Keep your chin up. Hopefully you will get it running right. I appreciate you starting this thread. The use stronger ammo crowd, limp wristing etc. is getting old.
My Gen4 17 went back to Glock at 1500 rounds and had the ejector replaced. I got it back and fired 300 rounds through it and the issue was resolved or so I thought. I went out today for another 200 rounds and I had a stove pipe. Exactly the same type I had between 1000 and 1500 rounds.
The good news is the brass to the face issue was resolved with the ejector. Glock needs to swallow some pride and go back to what they were doing right. Something worked up until 2009 or 2010 and whatever THEY changed, they need to change back. It is that simple.
