I have been meaning to borrow this and take pics of it for ages. It belongs to a buddy who is president of my IDPA club. It happened in 2003 and was due to a squib not being detected during a frenzied course of fire. Glock 22 in .40 S&W cal ... and you'll see this is a KKM barrel - which he had bought so as to use his lead bullet reloads. No crit' of the barrel - nothing would have handled this I expect.

It was assumed to be just an FTF or similar and - with a rapid slide rack, another round was loaded and fired!! The two bullets had an argument and pressures became, shall we say - excessive!! The mag was forcibly ejected from the grip - but the slide stayed put!! It had to be cut off tho to get at this barrel. The frame is intact and Bill's hand suffered very little - quite remarkable.... in fact no injuries to him or those nearby - just an addition to the laundry inventory!

I had not seen quite such a burst and so thought it well useful to get pics and show them, at last.

Wouldn't this be a KKM kaboom?


Besides - he really needs to clean that barrel out - bit too heavy on the residue there. That should help the problem! ;)

What's the difference between a "KKM" barrel and a standard Glock barrel?

[Rockstar]

Now that's a genuine KB!

[P95Carry]

DMallind ... technically yeah - I guess. But it was used inside Glock so - thus the title.

It is not of course anything unflattering to the gun itself, original barrel or after market - the gun held together remarkably and so this is in no way a crit' of either the gun or the barrel. Both are excellent - under ''normal'' conditions :)

HTG ... the Glock barrel is the polygonal - not recommended for lead. The KKM is std rifling.

Edit to add - I quite forgot in first post to say - this barrel looks pretty darned mucky - but it has since the incident been floating around the guy's gun room .... and so has gathered crud and some corrosion!!

KKM is an aftermarket barrel?

[dmallind]

yep it is

Great pics, thanks. The force required to do that is impressive, isn't it?

Thats gonna leave a mark..........................

[Coronach]

Holy crapola. :what:

Well, you cannot diss Glock or KKM on this one. Wow. That musta been a real eye-opener.

Mike :what:

[George Hill]

Can't really diss either Glock or KKM on this one.
ANY gun would KB with squib and then fire another one after it.

[P95Carry]

Let me reiterate so as no one thinks bad of either barrel or gun - this is most certainly a catastrophic failure, which is nothing to do with the component's being faulty.

For sure - this sorta over-pressure is gonna blow up most gun/barrel combo's.!!

[357SIG]

Well, almost any gun would kB! with a round following a squib, with the exception being the HK USP, which was tested in this manner. :neener:

In all seriousness, Even beefed-up pistols such as the USP are subject to this type of failure from time-to-time. The only thing that could prevent a situation like this is to pay attention to the rounds when shooting.

It is not of course anything unflattering to the gun itself, [QUOTE]

The article may not be unflattering to the gun but the title sure is. It leads one to believe that this is another in a series of Glock "incidents" wherein the design of the gun is suspect in many people's minds. But when you get into the actual incident it was actually a problem that has happened to just about every other gun or gun design one time or another. If it was just about any other pistol it would not be a big issue. But the term "Glock Kaboom" relates to a phenomena which, real or not real, has a meaning all it's own.

BTW, I am dealing with Federal Cartridge right now over a casehead separation which just occured. In my Glock 23. "Glock Kaboom" or cartridge failure is yet to be determined. When it is, I will be relating the findings in a thread i had already started over in the Gunsmithing section.
