Glock Extractor Issues Gen 4 - Gen 3

[Gary1911A1]

It *seems* from reading more than a few of these threads that those with Gen 3 G19's with the 336 ejector that run well (meaning no malfunctions) but exhibit erratic ejections (although not to the point of brass to the face) have found that the .40 extractor (either LW or OEM) that their ejection has become more consistent at the 3-4 oclock. My G19 fits into this category, I just received my .40 extractor today and installed it into the slide. Plan on testing it out this week.

I'm looking forward to your report too.

Combo 2
RSA: 0-4
Ejector: 336
Extractor: OEM 9MM "Dip"
Symptom: Erratic ejections, stovepipes

Combo 3
RSA: 0-4-3
Ejector: 336
Extractor: OEM 9MM "Dip"
Symptom: Erratic ejections, stovepipes

Combo 4

Combo 5

Has anyone had success with filling their 336 ejector?

I did it myself (filed back, changed angle) after having given up hope on having a working gun. Unfortunately on the last range trip I only had a chance to fire 107 rounds, but every round fired 3/4-o'clock to the right. I even was playing with limp wresting. Plan to get a lot more time in before I claim success though.

As previously stated my Gen 4 G17 returned from the factory for the 2nd time and still ejection issues (not many, but still occurring).

Installed the 40 extractor and 200 rounds downrange today, had a few that ended up at 8 oclock, the VAST majority 3-4.

An 8 o clock ejection means the casing hit the ejection port wall right?

That is what I believe, can't imagine any other way.

I will be shooting 200 rounds tomorrow (all that time allows). 100 of WWB and 100 of Remington UMC Yellow box. I decided to break out the calipers and measure the case rim thickness. The WWB comes in right at .90mm which i believe is exactly what the cartridge calls for, the UMC seems to measure in the 1.05-1.07mm range, this was just a random sample of a few rounds out of each box. We'll see if this makes any difference with extraction tomorrow with the new .40 oem extractor.

just installed my .40 cal extractor in my g26. going to put some rounds through this week.

I bought a gen 4 glock 19 Saturday, finally got around to putting rounds through it this afternoon.

Good news, this is my first glock, and I shoot it well. That's a big plus for me quite obviously
Fed 15 rounds of Speer Gold Dot 115gr jhp perfectly, but with erratic ejection

Bad news, in 150 rounds I experience extremely erratic ejection (over my head, 1 o'clock to 6 o'clock and everywhere in between, hit me in the left eye (eyepro saves eyes!) and landed on my right shoulder often)

Also experienced 8 FTE stovepipes and the case stuck between the barrel shroud and slide horizontally.

That is not acceptable whatsoever for me. I'm going to put another 150 through hopefully this week. If no improvement's are seen I'll be contacting Glock.


Disclaimer: I did clean and lube this pistol before firing

FMJ ammo used was remington umc 115 grain (not the best, I know)

All failures were with fmj rounds

Did you file it down to the same profile as the new ejector I'm guessing?

Try the OEM Glock LCI .40 extractor from Glockmeister, seems to be working well for people. I'm waiting on mine right now, I hope to have it by the end of the week.
