I don't shoot my Combat Master a lot, maybe 500 rounds a year, and I've gotten accustomed to its being a bit finicky; it seems that when the springs are fresh, and it's clean and lubed, it runs great. I rarely shoot more than fifty rounds before stripping it, and detail cleaning. The other night, I shot a 70+ round "tactical" match with it, and had two stovepipes. I started fretting about this or that, and then I rememberd the last stovepipe I'd had, two in fact, on a Government Model that shortly lost its extractor hook. I started cogitating, and thought, maybe the stovepipes are related to extractor tension? I'm thinking the extractor in the GM was cracked, or otherwise losing its grip immediately before the hook came off. So, I pulled the extractor from the Combat Master, and put "a little" more tension on it. I was afraid that it was too much, based on how relatively difficult it was to push the extractor back into place, but I've since gone 100 rounds without a hitch. From day one, stovepipes have been the only real bugaboo with the gun, so maybe now I can settle down and just enjoy it.
