Also, see if Glock changed out your slide lock springs. They also have been known to cause issues with the Gen4.

Could it be the ejector? What number is on it?
2007 or earlier? Where was that number pulled from?
All the newer Glocks I bought were built after that date, and I only ever had problems with a couple of the Gen4s, which got resolved, and my G26Gen4 worked fine from day 1. I also have a newish Gen3 G34, works great.
I do agree though that there has been evidence that their QC is slipping- they're probably falling into the same trap Sig, Kimber, etc, are.
I feel bad for the OP, it looks like he is getting the run-around. These intermittent problems are the worst to diagnose, too.

There's nothing wrong with that ejector. Some recent production Glocks, Gen3 and Gen4 9/40/357, have had a problem with erratic ejection caused by the extractor not firmly holding the rim of the spent casing to the breech face. It can be caused by an out-of-spec extractor which can simply be replaced, but in some cases using an extractor known to work properly in another gun doesn't fix the problem. I had a Gen3 G27 that had the problem, replacing the extractor with one known to work properly didn't fix it. From what I can tell, Glock machined the slide incorrectly, the cut-out which holds the extractor is positioned too far forward, and the forward portion of the cut-out wasn't cut deep enough into the slide. Using the new .40 28926 ejector fixed the problem.
I wish somebody at Glock would get a clue. Ship a replacement frame to a dealer who understands the compliance BS, ship the rest of it directly to you.
