My extractor was really tearing up my brass. The factory extractor had some sharp edges that dug into the case noticebly. Since I reload I would like to keep them in good shape. I tried to change it out with some other series 80 extractors that I had on hand from Ed Brown and EGW. The problem is that neither of those will hold the plunger in correctly. It will fall out everytime I go to reassemble the slide to the frame. The factory extractor holds the plunger fine. Should I try a different plunger? Where can I find one? This is a new problem for me and I would like to be able to fit any 80 series extractor into my PT1911.
