They're not made anymore. You have to look around in local gun stores that sell Glock parts, and examine them closely to see if they're indeed the old investment cast extractors.

Here's my post showing how to tell the difference, the short answer is at the bottom of that post, the new "MIM" extractors have the number cast into the rounded leg of the extractor, the old investment cast extractors have the number cast into the internal spine of the extractor closer to the claw.
http://www.glocktalk.com/forums/show...&postcount=273

LoneWolf brand extractors are investment cast. Though everyone I've heard from who's used the true 9mm version in a 9mm Glock that has the ejection problem with a 336 ejector has reported that their ejection became worse. I've only heard from one person who tried the 9mm version with the 30274 ejector, and he said it ejected much better than with the original "MIM" extractor. Of course 90% or more of people who used the .40 LWD extractor in a 9mm Glock saw their ejection problem fixed. I have yet to hear from anyone who's tried the true .40 LWD extractor in a .40 Glock that had the ejection problem.

Now, let's see, how can I explain this? OK, yes, the new molded extractor claws are slightly too large, and the new extractor claws do a really poor job of gripping the cartridge rim tightly. Consequently, when extraction starts to take place and without that slight angle to the claw, like the 40 caliber extractor has, the case is going to come out of the chamber along a lower horizontal axis.

Something else is going to happen to: Because the inside shoulder of the new molded extractors is slightly oversized, once the cartridge case is almost out of the chamber the new extractors are unable to move backwards into the slide with the same, 'snap' as the older extractors are able to do.

This means that a spent cartridge case is going to be, 'pushed' more out of the gun rather than, 'snapped' out; and THIS is what Nowlin's solution actually addresses. Consequently, there's more than just one performance characteristic wrong with Glock's new molded extractors. If I were to do a list, it would look like this:

1. The top and bottom, 'flats' are too thick and need to be polished down.

2. There is no reverse angle on the earliest extractor claws.

3. The claws on these molded extractors are too large and the fit is sloppy.

4. The inside, 'shoulder' is slightly oversized and inhibits inward extractor motion (or, 'snap') at the end of the slide's stroke.

5. I have a suspicion that the recoil characteristics of Glock's new dual-action guide rod design contribute to this situation.
Arc Angel,
Your very nice summary made me think of something else. If the nose of the claw is too long it can block the closure of the claw on the rim by contacting the inner circumference of the rim before it has rotated far enough. This would stop it gripping the rim until the case was well out of the chamber. That might or might not cause a problem as it "tries" to grip the rim as it pushes the case to the left. It might also explain why the .40 extractor often solves the problem as its nose should be a little shorter.

Another good one, English!

(Do you think Glock, GmbH, is ever going to give us a discount, or something, for figuring all of this stuff out for them? I don't know about you; but I'm dizzy!)

I'm sick with a spring cold......Robitussin is my best friend.

When I glanced at this thread title, at first I thought it was an ad about ED from Viagra or some such drug....

I have both a 26 and a 27, no problems at all with the ejection on the 27 - it really flings the empties! The 26 though ocassionally flipped an empty to the left or dropped one on my head - I usually shoot WWB 115 gr. at the range, given that ammo I wasn't surprised. I enjoyed reading this thread, and thought I'd give the "cure" a try.

I took out the extractor on the 26 and polished the top and bottom with a stone then finished off with a couple swipes with 1500 Wet & Dry paper. I also worked the 1500 grit paper over the inside of the hook. I then put the business end of the extractor plunger to a slow running felt wheel and polished the end nice and bright. I was surprised too see some copper traces on the end even after I polished it. It must have been some of that C5A lube acutally worked itself into the metal.

Anyway, with the polishing completed I reassembled the slide and found the extractor hook moved much more freely in the slide. I tested with some dummy rounds and they ejected nicely. Today I ran a few mags through the 26 and every case ejected right at about 4 o'clock. They didn't fly to far - about three feet - but again it was WWB ammo - not very hot.

More shooting will tell the tale. I ordered some of that cool copper anti-seize and will put a tiny dab on the plunger, and extractor hook. Figure that can't hurt and unlike other lube it sure looks pretty.

I may just have to put the "cure" to my 27.

Both the 26 & 27 are pretty new 3rd Gen - no more than a year old. They have the LCI extractor.

Oops! Guess I needed to read that closer ... the ejector in my 26 is a 336.

no prob at all, thanks for the info.

wondering why they still use the "old"-style ejector 336 instead of the "new" 30274 in the newest gen. 3 glocks, but okay hundreds of thousands of glocks perform perfect with the "old" 336 ejector

Bought a gen3 G34 a few months ago, because at least a couple brass hit me in the head from every mag I run through it I have been watching this thread closely. I stoned and polished the top and bottom of my extractor which made no diffrence. This thread is barely a month old and is on its 13th page of 313 replys.....obviously there is a problem here.... if Glock is fixing guns that get sent back to them why are they not putting together kits with good parts in them to send to their customers? Its not that I am against tinkering with a gun to get it to work how I want it to, I do however think that I could expect a company using "perfection" as their slogan to supply me with a gun that does not bounce hot brass off my forehead. I would even be happy to tinker with the edjector and extractor myself, but don't want to purchase the R&D "test" pieces and don't want to get too carried away modding the stock pieces. I guess I just need to ship it back and let them deal with it..... dont get me wrong, I love my Glock, just cant believe this is being allowed to carry on so long

My glock 34 is a 12/11/2011 gun and I was having serious issues with ejecting as well. I tried everything listed here and then some, the only thing that finally fixed it was a Lightning Strike stainless guide rod with a 14 lb. spring

what i don't understand is, that in the US you have to get your spare parts / replacement parts being shipped to a glock certified gunsmith (otherwise you won't get them directly from smyrna, if i got it right you can't get them shipped to any other gunsmith (not glock certified) and even not to yourself at home, right? why that, would it make much easier for all people involved, especially with non-critical parts like ejectors/extractors etc.

in europe you can get the parts shipped to your home directly from glock austria (also they are no longer as generous with spare parts as in former times, seems the company policy has changed somehow).

Reading this thread and alot of others about sloppy ejection leads me to think that Glock Ejection Failure is a combination of factors that encompasses parts, ammo and shooting technique.

I notice alot of difference when shooting premium ammo vs the WWB I normally fire at the range. The expensive hollow points really work the pistol. But I'm not going to shoot that stuff much at $20 for a box of 25!

I have also noticed that ocassionally when shooting "fast combat" drills, my grip will loosen or change and that can effect ejection. That is a technique problem, and totally my fault.

I would prefer not to polish up parts to make firearms work nicely, but it's pretty easy on the Glock. I don't like having the original finish off the top and bottom of the extractor, but if it makes a SD pistol more reliable, I can sure live with that.

Sadly, I recall the days when S&W revolvers were the weapons of choice. Most everyone in the 1970's lamented that their S&W couldn't hold a candle to the slick revolvers of the 1950's and 60's. Today guys are breaking their necks in mad scrambles for basic M&P's that 40 years ago no one looked at twice.

For now this "cure" seems to work in my pistol. I will keep a close eye on it - and this thread for newer developments.

One other item: After polishing the extractor and the face of the plunger and reassembling the slide. I used a toothbrush handle to push the extractor back and forth in its slot, making sure it was free to function properly. I suppose you could try that in your pistol, assuming the extractor is free to move - it is possible the source of your ejection problems lies elsewhere.

Someone recently posted a "torture test" video where they buried a G26 with one of the new extractors in dirt. Parts of the slide and barrel were rusted, but the extractor wasn't. I believe these new extractors may be stainless steel.

The old investment cast extractors are definitely a carbon steel, when I found one of them in a local gun store it was caked with surface rust, it's a non-LCI 15 degree so it was probably sitting in the little zip-loc bag that it came in for 10 years or more. A quick scrub with solvent and a phosphor bronze brush made it look like new though.

Well, I have polished the top, bottom and back stud on my extractor and my G34 is still slinging brass all over. I do not think the extractor is the issue with my particular gun, it has never felt tight and has always fallen out by itself when taking the gun apart. Glock is suposed to be sending an old style extractor to my LGS for me, I'll put it in and see if it fixes it....I have my doubts though after seeing no results from the changes I have made.

Looks like it worked

So I could not resist doing two changes at once: polishing both sides (top and bottom) AND cleaning the claw. Whatever had caused the issues, they are now gone. No more stovepipes, no more jams, nice ejections to the far right, no more head cover needed.

And this is what the extractor looks like now, after just a few gentle runs over an Arkansas stone:

Just for the record, I did not polish or sand this area:
General Glocking
To the left of the indicated line, this area was all black (I retouched the image to reflect this). Below is what it looks like when only cleaned:

General Glocking
There are (shinier) high spots, a long one on the left, one in the middle. I would have thought that those would need to be sanded, but I didn't. Doing just the top and bottom a bit fixed my issues.

So, thank you for bringing this up and for pin-pointing to just the top and bottom.

Just another confirmation - Lightly filed the top and bottom of the ejector. No problems since.

G26 problems

I bought a new G26 test fired in Jan. 2012. Put about 80 rounds thru it and was peppered with brass to the face and head. Probably 20-30% hit me somewhere. One flew directly back and smacked me on the eyeglass lens. When I started reading this thread, and I have read it all, I pulled the G26 apart and polished up the extractor on both sides and just hit the step a few strokes. The extractor easily falls out of its slot where it would not come out before. I had to pry to get it out at all. So I hope this works, I have not shot it since the polish work but hope to this weekend.
I would like to know where to order the .40 extractor from, in case this does not work. If someone could direct me I would certainly appreciate it.
I will keep you guys posted.

lone Wolf distributing sells the extractor most people want. Last time I checked they were still on backorder.

the .40 glock OEM extractor should also work perfect in the 9mm glocks, so if LWD has them not in stock, perhaps a glock OEM extractor .40S&W will do the job also.

sometimes only changing the ejector is necessary, sometimes only extractor, sometimes both (and sometimes even that won't cure the prob, but in most cases it will)

I finally got out today to do a little experimenting with different extractor/ejector combos. I have two Gen4's to mess with:

G17 with 336 ejector and 012 RSA

G19 with 30274 ejector and 043 RSA

I've been running a .40 LWD extractor in the g17 for around 600 rds and ejection has been pretty consistent around the 3-4 oclock area. The g19 had pretty inconsistant ejection right off the bat and was slinging alot of casing towards my head/shoulders so I polished the top,bottom,and step on the OEM extractor and ejection got alot better with most casing going in the 4 oclock range. I still get one occasionally that goes towards my shoulder, but the casings come out of the gun with a high enough arc that they go way over my shoulder.

Someone asked if I would swap extractors betweent the two guns and see what happens. So here are my results:

The g17 with the polished OEM extractor went back to it's old habit of really erratic ejection with one casing going to the left.

The g19 gave the same performance with either extractor.

I only ran 20rds through each gun with the other extractor in place, but it was enough to notice the difference in ejection. I have a 30274 ejector on backorder at glock store and when I get it in I'm going to put it in the g17 and try the polished OEM extractor again and see if it will run with that combo as good as it runs with the .40/336 combo that it has now.
