Maybe you need a EGW extractor. And a extractor tension tool and checking device from Brownells use your trigger pull gauge to check the tension. Good luck. Nice looking build.So I polished the feed ramp on the 9mm barrel and was still experiencing feeding issues. Long story short, I don't think the feed ramp has anything to do with the problem at this point.
Even when a round is past the ramp and basically chambered and in the position shown in this pic, the round will bind in the chamber. In this pic, "something" is binding and keeping the round from chambering. The binding is enough to overcome the force exerted by the recoil spring and can hold the slide open in this position. I can get the round to fully chamber by pushing on the back of the slide but there is resistance and an audible "click" before the round will chamber.

I can fully chamber a round and pull back on the slide a little bit, maybe about 1/2" and it will hang up and have to snap past that resistance each time I do this.
I'm using an Aftec extractor, and what I discovered is that if I take the springs out of the extractor and reinstall it in the slide, and go through the same process as above, the rounds no longer bind up at a point most of the way to fully chambered.
So the problem seems to be "too much extractor tension", but that's the whole reason I use Aftec extractors. I've never had this issue before and my understanding is that using springs instead of relaying on the extractor itself flexing was done to eliminate this issue. I've never had to "adjust" an Aftec extractor.
Any suggestions are welcome.
