My recent production gen 3 g19 that I purchased about 2 months ago(test fire date:6-3-11) was having some serious erratic ejection, and LOTS of stovepipes. I sent it to Glocks head quarters in Smyrna, Ga. When it returned I still had the same issues.
I lost all confidence in this pistol. It was intended to be my EDC. So I sent it in the second time, and explained to them that they either needed to give me my money back, or replace it with a gen 4 g19 with the latest RSA and ejector. He explained to me that he could not make that call, and that he had to ask his boss.
So he called me back 5 minutes later, and told me that his boss said they could swap my gen 3 g19 for a brand new gen 4 g19 other the latest RSA and ejector. That was 1 week ago, and I was told to expect it by next Monday.
So the bottom line here is that its not just the gen 4's that were having issues, its the gen 3's as well. It was an ejector problem. The only problem about the new ejector is that it ONLY fits in the gen 4.
So if you are stuck with gen 3 lemon(not all are having issues), they do not have a fix for you. They offered no fix for my gen 3, they had to swap it out for a gen 4 with the new RSA and ejector. So IMO, buy a gen 4 so if you have issues there is a fix out there for you.
**I am in no way bashing Glock, their CS has been beyond 110%, they paid for shipping both ways, and have made me a happy customer in the end. I give them 5 stars for CS.**
