Glock kaboom

[Bondslave]

Has this particular malfunction only been reported on the .40 caliber glocks or on all of them? Also, does the kaboom result in serious injury? Sorry if this has been discussed but I'm new, and I did try the search function.

Indeed, this problem has been reported in ever major pistol by every major manufacture when using defective or improperly loaded ammunition.

One of the best sources of information for Glock kabooms is Dean Speir's website www.thegunzone.com

That being said, things to avoid with Glocks are handloaded ammo, +P ammo and lead bullets.

Thanks for the link Brick that was very helpful.

MarcS: So are you saying I shouldn't let the kaboom factor in my decision between a glock 9mm or .40?

It shouldn't be a factor.

First, they're so rare as to be nonexistent. Millions on millions on millions of rounds are fired safely through Glocks every year, and have been for the past 21 in the U.S. Second, they happen with every gun ever made -- Glocks just get noticed more because they were the first super popular polymer frame guns. Third, it's a reload issue. Don't reload, or reload responsibly, and it won't happen, regardless of caliber.

Thanks for the help guys, very useful info.

The reason no one wants to mention is because the glock .40 does not have a fully supported chamber....that and the reloads could cause a KB with that combonation....c'mon people don't hide the truth...

Truth is, all Glocks are made with a chamber that doesn't fully support the case head. Not just the .40. So any weakness of the cartridge case near the head can cause problems. This is also part of the reason some guys won't use cases fired in Glocks for reloading, since resizing won't always iron that little bulge out. Glock's polygonal rifling is the reason why lead bullets aren't recommended. Without the grooves, there's no where for the foulling to go.

But, all in all, the Glock is a good pistol. Stay within the pistol's limits and you'll likely have no problem. But that's a rule that applies to all guns.

What I like most about the Glock is their simplicity of operation. Load them, chamber a round and squeeze the trigger, that's it. Just remember that any pull on the trigger will cause a chambered round to fire. So keep your finger and any jacket drawstrings or shirttails or anything else out of the trigger-guard when holstering the weapon and you won't get a surprise.

Have fun and stay safe.

No need to avoid +P ammo. I shoot them by the hundreds. Last time FultonCountyShooter and I were at the range I was shooting Remington +P+ ammo.


The Glock .40 has the highest reported KB rate, but it is also the most used Glock in Law Enforcement. More numbers = more KB's.

The higher pressure rounds ( .40 10mm 357 sig) have higher reported cases of KB"s than the .45 or 9mm. Very few reported cases with the 9mm.

Bad factory rounds, lead bullets and reloads have all been known to blow up a Glock or two. It's not hard to find KB's from other brands on the net. Just remember, LEO's MUST report a KB of their duty weapon. Civilians dont have to...and many times don't if their reloads were at fault. I'd love to know how many other guns KB...but that info is hard to find. I did see pics of the new S&W M&P Kaboom already. You guessed it....bad reloads.

I had a Kaboom in a 17. It was ammo related (reloads).
That's the only Kaboom I've heard of with a 9 mm other then guys using lead bullets.
