Anyone? I'm getting triangular shaped scrapes on the spent cases from one of my glocks, and woukd like to see if this new ejector corrects this issue. Other than that, all of my glocks eject just fine. Never a single spent case to the face. Strong reliable 3&4 o clock ejection.

These are the only two retailers confirmed to have it so far(backordered), the other retailers presumably have the old version with the 336 ejector:
1. http://www.midwayusa.com/product/225860/glock-trigger-housing-with-ejector-glock-9mm-generation-4 2. http://glockparts.com/Detail.aspx?PROD=123022&CAT=748 If you continue to experience erratic ejection with the 30274/28926 ejector, it means your extractor is out-of-spec. Keep the new ejector in the gun and replace the extractor. Those are Gen4 9mm trigger housings. If yours is a .40, you'll need the 28926 ejector which hasn't been confirmed to be sold by anyone yet. Because this is a Gen4 trigger housing, if your gun is a Gen3 you'll need to remove the old ejector from your Gen3 trigger housing and do the same with this Gen4 trigger housing, then install the 30274 ejector into the Gen3 trigger housing to use in your Gen3 gun. Here are instructions on how to do so: Remove the trigger housing from the frame, grab the ejector with a pair of pliers and pull it out of the trigger housing, then insert the new ejector. Be careful not to bend the ejector to either side because the slightest change can either adversely affect ejection or put the tip of the ejector closer to the primer of a live round being ejected which would be dangerous. (I wrap the teeth of the pliers in masking tape so the ejector doesn't get gouged or scratched)

No, the three glocks I currently own are all 9mm. A G17, that I bought back in 2003-4, a G26 purchased last year and a G34 purchased this year. All of them are gen3 guns and all of them have the 336 ejector and the LCI extractor in them. Never a single jam with either of them. STRONG RELIABLE 3&4 o'clock ejection patterns, neither of them never spat brass to my face. Given the -only- issue I'm getting is these triangular shaped scrapes-dents on the neck of my spent cases, I would call this a non issue, EXCEPT, it shound'd be doing it (the 34 is doing it for sure, and the 17 might be). Checking some old brass from my reloading brass bucket, I noticed some scrapes given to the brass by the G17 too. Now, I know for a fact, becaused I checked, that the glock 26 is NOT givin my brass these scrapes dents, so, next time I go to the range, what I'll do is swap extractors. I'll take the extractor off the G26 and I will drop it in the G34. See how that goes, and after doing this I still get the dents-scrapes, Im gonna think either it's the ejector in conjunction with the extractor making the brass to "touch" the slide on its way out of the ejection port OR that the slot on the slide of my G34, where the extractor sits, is out of spec slightly. If I had to bet money on this, I'd bet its an EJECTOR 'issue' Does that make any sense to eliminate variables? HTR HTR. |

Other than exacerbating your OCD, what's the harm in those little marks on your brass? You've stated that all your Glocks perform perfectly.  OCD? Close to perfect, not quite if they're leaving these marks on my brass 
HTR. ETA: oh!, you mean Obsessive compulsive disorder? it is the fuel to perfection bro!

Those triangular scrapes are characteristic of the erratic ejection problem, my Gen3 G27 was doing that too. After the new ejector they're gone.
Some people have fixed the problem simply by replacing the extractor, suggesting that they simply got an out-of-spec extractor. Others like myself however found that only the new ejector would fix the problem. I used an extractor from my G23 that doesn't have the problem, and it made very little difference. I compared how each slide held the extractor from my G23 that had good ejection. With that extractor in the G27 slide, I could see a noticeably bigger gap between the claw of the extractor and the breech face, both with and without the rim of a spent casing under the claw. Also the forward portion of the extractor with the claw on it seemed to sit a little further outward from the breech face(without a spent casing). And the tension with which a spent casing was held to the breech face was noticeably less in the G27 slide. This suggests to me that the cut-out in the slide which holds the extractor is out-of-spec in the G27 slide. From what I can tell, the extractor isn't firmly holding the rim of the spent casing to the breech face, so the casing is allowed to drop lower in the gun. The bottom corner of the extractor claw is still forward of the rim, and when the ejector hits the casing, the casing pivots right and the case mouth smacks into the slide just below the ejection port opening. That causes the triangular dent/scrape. Then the rim of the casing comes out from under the extractor claw early and the casing bounces around in the ejection port any number of ways before either leaving the port in an erratic fashion or in worst cases causing a failure to eject. |
