Well I finally got out and shot the Glock with the "new" ejector in it. The ejector seems to have fixed the ejection problem. I didn't get hit in the head or the face the entire time, and nothing went forward or left. I fired 100rds of WWB 115gr FMJ, 50 rds of American Eagle 115gr FMJ, 50 rds of American Eagle 124gr FMJ, 50rds of UMC Value Pack 115gr FMJ, 25rds of Winchester "Personal Protection" 147gr JHP, and 25 reloads of 4.3gr of Win 231, CCI Small pistol primer, Remington 115gr FMJ, OAL 1.100". So a total of 300 rds, maybe half a dozen of which sent the casing over my head, most of which seemed to be American Eagle 115gr. I have no idea why, but none of them hit me. Also with the 115gr American Eagle some (perhaps a dozen) seemed to eject more weakly than the other rounds, going maybe a foot out of the ejection port, but still to the rear right. Overall though I would say the problem is fixed. Though I can't account for why a few of the rounds were oddballs, it's definitely much much better than it was.
I also took the chronograph for the WWB haters. It was the hottest round out of all that were fired (avg 1140fps). Though the American Eagle 115gr was the most consistent (spread of 6fps, avg 1060fps), it was also the most "troublesome". The Winchester "Personal Protection" was the slowest and least consistent, which figures I guess because it was the heaviest round (avg 921fps, spread of 51fps).
The last 3 magazines I shot were mixed bags. One staggered WWB, PP, WWB, PP and so on, another that was basically the same but started on PP instead then WWB, PP, WWB, PP and so on. The other was leftovers of UMC, AE 115, and AE 124, staggered in that order, 1 of each type, all 3 types, 5 times for the 15 rds in the magazine.
The ejection was consistent enough that I was able to clean up brass by laying down a tarp to catch it. I posted some pictures, but there isn't really much to see from this trip. Now all I have to do is get my magazine back from Glock. That's why you only send in a bare minimum. I sent the pistol with the trijicons, which I would have removed if I had a sight puller, the case, the paperwork they needed, and 1 magazine. I got the pistol back in a different case with no magazine and they kept the paperwork they needed which is expected. That goes for any manufacturer, don't send anything extra.
