Thanks for posting this Tony, it jogged a few thoughts. Will be very interested to hear your results. I have the exact opposite issue with the extractor (PM9 however): it always protrudes, even when empty. I am having feed issues as well, which I'm trying to sort out in another thread, with focus on ammunition, magazine, and shooter for the moment. I've been meaning to get around to thinking about how that screwy extractor could play a role. Out on loan right now to see if an experienced shooter can get failures with assortment of ammo, but when I get it back, I will now load some cases as you did to see how it sits. Thanks for the post.
