Fenrisulfur

I switched to 11 lbs recoil spring and +500 rounds later I have not experienced it again.

I just replaced the extractor and spring, only 200ish rounds. So I don't know. No, made by Zendl. https://seboweapons.com/en/cz-spare-parts/172-large-safety-both-sides-type-2.html Very comfortable and wide, but probably not legal for IPSC

Hi All I have a S2 that so far has about 2-3K rounds through it and I have experienced twice now that a fired round fails to be ejected out and a new round jams up underneath it causing a failure. Both times happened during a lvl 2 match of course and cost me a lot of time. I have a 10 lbs recoil spring and a 8 lbs hammer spring with a Ultimate trigger and a reduced firing pin spring. Everything else is stock. Since this has happened I have replaced the extractor and extractor spring and cleaned it (there was not much gunk under the extractor). I'm thinking it could be one of the following: 1) Drag on slide. (I have another S2 that has thousands of rounds through it and I have never had that issue, but it doesn't take much drag) 2) Low powder charge round. Could have had enough powder to clear the barrel, but not to eject. (It did not feel like low power charge and the hit was fine in both instances) 3) ?? I have a big lvl 3 match coming up and It's frustrating that I have not identified the issue causing this. Any suggestions would be appreciated. Brgs.
