I'm in the process of fitting the EGW extended ejector in my Caspian build. I have to admit that ejector tuning is the most bewildering part of 1911 work for me. Everything else with the 1911 seems like straight forward science, but the ejector seems like voodoo.
First of all, the EGW ejector is oversized in almost every dimension and required extensive fitting to the slide. At least it dropped right into the frame holes, though.
After fitting it to the slide, I cut the nose back enough to ensure that it would eject a live round without getting caught up. I also ensured that the top round in the magazine would not hit the bottom of the ejector at any point during feeding.
Now onto the voodoo.
I've seen every variation of ejector nose shaping I can imagine - angling it backward and forward and even compound angles. I've also seen it beveled on the inside edge, the top inside corner, and toward the ejection port. I've also seen the top of it rounded off.
My question is what is a good starting point? How should I shape it before test firing? I'm suspicious that ejector tuning is one of those counter-intuitive things, and what I would do to influence ejection in one way would actually produce the opposite result.
Is hand cycling with empty brass a good indicator of ejection patterns when live firing, or does it not help at all?
Help please and thanks.
