"Not for use in the Glock 26" from:
https://www.apextactical.com/glock-failure-resistant-extractor-gen-5#glock_fit=gen-3-5
Apex Tactical doesn't recommend, and outright says not to use its extractor in a G26 (gen3 in this case).
For my G26gen3, the #336 ejector worked fine and the #30274 and #47021 ejectors didn't change this gun's ejection. I did have some casings eject to the left instead of the right, btw. I just didn't want casings ejecting directly into my head as my G17gen3 used to do. In the G17gen3 I had, the #30274 ejector did work, but the Apex Tac extractor did not work well (with or without substituting the EDP spring and non-LCI spring loaded bearing).
For my G17gen3, the ApexTac extractor intermittently caused the spent casing to be pulled above the ejector, yet stilled held by the extractor, which then caused a horizontal stovepipe situation (impossible to clear by merely swiping one's hand across the top of the slide as the stovepipe is all but flush with the top of the slide and there's now a double-feed situation). But this is all just old personal info and not particularly related to a G26gen3.
I'm actually carrying my G26gen3 today and it's worked fine with the stock 336 ejector, but I did try it for awhile with the 30274 ejector as I mentioned. Just be patient and the 9mm Gen4 trigger mechanism housing with ejector will eventually be back in stock somewhere.
