Aftermarket Glock 19 slide - tight extractor

I have an issue with a tight extractor on an aftermarket Glock 19 slide that I got as part of a kit from 80PercentGlock. The extractor is so tight that it is very difficult for the case rim to slide in and out of the extractor which causes occasional failures to go into battery and difficult extraction as the round has to literally be torn out from the extractors grasp by the ejector. I swapped parts back and forth with my G23 and I've definitely narrowed it down to either the extractor or possibly the slide face was milled a few thousandths too tall under the extractor. Either way, cases don't want to go in and out.

I'm considering the following options:

* Replace with a Glock 23 extractor. The 9mm ammo seems to cycle fine by hand in my G23 slide. This might be the easiest route but don't want to risk an extractor that will occasionally not grab a rim. On the other hand, a .40 extractor with the offset 9mm ejector may not be an issue.

* Sand down the extractor to open it up a little and make it as smooth as possible. I've done this before on other guns and it's a very slippery slope and very easy to ruin an extractor. I also don't know if the OEM Glock extractors have a surface hardening/Tenifer treatment that would be removed by sanding them down.

* Replace with an aftermarket Glock 19 extractor. Problem is that I don't know if it's the extractor itself that's the problem or if the slide is a little out of spec - either is possible. I already had issues with the barrel that was part of the kit being out of spec though.

Any suggestions? I'm really leaning towards just ordering an OEM Gen 3 G23 extractor as being the easiest option.

Call or email the company. I got a 17 complete slide from them that was just no good. FTF, FTE stovepipes, etc. I swapped it with a factory G34 upper and it worked flawlessly, so it was not the lower.
I emailed them and told them all the trouble shooting steps I performed and they replaced it. They should make good on it.

Fixed it, it's as smooth as silk now.

80PercentGlock sent the wrong extractor spring bearing (plastic buffer at end cap) with the kit. The spring bearing was for a model without LCI but the included extractor is LCI. This spring bearing was a little longer and full profile vs tapered so it stopped the LCI extractor from opening all the way to accept the case rim. The easy fix was to just trim the plastic "bearing" (I hate that name - it is in no way a bearing) to remove the "tail" to allow full extractor travel.

I discovered this after beveling and smoothing out the extractor, which helped a little before I noticed that the extractor just didn't have enough travel. Extraction seems to be good by hand cycling but I'll need to take it to the range again to be sure. The smoothing and profiling seems to have changed the ejection angle a little for the better - more forward and to the right instead of up and back but again I won't know until I actually put a few hundred rounds through it.

I'll probably reach out to 80PercentGlock and just see if they can send me another spring bearing and maybe an extractor just to be on the safe side. Not having the tail on the bearing to act as a bump stop may or may not cause issues under recoil but the end cap is still there so spring preload is the same.

This is after having to sort the barrel out which had a rough, narrow, poorly profiled feed ramp and with a sharp edge at the chamber. I can crank out these frames in about an hour with basic hand tools but these aftermarket slide parts kits need a lot of work.

I didn't have anything like those problems with my Brownells slide... rubbed the rails a touch at a couple points, but that was it. Once I gave it some wheel grease as lube, it ran fine (until I put a comp on it, but that's a different saga). I am really suspicious of these all-in-one kits... seems like cost cutting is a big thing with them.
