I have owned glocks for about 10 years and have had 7 or so different models but I downsized my inventory and decided to only keep certain guns, calibers.

I decided to keep a couple 9mm glocks as I have always preferred them and could count on them to be reliable.

I never had a single issue with any glock, at any time with any caliber but a few months ago something irritating started to happen.
My glock 17, which has about 4-5k through it started to spit brass straight back into my face. My 19, which has 2k or less through it started to do the same thing the very same day. The common denominator of this phenomenon seemed to be winchester white box 124gr fmj. I returned to the range with 115gr and everything went back to normal.

My next step will be to shoot my 124gr HST's that I carry and try an assortment of other brands in different grain weights to see if it was just an isolated thing with that lot of ammo, it just doesn't make much sense that it would but I never had this problem before so idk. I'm a lil bummed out because they have always eaten anything I've fed them...

Anybody else experience this problem? Feel free to share....
 
I looked over the entire gun and everything seemed fit n fiddle but I suppose I wouldn't be able to eyeball a slightly out of spec extractor. It seems to be an anomaly with the 124gr but I'll probably just swap the extractor to be safe.
 
I want to say early Gen 4 Glocks had a rash of complaints about this, allegedly attributed to a new style extractor. The 60+ Gen 4 G19’s we issue didn’t have a problem with this brought to my attention (yet?), but the much larger local Sheriffs office’s armorers said they had a few complaints in both 9mm and .45 ACP Gen 4 guns.

Good luck with your Glocks!

Stay safe.
 
Yeah mine is a 3 gen. Whole world is falling apart. My glock starts malfunctioning the same year my state governor goes and saddles the state with a whole new laundry list of gun control measures, a state that has had virtually no gun laws for the last 250 years is now a liberal gun grabbers paradise, much like mASS, NY and CT... I thought Vermont was immune to this 21st century gun grabbing foolishment much like I thought glocks were free of any defects... live and learn.
 
California of the Second Amendment is happening all over, sadly.

It’s done zilch to slow the crime rate but a lot to make law abiding gun ownership a pain.


Stay safe!
 
My friend bought a S&W M&P9 Shield and liked it until he started shooting his bunny fart target loads. The cartridge cases started hitting him in the forehead. He sold the gun.
 
Ironically enough California seems to be the only state poised to go the other direction on gun control. At least on one issue, for 5 minutes...

I have a friend, a big Glock fan, that experienced the same thing with one of his last Glock purchase, a Gen4 17: for the first couple thousands rounds the ejection was perfect then it started to become erratic.
Pretty much all the videos I see about Glocks, I see erratic ejections every time. And at the range I attempt, same thing.
I always guessed if replacing the plastic pin under the beaver tail with a steel one could help, giving more "rigidity" at the ejector assembly.
 
I did a lil reading, seems sometime around 2006 or so they started using some MIM'd parts. I still have confidence in them, it just bugs me. Never had a problem with any type of ammo and then out of nowhere flaming hot brass to the eyeball. Literally the first round fires straight into the open eyeball.

It is such a common issue with Glocks that it even has it's own acronym: BTF

The most common fix for it is to replace with a REVOLVER.

Maybe he was subconsciously thinking the same thing, posting in the wheelguns subforum. ;)
 
I own one Glock, a Gen 4 model 19. It spit spent cases back at my face pretty regularly with a variety of 9 mm Luger ammo of both 115 and 124 grain made by a variety of manufacturers. Without any modifications it now seems to have grown out of that annoying tendency. I never saw anything visibly wrong with either the extractor or ejector. Maybe it just needed the recoil spring assembly to wear in a bit.

Just think all those years you didnt even know.. It started mid gen-3.
 
I sent my gen 3 19 back to Glock twice for btf & stovepipes. They finally replaced the ejector with a 30274 from a 336 & it's been 100% since. I have a 22 gen 4 that ejects btf sometimes. I think it's a glock thing.
 
That's good info. I might swap it. I was also thinking the ammo could have been from a bad lot with under loaded cartridges and it only happened with that one box but after knowing that they cheesed out on part quality I might just have to swap ejectors. I can't for the life of me figure out why they put so much time and money into releasing new products but cheese out on their existing line.... I hate that, I really do.
 
My gen 3 17 seems to have erratic ejection with Winchester white box ammo. It’s been pretty normal with everything else I’ve tried in it though.
 
I have never experienced this myself through a number of Glocks in all generations, through hundreds of thousands of rounds either fired by myself or by students. I have heard that the gen 4's could be bad about this, but I have a 19 gen 4 that has never done it.
 
I have a number of 17's, 19's, and 26's, Gen 2 through Gen 4.

The only time Ive had the occasional BTF issue, has been with my worn out reloads, where the case rims are starting to go. I have all sorts of malfunctions start to pop up with those lots of brass, and its great for unexpected malfunction drills. Put fresh factory ammo or reloads in the gun, and the problem stops.

I figured that out back when everyone was telling me that it was an extractor issue and I swapped the "bad" extractor (there was nothing wrong with it) for a new one, and it kept right on doing what it was doing before. Once I saw that it was the brass, I ended up swapping that first extractor back, and its now has over 140,000 rounds on it.

Just out of curiosity, have you ever stripped and cleaned the slide? I do that two to three times a year with the two Glocks I shoot each week in practice, and if youre shooting them regularly, youll be amazed at how much crap comes out when you clean them. If youre not doing that, and especially if youve never done it, I would suggest that as a first try at figuring things out.

You also want to make sure youre not lubing the slide internals. That may also add to the problem, especially over time and no cleaning.

In between full strip cleanings, I'll flush the extractor area out with Gunscrubber every now and then. Every time I do, I usually get a good bit of junk flushed out.

Im not saying that the extractor isnt an issue, and its certainly worth taking a look at. But unless its visibly damaged or worn, Im betting it just needs a good cleaning.

I have never completely stripped my slides. I guess I probably should all the while knowing I won't really know if it resolved anything because it was just a flukey box of ammo. I will detail strip/clean them and run a variety of different loads and see if I have any problems. I use to clean my guns regularly but over the years less and less frequently, s suppose that could be a contributing factor....
 
It is a well known fact that many late gen 3 9mm & some gen 4 9mm had issues with btf & stovepipes. I don't think Glock ever admitted to making a mistake, but they sure fixed a lot of their pistols on their own dime. They even tried using the same spring assembly for the 9's & 40's which is never a good thing, especially since the 9's are prone to problems due to weak ammo/new shooters limpwristing.
