I unfortunately had the opposite thing happen. I bought my first Glock about a month ago (gen 4 G19) and finally got to go to the range with it Tuesday. I put 200 rds down range, 100 124gr ficcoli not sure if I spelled that right and 100 115gr sellars. Let's just say my forehead really wishes I had not forgotten my hat. I probably took 50% of the brass off my forehead and I have the marks to prove it. Also with that I had probably 8 FTE and 5 or 6 double feeds. I was not a happy camper! I am hoping that Glock will be able to take care of the issue as I really don't want to spend the money replacing parts.
