1939 P08 Ejector Keeps Failing

[mrerick]

Verify no binding in operation of the extractor, and that the well the spring fits into is clear and clean with slight lubrication.

Double check the surface of the extractor hook. I fit's rough consider a light polish.

Are there marks on the back of the frame where the toggle stops and strikes it? The frame ears look like they are slightly worn down. There might be inadequate recoil resistance. It's a finely balanced action.

The ejector has to push the base of the cartridge out from under the extractor hook very quickly. If the base was caught and stuck in the block well, it would try and compress the ejector instead of smoothly being pushed out. If the striking speed was fast, this could be snapping your ejector. Look at the hook profile and see how closely it matches the original hook.
