I bought an Ed Brown extractor in .40/10mm for my 10mm experiment. It looks similar to the 45 extractor but relieved up front so the hook reaches closer to centerline. I think I could've done the same with a .45 extractor... maybe...WalterGC said:Jeff,
This might relate to your 10mm conversion. I'm currently playing around with a comp'd KKM 10mm G21 conversion barrel. Since the G20 (10mm) extractor won't work, I'm trying to modify the two versions of the G21 .45ACP extractor to work with the 10mm cases. Still not getting 100% extraction. Might be an easier conversion in a 1911.
