I’ve always been perplexed with tuning or adjusting the extractor tension for a 1911. I can never get my head around what would be considered a properly tuned extractor even after reading what most would call, the bible on proper extractor tuning by John Marshall of Wilson Combat (http://www.m1911.org/technic2.htm)
I understand why and how you’d tune it but will never understand what would happen to the case if tension is too tight, or if the face of an extractor is not beveled.
This excellent video by doctruptwn on YouTube is a great walkthrough on how you should tune and test your extractor tension. It put me on the right path to understand this more.
After watching that video and reading the article again, I managed to successfully adjust the extractor on my Kimber Eclipse Pro II and now it’s ejecting rounds 3 ft away from me instead of getting it shot at my forehead.
