Thank you for the help! There's a fellow selling new old stock extractors. I've wanted one as a back-up regardless, but feel that I may need one because when I pull the slide back to do a press check, the round dips down instead of being firmly in place like on most of my other pistols. I can't think of anything else to be causing the issue. I'll probably take the gun and extractor to a gunsmith to have it fitted as well as detail cleaned and will definitely report back!
While I'm thinking about it, though, would anyone have any leads on new barrels or any other parts I should look for to keep the gun running?
