At Glocktalk I was reading that some Glocks have blown up because a Glock can fire when slightly out of battery (Slide not totally locked closed). The moderator said he personally witnessed a Glock 21 blow up using factory 45 ammo. Its all news to me. When I go to the range and watch what kind of firearms give problems it never seems to be Glocks. I have never heard of a Glock actually blowing up. I am 55 years old and the only gun I ever heard of this happening to was a revolver that had fired a squib load that lodged a bullet in the barrel then when a non squib was fired after it the barrel was bulged and ruined. Maybe others have heard of these problems?

Heard them? Sure! Are the true? Well, I'll say that I am not a betting man unless I am going to win, and I would bet on a glock not blowing up ever (unless a squb round cause a malfunction.) Now, i do say never, and you should never say never, but I think glock makes the safest gun without malfuncton. That I why I own them.
Cheers,

I would have to say that I really dont believe any of the bs about the glocks blowing up, an if there is truth to it its not the weapon's fault, its the shooters or the junk amo being fed to it. Get a squib load lodged in the barrel and try to put another one behind it and BOOM! That would happen to any gun though. I myself would bet my life on any glock. Ive shot thousands of rounds without a malfunction, it always feeds, always fires and always hits where you aim it. Oh yeah, I have a freind with a kimber custom defense thats a pos but does that make all kimbers junk?? Not hardly !! See where Im goin' here?

:-D General information guys. The probalem originally stemmed fro the model 22 Glocks. What it was,was that the shooters were using reloads in that caliber,and they were blowing out the case in the unsupported area of the case as it sits in the barrel. Not the Glocks fault. ammo related. I have witnesses a squib load in a glock bbl and then a good load fired directly after it. Did the gun blow up...nope...came out of battery and some other rather interesting things,but the gun stayed together. More importantly..the shooter was not injured at all. Dont know to many guns that will hold that and not turn into a grenade stay safe...king

Just so happens I have a G22 and i DO reload for it. 155gr. FPT Rainier 5.7gr. WST pushing right around 1000fps. no signs of over pressure, in fact the case dosent even swell as much as factory loads. Ive heard that the 180gr lead bullets was the major issue with the blow ups.

More information can be found..........

I own three Glocks at the present time, so I am not "anti" anything....however if you are looking for more information on Glock problems, try the site: Glocksucks.com.

O.K. I looked, the title does imply bias.

Right in the site it says test results to determine what's causing this problem are inconclusive.

Why do kB!s occur in these Glock models?
Reports compiled by Speir from various independent laboratories are inconclusive as to one single cause for the catastrophic failures.
Then it goes on to say

There do, however, appear to be several contributing factors which collectively may induce catastrophic case failures:
I added the italics to appears. He says "appear" and doesn't say "does cause"

Here are the factors they point to.

Firing out of battery. Most Glocks will do this to some degree, especially those improperly maintained.

Significantly overpressure rounds. These occur mostly in homemade reloads or in commercially remanufactured ammunition, but have occurred in factory ammunition as well.

Lack of full case support in the critical area over the feed ramp of all large caliber (.40 S&W, 10mm, .45 ACP) Glock pistols.
Ostensibly as a measure to promote feed reliability, Glock chamber mouths are slightly oversized. One can test this by removing the barrel from the Glock, dropping a factory round into the chamber, and observing that there is brass exposed at the six o'clock position. Take a fired case and note that there is a slight engraving if not actual bulge around the case web, which is most pronounced in the area of the case which, upon firing, was in the six-o'clock position

Use of personally reloaded or commercially remanufactured ammunition utilizing cartridge cases of indeterminable generation. Unlike most rifle hand loaders, those who reload for handguns do not as a habit segment their fired cases by generation, and each time a case is re-sized for reloading, the brass "works" and weakens through enbrittlement.

Several kB!s have been documented with factory ammunition, but most of them occur with either commercial or homemade reloads.

They then post this FAQ

Do kB!s occur in other guns or just in Glocks?

kB!s do, of course, occur in other guns, but no one appears to be keeping accurate statistics for most of them. Many 1911-style handguns have partially unsupported case mouths, and numerous case separations have occurred in these guns. Early .38 Super barrels were particularly susceptible, and the critical observer may have noticed the predilection among USPSA .38 Super competitors for full beards in an attempt to cloak the vestiges of what came to be known as "super face."

Respected firearms author Frank James, in 1994, documented a number of kB!s in HK USP .40 pistols, which do have fully supported chambers.

This is not some new phenomenon. We went through this back in the late 60's with Super-Vel in auto's (wow, I'm old, I remember that, oh that's another topic.)

One of the things they don't mention is the problem that was credited with causing the Super-Vel problem, the bullet bullet getting pushed back in the case during loading. Push that bullet back in the case on a high performance load and pressures are going to rise.

The mention not shooting certain Federal 40 S&W ammo. That was pretty well documented as a problem of the round getting pushed back in the case. But they don't report that.

They also mention that Glock does say don't shot Reloads.

The Glock sucks aside reference aside that is a very interesting website, until the end. The whole website and the information presented comes a across as credible, that is until you read the last paragraph.

That last paragraph makes the whole website look like a website of some one with an ax to grind. It's a shame


I would add here that you can sell your plastic fantastic to some unsuspecting moron or some CQB Killer wannabe or a flat footed local Barney Cop and by a real gun, like a SIG-Sauer, Walther or H&K.

GARY LAMBERTH - Your exactly correct and although you have probably far more rounds fired than I thru my Glocks.

I know two guys personally that have had trouble with their Glocks, BUT they replaced factory parts... one guy thinks (his first Glock) that he has to replace everything to get his guns to shoot better. The other guy double charged a case and the result was a KB.

I personally after all these years of owning Glocks have never had a problem and all of them are stock Glocks.

I own a G26 now and I have to admit that it is the most reliable gun I've ever shot out of the box. I've done nothing to this gun but shoot it and carry it.
While some may say the 9mm is a weak round that just pisses people off, I sure would not want to be on the muzzle end catching those "weak rounds".

The G26 I have is a very nice pistol that I seem to carry a lot. It's small, lightweight and I KNOW that it will function when I pull that trigger. So what if it is a 9mm? that doesn't matter. What matters is that I trust that gun to function, and that is more important than caliber.
All I can say is so far, so good.
I personally would not buy a Glock for 40S&W. That is why I have a SA XD40. I am a little worried about Glocks "blowing up" but only in the 40S&W caliber. It is a high pressure round, and the problems seem to be coming from the fact the barrel has a cut on the bottom side of the chamber that causes the casing to be less supported than say... a SA XD40's chamber..
.357 Sig in a Glock?? NOT FOR ME. But Glock has their stuff together when it comes to the 9mm. The one I own is the best 9mm I have ever owned or shot. And I have had many 9mm's over time. It's just a matter of personal preference I believe.
