Looking for some input. I have an FEG PKJ-9HP 9MM ( Think Browning Hi-power form factor). I bought this gun used. Had issues when I first bought it with the spent round partially extracted from barrel, but the next fresh round will jam against the partially extracted case. It would not jam after every shot, but at least after 3 shots. I have a friend with a properly functioning Browning Hi-power ( the parts interchange)and I was able to try his mags, barrel and recoil spring in my FEG. Still same result. I tried different brands of 9MM ammo. I throughly cleaned the gun, took the slide apart and cleaned some crude from the extractor spring area. I thought the crude was the cause. Gun still only partially extracted the spent casing. Since I figured i needed a new extractor and spring and was not sure exactly sure how to "fit" the extractor, I ended up taking the gun to a gunsmith, who replaced the extractor, extractor spring and put a "relief" cut in the end of the barrel. ( that pissed me off but he said he does this to all his 1911's). The gun functioned properly when I picked up the gun, I was able to fire 28 rounds without an issue. So I was feeling good at spending $75 for parts and labor. Cleaned gun and put into safe. Today was the first time I was able to take the gun to the range since I picked it up from gunsmith, about 2 months ago. After the third shot, gun is back to partially extracting spent rounds. I did not have a camera with me at the range, but i was able to almost recreate what was happening and take pictures at home. And now, inside the slide, I am noticing some scrape marks that i did not notice before. So, either the extractor and or spring still needs some attention, or maybe a weak recoil spring, now that the extractor is belived to be functioning properly?
