For those of you that are looking for options to help make your Gen 4 extract reliably, here is another option that works really well (at least for me).
Gen 4 G19
0-4-3 Recoil Spring Assembly
30274 ejector
15 degree, non-LCI extractor (OEM Glock)
Non-LCI spring loaded bearing w/ standard OEM plunger spring
I tested the above combination with 200 rds of WWB 124gr standard velocity ammo and the extraction was incredibly consistent (four feet to 4:00). 100% extraction to the same location; none of the random ejections that this Gen 4 was known for doing with the upgraded ejector and polished extractor. (BTW, the old school extractor came from my armorer's kit back when I first became certified in the 90s. I am glad I held onto the old stuff).
I got the idea to try this combo from reading Randy Lee's Apex extractor posts. Part of his theory is that the new, LCI extractor design introduced a few years ago by Glock had the potential to be less reliable than the extractor it replaced. When you look at the breech face from the muzzle end (with the barrel removed of course) you can see that the non-LCI extractor hook vertical portion is straight whereas the LCI version is angled on the lower portion. Randy's belief is that the older extractor design was more reliable because it had better rim contact during the entire extraction/ejection process. At least in my Gen 4, this seems to be the case.
Look at the area circled in red below and compare it to what your Gen 4 LCI extractor looks like from the same viewpoint.

Very interesting for sure. I will be keeping this set-up for the time being.
