I bought my 2018 Czech made P-10C a month ago. In the course of shooting about 400 rounds of FMJ ammo, the pistol would only pull an empty case half way out, causing the live round to jam underneath it. The FTE's were very numerous. I sent it back to Kansas City and received it 2 weeks later. They polished the front of the extractor and adjusted it, and also polished the feed ramp. I shot 100 rounds through it, and it runs great. I'm very pleased with CZ's repair process. I never would have thought that polishing the front of the extractor would help. Looking forward to running a lot more rounds through it!
