"Tuning" the 1911 extractor.
I was going to send it to a smith that really knows his stuff. It was going to cost me at least $100 and he probably would have done what I did to the extractor groove and sent it back to me. If you guys have never done this it is very easy. It takes more work & time to remove and put the extractor back together then grind and polish the groove. It allows the shell to align easier & faster in the extractor which makes the shell align perfectly with the chamber when the slide goes to battery.
Here is some reading to help:
Here is a drawing that I did. It isn't very good, but I hope you get the idea. (?)
Bottom picture is the jam.
Also the grind stone used in my Dremel. I was very careful not to touch the vertical sides of the groove while grinding.
PS: If you have questions please ask.
