Stovepipe, FTE, troubleshoot

[Koda]

A likely story. I note you did not post the video so we could revel in all the limp wristing glory

But good that you got it sorted. I am mildly surprised that the extractor was behaving that way even though it seemed to hold the cartridge decently well on the static testing, but a worn out edge or funky geometry could easily explain it. And the optic being a contributing factor makes sense too.

I will have to youse your success as motivation to sort out some known issues in a few of my guns. I think I know what a few of the problems are, but I actually have to go and test it to be sure. We will see what happens after the holidays.

So the original extractor wasnt a Glock OEM one, it came with the Alpha SS slide as a complete slide. What Ive learned is not all aftermarket parts are equal. I do not think the optic (or WML) has any influence on things.
Come target shoot with me someday so we can poke fun of both our limpwristing... . lol

Many, including myself would not use aftermarket Glock "small parts".
Glock OEM small parts are so reliable and so inexpensive it just rules out aftermarket.

Adding an optic can mess with slide velocity in some cases and RSA adjustments may be needed.
Some Glock 22/23 Gen 3/4 have a history of not functioning with certain WML's.

Yeah, at first I didn't want to use Glock parts just for the sake of building my own but gave up on this, there's just too many aftermarket parts out there all with their own varying quality and tolerances. I got to the point I just want the darn gun to run.

I can see how adding weight to a slide can affect operation but it doesn't make sense to me that side weight changes cant be solved with simple recoil spring changes. The problem for me in this case is I already addressed that (I have a Wolff spring kit) and when its a different component thats the culprit it gets confusing when all the advice given is about the optic or something else as the problem. What I don't believe is that optic weight cant be easily resolved, as its own problem.
Somewhere along the way the extractor wore out. Ive had it run fine for several hundred rounds with the optic until the extractor wore, the gun ran fine with all the different recoil spring weights. Previously to the extractor issue I had feed issues that also took a long while to resolve that turned out to be the Alpha SS barrel, so this pistol has been a difficult build from its beginning and all because of aftermarket brand components. I have two Alpha SS complete slide assemblies now and both guns had to replace the barrel to feed right, and both now have Alpha slide components break or need replacing. The slides itself seem to be fine.

Not to pick the nits, but to be able to remedy the problem, one needs to know exact symptoms.

I've not read all the posts, so going off the OPs post only.

First, that's neither a stovepipe or a fail to extract...it is a fail to eject.

A stovepipe will have the case trapped between the breech face and the barrel. A fail to extract will leave the case in the chamber.

Since most semi-autos are a controlled process, meaning the round in thoroughly controlled from start to finish...from the moment it is stripped from the magazine until the spent case is ejected...unlike an AR platform where the process allows the round to be loose for a fraction of time...the parts controlling the round on a semi-auto must all be in synch and working together.

There are three things in play here...the case itself, specifically the rim, the extractor and the ejector...possibly a fourth contributor...the magazine, specifically the top round and how the magazine is delivering that round.

From the pic, it appears the extractor has lost control of the case so the ejector was not able to do its job...but that's a stab given a pic and not more info.

Has this happened before? With what ammo? Magazine make? Maintenance checks?

All quite true and that's why I mentioned it in my previous post.

Its been a long story of issues with this pistol build, but if your looking at the first picture I shared in my OP my guess is that case weakly ejected but hit the optic and bounced back into the chamber area in time to cause the malfunction.
Just my guess. I do realize its really hard to describe things in a forum and plus my own observations might not even be correct.

I have a video I took of me firing a 15rd mag that helped me focus on replacing the extractor. It shows the cases being ejected randomly in different directions with different levels of force... some look like they are slowly crawling out of the gun and just plopping on the ground (not literally, just descriptively to give an image of whats going on).
What was going on.

Yesterday, with the new Glock oem extractor and plunger etc. all the cases forcefully ejected to the right and landed in a nice pile for cleanup.
