I took my G19 4th gen back to Glock yesterday afternoon because of the stovepiping issues that everyone seems to have with these guns. My gun already had the newest recoil spring assembly but still had these problems. When I picked it up this morning I was told that they had installed a new ejector assembly and that my gun was the first in the US to get it. Hopefully this is the fix we've been waiting for on the Gen 4 guns. The part is numbered "30274". I'll post some pics when I get home.
