Do a search…This is a well known problem, That as far as been peiced together to date, started in/about the 2009 time frame, Glocks made before '09 are pretty much good to go (or so it seems) after '09 you’re rolling the dice…I’m not saying all of them are bad, But the chances of getting one that will work without problem,is somewhat of a gamble…If yours ejects cases out to the right like it’s supposed to, and you have more that 7-800rnds on the pistol Great! you might be GTG, But on the other hand if you observe erratic ejection(ejecting to the left, up over your head, forward, to the right, just over you right shoulder)Watch out, it probably won’t be long before you start getting hit with brass…
One good reason why many have never heard of this problem is this: there is a large number of pistol buyers that buy a pistol…shoot it once or twice or maybe run a box though it at deer camp every fall and that is it.
If this is you…chances are you might not ever see the Glock extraction issue…ever.
Mine did not start doing it until about round number 800. Before that, ejection was weak but never hit me. If you do not shoot very many other pistols or shoot only a few times…you most likely will never notice this as an issue.
It is hard for many of us here to realize that quite a vast majority of people that buy 9mm Glocks do NOT shoot as often or as much as many of us do.
I am not a competitor, but own rural property and shoot there about every other weekend. So therefore, even though I am not law enforcement or a private security contratcor…I do run more 9mm through a pistol than do many casual shooters. I probably run at least 2-5 50rd boxes of 9mm, 40 or 45 through one of my guns every other weekend.
So I guess we have to take this into account: a large number of Glock owners do not shoot very often.
There are probably those that bought the later 3rd and 4th gen 9mm Glocks and had no troubles at all…got to take those into account as well.

Just checked my shooting log, close to 1500 rounds through the 19 and only one to the head. The 17 has less than a 1000 so I will keep an eye on it.
aawwww, that may explain it. I have had mine for at least 8 years. I have shot 1000s of rounds through it and other than changing springs, have not done anything to the pistol.
It even still looks good 
you must have been out of touch for awhile
most recent Glocks produced within the last 2 years have been having issues

I guess I bought my Glocks long enough ago that mine are not in the problem area. I had heard a bit about the Gen 4s having problems, but I had not really heard about any Gen 3 issues.
I haven’t done a ton of research on Glocks since I bought mine… cuz, they are Glocks lol. It’s kind of like researching hammers… I haven’t bought a “new” Glock in years. I did put a threaded LW Barrel on a Gen 3 17 and stuck a suppressor on it, and that caused a couple issues, but I put different springs in and haven’t had problems.
Grant,
Do the Gen 3 Glock APEX have the LCI?
Thanks
No they do not.
My gen 3 Apex extractor is like the 2nd gen extractors.

“Most” is tough to measure. 8 of 8 of our Gen 4 9mms have run well, since 2010 with over 10K rds per year since then and several since 2010 Gen 3 also. Many sadly do not.
