I've got a Mark II 22/45 that's got approximately 15K rounds. It started developing extraction issues. It would also fail to lock the last round open. At the time I had Winchester Wildcats so I was attributing some of the issues to poor ammo. Then it started doing it more frequently, to the point it couldn't go through a magazine without an FTE.
Naturally I replaced the extractor with one from Tandemkross. I also replaced the bolt stop with a factory Ruger. The old bolt stop lever did look worn out when comparing to the new one. Same with the extractor.
Today is the first time I got to test the pistol with the new parts; I'm getting positive extractions but now I'm not sure what's going on. It's somewhat of a stovepipe, where the extracted case and the fresh round is meeting somewhere in the breech. It does have failures much less frequently though, probably every other magazine with Federal. This occurs with both factory Ruger mags.
The feed ramp doesn't feel like it has any burrs or imperfections.
My next thoughts are recoil spring and mag springs? I did a good field strip and cleaning of the gun and magazines before the range today. I've read about 22/45's with many more rounds on the original recoil spring with no issues.
Thanks!
