Hi! I have a new Glock 34 Gen 4 that I received directly from the factory two weeks ago. I took it to the range to get accustomed to it and ran about 500 rounds doing various drills and about 200 rounds today shooting a steel challenge match. All of the ammo has been 115gr Federal 9mm. So far, I've had frequent failures to extract persistent weak extraction. Extraction is extremely weak when shooting and when simply racking the slide with a chambered round. Empty cases don't go more than about 2 - 3 feet and when unloading to show clear, chambered rounds barely cleared the breach. Is this a common problem? Is it a matter of breaking the gun in? |

Does the pistol have the latest ejector, 30274, or the old 336 ejector? Most likely the new ejector if you got it two weeks ago from glock. Federal Champion 115g is about the weakest 9mm ammo you can buy. You are going to get weak ejection, but it should still eject. Have you shot any other type of ammo? I would call Glock and see what they have to say. |

If the case mouths of the spent casings have triangular shaped dents/scrapes on them, it's a common problem in recent production Glocks. Look at the number stamped on the ejector. The newest ejector which will help fix the problem is stamped 30274 for 9mm. If your gun has the 336 ejector you should try to get the new 30274 ejector.
If you have the 30274 ejector, try replacing the extractor with another 9mm Loaded Chamber Indicator extractor. |

Eventhough my gen 3 G34 has worked flawlessly for 400 rounds, I am getting these dents-scrapes. It's a late production gen 3 G34 with the gray finish on the barrel and a 336 ejector. Oddly enough, all my other 9mm glocks have this same ejector and they don't give the spent casings these dent scrapes marks  . The pistol's been 100 percent reliable so far. I'll take pics of the spent casings later.

I'm gonna say it again, this dents are the ONLY issue I've seen so far with the gen 3 G34, other than that it feeds, extracts and ejects like a charm. Not a single malfunction of any kind. But I'm too anal not to worry about this. Do you think swapping ejectors would help getting rid of this "issue"? HTR. |

No, I think swapping EXTRACTORS would get rid of the issue. My understanding is the new Gen 4 G34's have the latest Ejector already. Get a Lone Wolf extractor. |

No, I think swapping EXTRACTORS would get rid of the issue. My understanding is the new Gen 4 G34's have the latest Ejector already. Get a Lone Wolf extractor. But my G34 is a gen3 with the OLD ejector. Im not arguing, just making sure I swap the right part. The pistol in question is a latest production GEN3 GLOCK 34 with a 336 ejector and its giving the spent brass these triangular dents-scrapes (pictured above). This is an EXTRACTOR issue and not an EJECTOR issue. Correct? Just asking because neither of my older 336 ejector 9mm glocks is having this issue at all. The ALL have LCI extractors, but the G34 may have the latest production EXTRACTOR and maybe that's whats causing the problem. I may swap extractors between the GLOCK 17 (bought over 8 years ago) and the 34 just to make sure before buying a new extractor. This way I can at least eliminate THAT variable. Does that make any sense?

Can you describe the failures in more detail? Sure. I'll see if I can film the failure this week. That would help, but all you really need to do is elaborate on what is happening. For example, Failure to Extract means the empty case is not being pulled from the chamber. Is that what is happening or is the empty case being pulled from the chamber, but not leaving the weapon? |

Yes that's what I'm talking about.
The people who had success with LWD extractors were unknowingly using .40 extractors in their 9mm Glocks, when LWD first started selling them they had their 9mm and .40 extractors mixed up with each other. The .40 extractor works better because it holds the spent casing closer to the breech face and has a rearward angle to the claw which acts to raise the case mouth of the casing earlier during ejection. The new ejectors do the same thing, they raise the case mouth earlier during ejection. What fixed the ejection in my Gen3 G27 was to get a new extractor and install the new 28926 (.40SW) ejector. The extractor didn't make much difference, the ejector made a huge difference. |

It is possible that you have a bad extractor, but I would try removing the extractor and spring loaded bearing and clean them and the channels they reside in really good. Also, look at the extractor hook to see if it is chipped. |

To the OP.
Did you ever tell us what ejector you were rocking? I didnt find it in the thread but may have skimmed over the information. You did say you just received it from the Glock factory two weeks ago so it SHOULD have these parts but who knows these days. Also, clarify your issue. Are you having weak EJECTION or failures to extract? There is a pretty big difference in that particular parts, either the ejector or extractor are NOT involved necessarily with either problem or may be independently the problem part. Get back to us with more detailed info. The first thing i would do is check to see if you have a 336 ejector in the gun. If you do, call Glock and tell them that they need to get a 30274 ejector to you as of yesterday. They will hem and haw but at the very least, send it out to an armorer. Good luck, this can be frustrating but it CAN be fixed. |
| Glocks are not strong ejectors and, on the surface, it doesn't sound as if the ejector is the problem. The real question is whether or not the ejection is consistent meaning do the empty cases generally go in the same direction or is the pattern erratic. The 336 ejector has been in use for a very long time and I'm not convinced it's the root of the gen 4 issues. The extractor and recoil spring assembly seemed to be the cause of most of the problems as those are the only things that were changed. |

Thios is true Brad but the 336 Ejector was always on the marginal side. I have a 07 and an 09 Gen 3 19 and they will still put the occasional case into my cheek and will put them into the top of my hat routinely.
I believe the new Ejector is a step in the right direction but the MIM Extractor is likely the biggest culprit. Hopefully, the new Ejector in combination with a better Extractor will unfuck this. |

I agree. My older gen 3's have thrown the occassional stray case, too. It's just amazing how this has gotten whipped up into an internet frenzy. In the OP's case, I would replace the extractor before doing anything else. |
