I shot my G19 today and had 2 failures to eject. The gun has a little over 2000 rounds through it and these are the first 2 failures I've had. Both were the 3rd round in the same mag, but I shot using that mag again and had no issues. Ammo was federal aluminum, but I've shot at least 1000 rounds of that ammo with no issues.What could be causing this? Here is a bad pic.

I'll hit batches of weird shit happening with ammo too. No real pattern or explanation, but they come from the same box of 50, then nothing is an issue for another case or two. Aluminum? I have had same result from it with the Al case and I have shot thousands of rounds of it. I wonder if it expands differently or the case is slightly out of shape enough to cause the issue. |

Ammo. This was what I figured. That Federal aluminum stuff isn't worth the savings over brass. These are the first issues I have had. And between me and some other guys that I know shoot it we have had hardly any malfunctions. |

Look for sheared extractor hook or gunk on the hook or build up behind extractor. I have seen extractors shear on aluminum snap caps. Make sure your ejector is intact and full length too. The way the casing is crushed between the slide and barrel tells me that the slide travelled back far enough to pull the cartridge out of the chamber yet ejection did not take place. Usually either an extractor or ejector issue. |

Sometimes you loosen your grip, sometimes you anticipate recoil, sometimes you double tap... (He Said Gun had 2k Rounds on it, not in one session) |

I have had that same type of failure to feed in my Glocks using aluminum ammo.
I think it was a combination of weaker ammo and me anticipating recoil/jerking very bad after a log practice session (version of limp wristing I guess) where the casing just didn't quite clear the port. If I wasn't tired, shooting a little bit more stout ammo, it dosnt happen. This also only happens when I use my old bad-era 10 round mags with original followers from 1997. Or, maybe aluminum has something to do with it. It doesn't bounce of the slide wall, ejection port the same as the much heavier brass. Quoted:

The obvious test is to see what happens with good brass ammo.
If that solves the problem, it's therefore an ammo issue. Not to be sarcastic, but the last 1000 rounds of aluminum ammo you shot has nothing to do with the current pile you have in front of you. It's marketed as cheap range ammo at best, and the 115gr variety of aluminum ammo is bordering on junk. I've shot some aluminum, but won't buy anything but 124 gr. |
| Still to early to tell what the problems is if its not obvious such as extractor or ejector. Two rounds out of 2k it could just be the practice ammo a certain lot of it that caused issues. If you have a properly cleaned and lubed gun with good quality magazines and ammo then that should tell you something. |
