Jammed Glock ???

Also at the gun range this past Saturday…

One of the students getting his concealed carry permit was using a brand new Glock. He said it only had about 70 rounds through it.

After about 10 rounds it was the second magazine at least. His gun jammed. Bullet in th chamber, just about 1/4 inch out of battery, less actually. Just a little bit.

The instructor tried to get the slide open? But nothing moved at all.

I peeked over his shoulder watching.

Another student said he’s heard Glocks will jam if you load a magazine to capacity.

The instructor of course had first tried removing the magazine.

The student had another gun. A Sig 365.

The ammunition was factory Blazer ammo. I think it was brass, but not 100% on that.

I don’t know what model Glock. It wasn’t a 19. Something with a longer barrel.

Weird.

I have a Larry Vickers edition G19. Before I place a gun into the capacity of either EDC or home defense I run at least a 1000 rounds through it, all types, especially the chosen round that I will use (Usually FED HST). I never had an issues with the G19.

I have a G40 (10MM long slide/MOS) that I used (hopefully will again) for hunting. My hunting guns I do train with but I will admit that I usually select a round, site it in and once sighted in practice at various ranges. I use Buffalo Bore Heavy 10mm 180gr JHP almost exclusively when hunting with the G40. I never had an issue.

There all types of complete recoil spring packages you can buy for tuning a compensator/ammo to a pistol, usually if a compensator is in use. Especially Glock. Some brands sell packages with color coded springs with different weights. The couple times I've come across Glocks having feed issues I discovered the shooter had changed out the recoil springs with one of those packages and selected their "favorite" color....the colors are for identification, not aesthetics.

Also, many folks for some reason are perplexed on the disassembly/reassembly of Glocks for some reason. It's possible the recoil spring assembly was installed incorrectly. That can and will cause malfunction. In fact as Kevin stated it was difficult to break down by the "instructor" I bet that was the issue.
 
Glocks will jam(especially when new) if you limp wrist them or if you’re using ammo that is slightly underpowered( Winchester White box would jam mine). Try some Fiocci or Sellier and Belliat. Lock the elbow and wrist using a firm grip. Put 500 rds thru it doing this and you’ll be well “broken in”.
 
I wrote this mostly because I thought Glocks were pretty good about not jamming.
Virtually every semi-auto handgun (as well as rifles and shotguns) can jam for a variety of reasons (some shooter induced such as limp wristing). My Glocks have been nearly perfect during the 20+ years we have owned our 19s. Little bits of metal shavings, powder fouling, etc. can contribute to a jam but we have not experienced it.

Possibly a defective cartridge. I’ve seen a factory cartridge that had the case folded over as the bullet was seated. Like this:

Got to thinking a bit more. Does the Glocks require a pull of trigger to release the slide like my S&W SD9VE requires? If so and instructor doesn't know this, maybe they got stumped about how to do a takedown to unjam, by not allowing the slide to be removed.

Only other thing that could cause a total lockup would be a part broke inside and jammed around the slide, sear, or bolt system, that now requires more skill and the right tool(s) to break down without scarring up the exterior finish.

Good luck

Well, that'll certainly do it. It looks to be ripped all way down to bullet tail. I don't think with a case defect like this, that it could even be chambered, but when it comes to Bubba's, anything's possible.

Even a FNG to shooting would not load a round like that in a magazine.....you would think.

If a "instructor" at a range doesn't know the break down procedure of a Glock they have no business being an "instructor" at a range. Holy smokes....Glocks are pretty basic.

There are many reasons. As I stated before the only locked up Glocks I've come across were assembled incorrectly or using the wrong recoil assembly.

Contrary to popular belief, Glocks will jam.
 
ALL guns will jam.
But more often than not, an outside source is the cause.

Reloaded ammo
Steel cased ammo
Limpwristing
Aftermarket mags
Damaged mag
Lack of cleaning
…..and more ….
 
I have a few Glocks in various calibers and have tried to induce a jam by " limp wristing " the guns and never have been able to get them to jam. By limp wristing I mean holding the gun as loosely as possible and still pulling the trigger. I am not denying that other may have had that problem.
 
I just had my Glock 19 jam when I was renewing my CCW back in April. I’ve put several thousand rounds through the gun and it’s been flawless, I still have the utmost confidence in it since it’s worked perfectly up to that point, but all guns can jamb and you have to train for it. In this case it was a catastrophe failure, if I’d been in an altercation the gun would defiantly been out of the fight. In preparation I’d cleaned and lightly oiled the gun the day before, the ammo I was using was brand new unopened boxes of 9mm, 115gr. FMJ Fiocchi. During my qualification I’d already fired a couple magazines through the gun when the slide failed to close on the next round. The cartridge was jammed about two thirds of the way into the chamber and neither hitting the back of the slide nor pulling the slide open would budge that cartridge from the chamber. The instructor asked me to put the gun down and he removed it from the range. When he came back he showed me that the cartridge was out of spec, since we had three other 9mm’s with us he showed me that the cartridge would not drop into any of the chambers. We hand drop the rest of the box into my Glock chamber and they all fit, I’ve shot quite a bit of the 9mm Fiocchi and have never had a problem with it. What I took away from this is a jamb at the range is one thing, but if you ever have to use your gun in self defense it quite another. So now I take all my EDC ammo and make sure it drops into the chamber of the gun I’m carrying prior to loading it into its magazines. Any suggestions or comments are welcomed.

My daughter owned a Glock G42 .380 and couldn’t get through a magazine without it stovepiping or a failure to feed. Her husband or I never had a problem with it, it worked flawlessly for us. She moved on to an Sig 365 in 9mm and she can shoot the heck out of that gun. We’re all built differently, the Glock just never fit her hand right.
 
Stuff happens... When with the NYPD Firearms and Tactics Section (conducted the dept's firearms instructor school, heavy weapons training and research and testing) we found many (many) defective factory ctgs. All manufacturers, all calibers.

I don't claim any expertise about Glocks or about the mechanics of guns in general. What got me to first look at a Glock was a video by Hickock45 where he said that the only brand of gun that he would trust his life to, brand new and right out of the box, was Glock because of its outstanding reliability. I own two Glocks and while I have not fired thousands of rounds through them I have fired several hundred of different types, brands, etc. and have never had a single failure of any kind. That is why my primary home defense gun is a Glock 17 and my primary EDC is now a Glock 26.

I tend to think that limpwristing is an over used excuse. Of course, I believe in the 1911A1 which depends on its weight when your injured wrist can still get the thumb and a finger around it. Squeeze and it fires and chambers.
