Hi Folks,
I recently bought a used Colt MKIV S70 1911a1 (.45acp). It's in very nice shape, but it's not functioning reliably using 230gr fmj factory ammo.
I believe the failures are related to the extractor. Originally the extractor was too loose. Now, it seems a bit too tight (I adjusted it after my first range session). I have some questions regarding the extractor:
1. How much tension should be in the extractor?
2. I'm thinking of replacing the existing extractor with an Ed Brown extractor. I've read that the extractor should have the lower edge and lower corner of the hook smooth, to improve reliability and to avoid breakage. What's the best way to do this? Do I stick the extractor in a vise and file it or stone it or use some kind of emory paper?
3. Can you recommend some good online references or other references for tuning a 1911 extractor?
Thanks,
IrvJr
