My buddy just had his longside Glock .40 (not a Glock guy myself-don't know the model) turn itself into shrapnel in is hand. I don't think that the usual kB story is the reason. The barrel hood peeled back, the slide deformed, the frame cracked, and just about every little piece of the gun made itself scarce. To me this doesn't sound like a problem from a under-supported barrel but more like it fired out of battery. He thinks Glock or CCI (he was using factory ammo) is to blame. I'm thinking it's the kitchen table trigger job. Any thoughts...

My guess would be a double powder charge (at the the CCI ammo factory) with that particular round fired. It takes quite a bit to peel back the chamber hood on a barrel. I would contact both CCI and Glock and explain what happened.
 
CCI Blazer by any chance?

No pictures means this whole incident could be based in fantasy and not reality too.

I had thought about that :) With digital cameras for cheap, and available in cell phones, I'd like to see pics.

That could be too, trying to make the gun 'better'.
 
.

Was there a small diamond lodged in the barrel at the time of this
alleged Kb ? That is a common cause.

:confused: :uhoh:
 
I ALWAYS stay away from CCI Blazers. A friend of mine who had a XD, kept having problems with the CCI.

Tell your buddy to notify Glock, they'll give him a new one since he used factory rather than remanufactured/reload ammo. Glock warranty is still good. Make sure he takes pictures of it for liability or proof.
 
Hmmm.. this makes kaboom number 987,465,475 for .40 S&W and all the other calibers of glocks combined have 498 kabooms.

My calculations are absolutely correct.
 
gudel, I don't take my camera everywhere, and refuse to have a cell phone camera, so does that mean anything I say is based in fantasy, too? This isn't his gun, so if he can't take pictures, that's not his fault.
jman74, having said that, if it's possible, please post some pics of this, we would like to see it. Hope his hand/etc is OK. If he did a home gunsmith job on his trigger, which factory is too light anyway, then all warranties would be null and void. Always a good idea to have a certified professional do any work on your gun, with any and all guarentees.
 
If the gun is really blown to smitherines than they wouldn't be able to tell if you bubba'ed the trigger. Ask them for a replacement, Glock ain't goin broke if they have to give your buddy a new gun.
 
I will get pictures when the barrel and slide come back from being x-rayed by a metalergist. No I wasn't there for the actual event but i did examine the zip-lok bag full of pieces. I don't generally carry a camera to work with me and didn't know that he was going to show up with a baggie filled with what used to be a firearm. Maybe the people who are thinking that I'm saying that this is the mysterious Glock kB should reread my post with both eyes open. I'm saying that it DOESN'T seem to be that at all. It looks like a type of failure that could happen if a gun fires out of battery and/or is firing overcharged ammo. Or quite possibly fired with a squib lodged in the barrel. Sorry to those of you out there too sensitive about your favorite firearm to objectively reply. I didn't mean to touch a nerve. I've got nothing against Glock other than they are not single action. As close as I can come to to liking anything other than SA is the XD trigger, but I'll take any of my 1911's or BHP's anytime.
Both Glock and CCI have deicded that it was the other guy's fault.

a disproportionate number of Glocks are chambered for .40 now the 357 Sigs and .45s are starting to surface also. The 9mm Glocks seem to be fairly safe with only a very few KBs and there are a large number of the old Glocks in 9mm.
 
Lots of people shoot Blazer without problems. Sounds like a double charge, it happens.
 
I blew up my 21 several years ago...Glock fixed the gun but I never like the gun much after that. Now I have a 9mm in the collection & it just shoots & shoots & shoots ;) Their 9 mil's rock! :cool:
 
...if it were strictly from firing a little out of battery, I would think only the case web would blow out, not the entire barrel.

Absolutely correct... it sounds much more like an overcharge or undercharge leading to detonation.

An obstructed barrel will rarely cause such a rupture either... the FBI purposely lodged a bullet in the barrel, 1" ahead of the chamber, of a .40 Glock during their Field Suitability Evaluation and fired one round of service ammo without rupturing the barrel, slide or frame.

FWIW
 
An obstruction would usually cause the barrel to bulge at that point, and if it ruptures it would do so just behind the obstruction. Out of battery should cause a case failure which should vent downward, blowing out the mag, maybe the trigger parts, etc., but I don;t see how that would cause a total destruction.

Seems the only situation would be an overcharge or detonation. From what I have observed it seems the factories tend to use faster burning powders. That allows them to use less grains per case, which is cheaper if you are paying for powder by the pound.

Fewer grains of powder per case generally means less volume. Less volume per charge makes it easier to double carge, or for the charge to get into a postion that it can detonate. The ideal for safety would be to have a type of powder that completely fills the case, or nearly so. This would make it impossible for the powder to shift around and prevent double-charges. Which is what we reloaders often try to do. But then reloading is BAD! :evil:

I don't know why the gun is getting X-rayed, but the guy needs to call Glock or have his Dealer call Glock and explain the situation and make sure they understand he was using factory ammunition. Glock will ask for the pistol so they can examine it. Make sure they pay the shipping! Your friend needs to stand firm that he expects a new pistol from Glock. He will likely get it.

Theres another thread over on arfcom going right now about a KB'd Glock fotay'. Are other caliber Glocks known for this, or is it pretty much just the .40's?
 
From what I've read, kabooms are almost exclusively .40s

If the entire mailbox on the barrel is split open, this is not a kaboom. The famous kaboom is caused when the case ruptures near the head, and vents into the magazine. The rupture usually destroys the magazine, maybe some trigger components, and possibly cracks the frame.

In this case, the barrel failed, and that is very unusual.
 
I think some Glock, and other .40 caliber handguns, have gone kaboom and people just don't want to let it die.
I have never cared for the .40 caliber and like the caliber even less after owning a couple of pistols so chambered but I never blew one up either.
I did blow up a 10mm EAA Witness but that was completely my fault and no bad against the manufacturer whatsoever.
The .40 boom boom saga definitely gets people, myself included, to posting.
 
I thought most of the Glock Kabooms were in 45cal.

I'm not sure what caliber this one is.
