I recently meet 2 wonderful people who created a question in my mind.
I have a SA 1911 45 ACP and when a round loads into the chamber the extractor engages the brass. I have disassembled the pistol and have noticed that the extractor holds the case firmly against the face of the bolt (I'm guessing it is called a bolt). Because each piece of brass is not exactly the same length, I'm guessing that with every round, the mouth is not pressed against step inside of the chamber (please help with the correct terms) but is being held against the bolt face.
Questions:
1) Does the extractor engage as a round is being sheared from a magazine?
2) Does my extractor need to be adjusted?
Having asked all of this, I am wondering what will happen to the cycle operation if I put just a little too much taper crimp on a round. I am looking to get the proper tension but I need to understand the bigger picture.
Thanks in advance for your help.
