First 50 rds in my FDE G19 were all in the forehead. I talked to Glock and they sent me a new ejector and a new extractor. The ejector is a 30274. Installed both, ran another 50 rds. I had maybe 5 rds eject correct, the rest were at the 6. Some just fly out and hit my hand. No FTEs which is a good thing. Now since I have parts to mess with I am going to try the "Dave" fix to the extractor. Stay tuned.
My FNX-9 worked perfect.
G17 gen2, FDE G19 gen3, FDE G21 gen4 and a few other black guns.
