not become frustrated. I think most of us understand your frustration, and have BTDT at some point.
Suggest replacing extractor
might be useful, but so might be replacing extractor SPRING as well. Good on you for making minute exam of the rifle, but springs are hard to find fault with, excepting having a known good spring for comparison.
No Expert on your PCC, but how does the ctg
ejector look? Instruction manual and exploded parts diagram:

Also suggest buying a second mag from trusted source.and trying it out. Blowback type firearms inject a lot of crud back into the action and magazine; both rifle and magazine require periodic cleaning and lubing. Suggest dismantling magazine, cleaning it, giving the spring a very light film of oil, and re-assembling.
It will all come out right, even if you need to send it back to Ruger for repair.
