I attached a hand drawing of the change I made if you want to give it a try with your adjusted EDP. I have also wanted to do another experiment if I ever get a customer to come into my shop with a 9mm that has the “bad ejection” problem and that is to see if the poor ejection stays the same when the ejector is removed from the trigger housing. My thinking is that on some of these pistols for whatever reason the next round in the magazine is causing the empty to be ejected before it even gets to the face of the ejector and that is what is causing the problem.
I think you are on to something. I have a gen 3 19 that has erratic ejection. The 30274 ejector helped, but ejection is still really weak.
I had my gen 2.5 26 at the range last friday. With the 10 round 26 mags, ejection was perfect with all brass landing in a nice little pile. The 26 mags had #1 and 4 followers. I tried some newer 15 round 19 mags in it and it started displaying erratic ejection. I fired several mags through it and on each, the last round ejected at 12 o'clock a few feet in front of the gun. It seemed to me that it is possible that the follower started the ejection process before the case hit the ejector and when the slide started to move forward, the breechface hit the case sending it in the 12 o'clock direction. The 19 mags have the newest #6 gen 4 followers. When inserted into the frame of the 26, the #6 followers sit much higher in relation to the feedramp than the #1 and 4 followers. It is interesting that erratic ejection followed the 19 mag.
Also, when I detail stripped the 19, I noticed the walls of the extractor depressor plunger was chewed up. There were alot of debris in the channel for a gun that has only 500 rounds on it. I wonder if this has anything to do with the reason some folks don't start having problems until they hit a higher round count? If the extractor depressor channel were cut too small or the body of the plunger was slighly too large, what effect would the increased friction on the depressor plunger have on extraction and ejection? Would it affect slide velocity? Would it prevent the extractor from rotating freely?
