Have a fairly heavily modified limited pistol I've been trying to diagnose the issues with. About every 50ish rounds I'm having a stove pipe like what's show in the picture. The frame, slide, and barrel probably have 50k+ on them so I don't know if this is just failing because it is getting worn out. Seems like the extractor claw occasionally is slipping off leaving a spent casing in chamber as well while trying to load another round.
It's a G34 barrel in a G35 slide. It's not a conversion barrel and has only begun to act up in the last two thousand rounds. Prior to that it has run factory and reloads very well. The slide was further lightened and I've continued to run a 13lb recoil assembly. Not sure if increasing spring weight would help.
I've replaced entire extractor assembly. Tried 9mm and 40 extractor. I've honed the chamber with a reamer, it didn't remove any material. I have not messed with spring weight, I have not replaced ejector with a 9mm ejector.
Any ideas what's going on here?
