Has anyone here had a 5in 1911 throw a spent case it was extracting back into the feed lips of the empty magazine on the last round? The case jams up at a 45 degree angle and and slips off the extractor and the slide is locked back. I use metalforms with heavy springs and this only happens every once in a while. Was told that the extractor was too tight and/or it was clocking and letting the case slip down off the breach face. Which make sence but just wanted to bump heads with others before buying a new firing pin stop and/or extractor.
Your extractor is clocking... or rotating... and dropping the last round. The reason that it happens on the last round is because there's not a round under it to keep it from falling off. If the round is actually being stuffed part- way back into the magazine, the tension is good. If you have failures to extract or weak ejection on other rounds, crankin' up the tension might help... but too much tension will result in failures to feed/return to battery.
Extractor clocking? That is a real possibility.
Extractor too tight? I doubt it, more likely it has insufficient case tension.
Another possibility is that the face of the extractor is contacting the bevel on the cases extractor groove.
Ok, thanks 1911Tuner, thats what I thought it would be. I'll try to fit a new firing pin stop and see what happens. Failing that thou, a quality extractor is in order too I guess. Any tips?
Brown Hardcore or Wilson Bulletproof are both good, and I've had excellent results with both. Of the two, Brown gets my nod, but I may be switching to a newcomer in the extractor market very soon.
The Wilson needs a bit of prep on the hook end, but has extra material in the slot, so fitting a firing pin stop may not be needed. The Brown requires less hook prep, but doesn't have the shallower slot... and is overlength on the butt to allow for blending to the slide. The dimensions on some slides don't require it, but most do.
Cylinder & Slide makes a spring-tempered extractor from the specified material, but their hooks are usually too deep and require modification... which voids the warranty. I don't have a problem voiding the warranty, but you may not want to.
Caspian also makes a very good extractor, but I've never used one of theirs... so I can't comment on any of the pros vs cons. Likewise for the Nowlin Tuff Stuff extractor.
