Well - always interesting to see what happens with KB's. I posted these on THR some while back but thought folks here might appreciate seeing what can happen!!! I am gonna cheat and paste the original as it is -

Note - this is NOT a Glock failure!! (per se)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

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.

He was lucky Bud - more of a hand ''stinging'' than any real damage.... but you'd think otherwise!!

Great Photos P95

How do you spell VIOLENT INTERNAL EXPLOSION?
Amazing.
Thanks for posting the photos.

Randy - I think Bill may well have expedited a change of laundry - tho I wasn't there. Just borrowed his barrel to take pics. Which incidentally is why it looks a tad dirty and tacky - it has been a demo item all this time!!

QK - "VIOLENT INTERNAL EXPLOSION?" Ahh well - that is spelled ...

"VILENT INFERNAL SPLOSHUN" - thought you'd like to know! :biggrin:

Jeez. I love my Glock 22. I've had no trouble with it at all. Yet, I'm getting really nervous these days. I bought it before I was aware of the Kaboom factor. So far, the only kaboom stories I've heard with them involve reloads, lead ammo, or stuff like what Chris just posted. Still, as I said, I'm nervous. I've gone so far as to discard any ammo I've cycled once, say for a cleaning. If I eject a round prior to disassembly, or for "show and tell" with new shooters, that round doesn't go back in the gun. It goes into the "when I have another .40" pile. I don't want to risk any degree of bullet setback.
But, darnit! I'm emotionally attached. :grumpy:

I actually had that happen to me...same scenario...reloads...squib....

Barrel wasnt quite as bad...although it was jammed into the slide. It does sting...and feels like your being shocked too...highly violent act to have occur in your hand. I got a small 1/2 in burn on the top of my trigger finger....and a pc of metal from the extractor hit me in the upper lip and started to bleed.

The gun shot the mag out, and the trigger...cracked the frame from mag release to trigger opening. blew the extractor out as well. That was my 1st experience reloading.and it was my last as well...(dont even try to talk me out of it)

OUCH!!! :eek:

What was being fired? I hope it wasn't a stock .40 S&W.

5K plus through my G23 and never a hint of a problem. These KBs tend to all be squibs or bad reloads. This kind of thing can happen in any gun. You hear more about Glocks becuase there are so many out there.

BTW – I bought a Glock 40 barrel last year for my G32. It is more supported than the barrel for my G23 that I bought several years back. It seems Glock has tightened them up some.

RSSZ - I am an engineer but not in the firearms field. However - the main deal in these instances is covered by the word ''containment''. Just checked and the .40 round is generally about 22,000 CUP, not overly high when 9mm is up over 30,000 - but when considering a normal firing, the pressure has an early peak probably around or just before rifling engagement. After that the pressure falls off as bullet passes on.

In this type of situation the normal spike has probably barely passed when further reduction in pressure is prevented due to obstruction. Then I imagine things get interesting because this pressure has nowhere to go and so probably rebuilds to a new peak level, many times normal. In PSI terms I imagine we may be seeing something in order of 100,000 perhaps. So something has to give! It is a small bomb!

Gee

I wonder what a stuck squib followed up by an accidental double charged cartridge would do???
Be Careful You Sloppy Hand Loaders (wherever you are)! :wink:

QK - all relative. Difference between Kaboom - and KABOOOM ... :biggrin:

Maybe too a shade more hand damage (ouch!)

Typical 40. Funny, a Colt 1911 in 45ACP won't do that. The reason is pressure. High in 40 and low in 45ACP.

First destroyed 40 I ever saw--1991--was caused by a squip in the barrel. Looked the same, except a Glock barrel.

Ive solved it the easy way stay away from the 40 and dont worry about it funny the 40 seems to kaboom more than anything else

P95...

a bunch of guys who enjoy shooting and stuff were discussing these pics yesterday at work (we're all engineers.) A quick mental calculation based on pressures usually seen in the .40 cartridge and then the factors of safety built into barrels, done by a co-worker put the pressure somewhere in the 150,000 psi range, but that was just a guess...

firefighter - well I didn't try any math - just stabbed at a guess but yeah - thinking of FOS matters, wall thickness etc - your figure is well possible. As I said - pretty much a small bomb! :eek:
