konkapot Posted February 4, 2018 Share Posted February 4, 2018 Gray CZ Shadow 2. 2500 rds of reloads/factory ammo with 100% reliability. Black CZ Shadow 2. 500 rds of same ammo. 5 failures to extract. Two left empty cases in the chamber and 3 left the empty case partially extracted, but being pushed from underneath by the next live round in the top of the magazine. I am new new new to the platform. Suggestion? Link to comment Share on other sites More sharing options...
TrackCage Posted February 4, 2018 Share Posted February 4, 2018 Extractor tension. Have you tried comparing the two extractors for differences and/or replacing extractor spring Link to comment Share on other sites More sharing options...
konkapot Posted February 4, 2018 Author Share Posted February 4, 2018 I have done nothing yet; was really hoping that new gun(s) wouldn't already need new springs. The pin that holds the extractor in; is that a reusable pin? Link to comment Share on other sites More sharing options...
Gdub29E Posted February 5, 2018 Share Posted February 5, 2018 Sounds like a extractor issue. Could be a spring or a faulty new one. I would switch the uppers and confirm it does it on both frames. (Easy to do because you have both handy). Second you can take the slide off the one you know works and side a piece of brass under the extractor, then compare it to the slide that has the issue. If it’s brand new and your not comfortable you can sent it back to cz and they will fix it. Or you could have a competent gun smith look at it. Just and fyi, those pins are a pain to get out and I would not re-use them. Link to comment Share on other sites More sharing options...
konkapot Posted February 5, 2018 Author Share Posted February 5, 2018 Swapping slides is genius. Will try that today. Link to comment Share on other sites More sharing options...
NoKimberDave Posted February 9, 2018 Share Posted February 9, 2018 Could it be a rough/tight chamber? Just a thought. Link to comment Share on other sites More sharing options...
konkapot Posted February 14, 2018 Author Share Posted February 14, 2018 I polished the chamber lightly, ensured the gun was well oiled, and tightened the crimp on my ammo. This helped a lot but the issue still occurs with less frequency. Will play with it over time; the gray one runs 100% and will be a match gun. Will advise as I cipher through this.
