Failure to extract is about the worst kind of jam you can have. It really takes you out of the action! Some causes that usually require factory repair: poor barrel-to-slide fit; poor barrel timing due to bad barrel or locking block specs; of course, restricted/defective bad extractor or extractor spring; rough or out-of-spec chamber; etc.

I didn't see any obvious rim damage to the fired case from the extractor claw so I guess sticking in a rough chamber could be eliminated...

All these kinds of problems usually require a factory warranty repair. Put your original parts back in and send it in. Good Luck.
