Any Glock armorers or school of hard knocks ppl out there experienced with ejection problems? I might have it narrowed down to when im using an extended mag. Not sure. Seems to be when it happens. Hot casing will hit me in the forehead, go down the front of my shirt, or land between my eyewear and skin, once on my damned eyelid!!! Anyway, where do i start?
My theory is the Glock extractor have generous clearance between the breech face and extractor hook.
If the extractor is gummed up or too tight combined with a weak extractor spring, the extractor may not properly extract by having the fired case not firmly held.
My G19 gen 3 extracir was same or very similar to my G26 gen3 extractor except the G19 had much more surface coat on it .
So I flitzed the shiny surfaces and made sure the spring was strong.
I figured if I ever had problems I would replace the spring and bearing.
That is my observation based on my two blocks. Others may be different.
3) If steps 1 and 2 don’t work, get an APEX extractor and the two OEM parts they recommend. The apex is one aftermarket part I was impressed with. It will make most any new Glock eject Brass in a pretty, symmetrical stream.
4) If none of the above work, there’s another part called a White sound HRED ( or something like that); I have no personal experience with that part.
FWIW I trust the apex extractor enough to use it on my nightstand gun
Not necessarily. That's what everyone was telling me in 2013. I'm a big guy, I didn't need to grip harder. I sent it to Glock on their dime with video of the brass pelting me in the head. They called me up and confirmed that it was pelting them in the face as well. They finally called me back again and said the extractor was out of spec. They replaced it and it was good to go.
A weak magazine spring can cause erratic ejection, the top round in the mag or the follower support the bottom of the casing during ejection. If it only happens with that magazine I wouldn't worry about it as long as you don't experience malfunctions with that magazine, if you do then get a new spring for it. If it happens with all mags then putting a Gen4 9mm 30274 ejector from a Gen4 9mm trigger housing into your Gen3 trigger housing along with installing a 9mm non-loaded chamber indicator spring loaded bearing might fix it. If it's still not satisfactory keep those two parts installed and also install a Gen3 9mm Apex extractor.
If the gun is new or very low ammo count, try using more powerful ammo. Make sure the gun is clean. Check magazines and change out mag springs. Enjoy and be safe. Good luck.
If it only happens with extended magazines, I would start there, with the magazines. What brand and capacity are giving you bumps on your forehead?
If you are unsure, it probably would save you the most time by nailing that down as a certainty. The more scientific you are in your testing, the quicker the fix will come (and least amount of money as well).
Glock mags? I know if you fire a GLOCK with no mag, it'll drop the spent case out the bottom. The magazine does affect ejection. I personally have had no such problem with extended magazines, but who knows
Btf (brass to face) is common with gen 3 Glocks. You can buy a apex extractor and non lci bearing or, buy a gen 4 trigger housing and swap ejectors from the 336 to the 30274. I did both on a gen 3 17 never got btf again.
I have given up trying to eliminate all the brass to forehead issues. If there is nothing wrong with the extractor and all the parts are current, and it does not happen with a very high frequency, I just wear a hat and deal with it when it happens. Several of my Gen 4 Glocks do it on occasion.
No one complains that the gun is loud when it goes off and makes you flinch... why complain when it drops brass on your head, but otherwise works fine? Like complaining that the AR is dumping brass on the guy laying next to you, or splitting the drywall at the muzzle.
Many factors to this, as already mentioned...even a change in ammo will change the ejection pattern.
Few yrs back I bought 2 brand new g19s gen3 that both had erratic ejection issues 1 of them was so bad every now and then it would try to stove pipe .
Gen 4 ejector helps but if you want it fixed properly then I would use the gen4 ejector ,apex extractor, the LCI apex recommends and fit the apex extractor per apex fittings instructions. Fixed both g19 perfectly.
I guess you learn something new ever day, but this is one that I will need to see before I believe it.
When testing a different load my favorite mag is a 22 rd.. I load it and then fire four rds. eject mag and fire a fifth round. Then repeat with three of my other Glocks [27, 23, 22, 35] that ensures that they will function and are accurate. So this is something I do regularly and thru 250,000 rds I have never experienced this. You would think that it would be common knowledge if it happened frequently.

Never heard of it happening in the .40 s&w just the 9mm's . And to add to that I've only seen it happen in the later model gen 3 in the time frame that the gen4s were coming out I've seen some reports in it happening in early gen4s but all the gen4s I've come across have been satisfactory or better on ejection .
My personal opinion is that something was changed in the production line when the release of the gen4 and it mostly effected the late model gen3s that were coming out at that time period and have been quietly fixed since then.
If my gen 3 g19 and g26 had this broblem btf I would buy a new Glock oem gen 3 extractor and try it out.
Looking at high speed videos showing slow motion cycling and extraction it appears to me that the gap between the extractor a breech face could be too much and thus does not hold the spent cartridge case tight enough for consistent case extraction.
I for one don't watch hicok's videos as I find them long winded and boring. I only saw one case that may have fallen out the mag well. all the others ejected from the gun normally. I have Gen2's 3's and 4's. Never had a stovepipe without a mag in place.
In all my Glocks I have replaced one extractor that was chipped and did create stovepipes. Maybe it is time for a little maintenance.
If this is a known problem why are millions of Glocks used by the worlds police and militaries not making their recruits aware of this possibility if they need to make a tactical reload with retention and then needing to fire a shot without inserting another mag?
Because glock won't acknowledge it, the problem is real but It seems to be fixed,it was early gen 4 only from what I understand,and just because you haven't heard about it, or because it didn't happen to the 3 guns you own doesn't make it not true lol,just google search it? I think you need to quit being so naive
My kid got a Gen 3 to run Carry Optics Division in USPSA. It was beating the **** out of the new Docter dot, so he put in an Apex extractor and gen 4 ejector. All good now.
If the clearance "gap" between the extractor and breech face is too generous then the case is not securely held. Thus could affect both dropping thru with out the magazine and or btf.

Wow that sounds really scientific. How did you calibrate that "favorite 22 rd." mag, and how does it relate to all the other random mags you insert into your various guns.
There is a lot of mumbo jumbo, and downright poor logic here in this thread. The same conditions for perfect ejection for one person and their specific ammo, and specifics in their personally owned handgun, will cause "poor" ejection in with another person-- and the other way around also.
There are too many permutations: starting with the shooter. Change one variable at a time...if it is still poor, could be the defective shooter(s).
If the clearance "gap" between the ejector and breech face is too generous then the case is to securely held. Thus could affect bot dropping thru with out the magazine and or btf.
How did I make the conclusion of the effect of glock extractor clearance.
Engineering judgement and some informal checks.
I tried out moving a spent case in my G26 and G19 gen 3s to see how tight the extractor was, similar to a 1911 extractor tension check. I noticed some variation between the two yet both of my glocks held the case tight so my two ejection was OK.
Sometime later I ran across the Wavelength1970 channel that has many slow motion videos and noticed the apparent tendency of glocks to have the spent cartridge bounce around the chamber more sometimes as compared to a M&P or some SIGs or Walthers and even 1911s.
I did not notice this until viewing these videos numerous time at the very slow speed portion and looking at the feed cycle and then the extraction cycle. I noticed this only with the super slow portion of the videos. I was at first more interested in how the ammo loaded from the magazine but noticed the different ejection patterns.
Glock 19 toward end of video at slow speed notice how the spent cartridge bounces around in the chamber. The extractor does not hold the cartridge case very tight.
Wavelength1970 channel has videos of various manufactures and models recorded in slow motion.
Is this scientific? no. Is this definitive to all glocks? no, is this an observation that applies to my subset of two glocks and the batch of slow motion videos I viewed?, apparently yes.
At least enough for me that if my glock started to mess up its ejection even after good strip and clean I would put in a new OEM extractor and spring and bearing. I would probably not need to change the ejector. But that is my two glocks with their particular dimensions.
Regarding the drop through the empty magwell, I had this sometime.
also but with a magazine in the madwell it is is not a problem.
When unloading I remove the magazine first then pull the slide back fast enough so the extractor pulls and the round and it hits the ejector. Rarely does the unfired round drop through, but it has happened if pulling the slide very slowly,
Im a stickler about extraction,especially with gas systems,it tells you a lot about what is going on,in a glock the extractor is the weakest link,and as for the brass falling out of the bottom without a mag,it could be a problem on a fast reload bot likely but it can happen,I know it beat the snot out of my Trijicon rmr, im honestly glad it did because I wouldn't have bought the apex extractor, im 110% happy with it, the apex is a better part than glock oem in every way possible and it has a lifetime warranty on it
With the RMR putting the Apex is a good idea.
If I had an rmr I would likely do the same.
With no optics and on my two particular Glocks the OEM parts work ok.
We had this same problem with one of our department issued guns (19 gen 3). Through trial-and-error I narrowed it down to the extractor itself although we went ahead and replaced the EDP spring as well. The extractor looked fine but when replaced the problem was solved.
