Title: Blown up Glock
Post by: jc2721 on July 26, 2015, 01:56:36 PM
I heard from one of the RO's at the pistol range today that someone blew up a .40 Glock this morning.  Apparently it was a double charged reload that split the barrel open--a "banana split" was how the RO put it.  I guess no one got hurt.  Anyone witness the "event" today?

Today a gun owner severely damaged his Glock pistol while firing a cartridge containing double the maximum recommended amount of gunpowder!

In other news, gravity is believed to have caused a three-year-old toddler to fall down at the playground.

 :crazy:

Sometimes "Well, Duh!!" just doesn't capture the moment!

I don't reload .40 cal so I cannot speak to it being a double charge. But with 9mm you can't double charge the case without powder overflowing the case. I suspect the same may be true for .40 cal. Maybe someone who loads .40 cal can verify this for me.

Yeah I'm thinking the same thing about the load.............possibly a full power on top of a squib?  I just can't see the overcharge splitting a barrel.

Exactly why I asked the question. My guess is that they either used the wrong charge, not a double charge which would have spilled over and would have been obvious. Or more likely to my thinking is that they used the wrong powder. Or maybe even a combination of both?

Guess the first question to be answered is "was it a "bad" reload" ?   >:D
If not, most likely a squib.  :shake:
And if that was the case, I would've hoped someone to the right, left or middle would have called it CF.  :sleeping:

Possible and easy to double charge a 40 case.  Did it myself and fortunately caught myself doing it.  I'm sure it happens all the time.

Depends on what powder.  You could double charge a .40 case.

how come the brass looks better than the barrel?

I think it looks funny that the barrel split so perfectly longitudinally. I have never seen a barrel split like that before.

Apparently the word on the street is if you want to shoot reloads in your 40, 45 and 10mm Glocks you should replace the stock barrel.

==============
For what it's worth, here are 2 pictures of KKM kabooms.
One pic was at KHSC almost exactly 2 years ago.
The other pic is the current topic bbl.

it's almost as if they were designed to fail that way

is the frame and slide damaged as well?

=============
As I recall, the kaboom 2 years ago was almost certainly a bullet stuck in the bbl. The picture seems to support that conclusion.
In this new kaboom there is a bright spot in the bore at about the same location, but I don't see any bulge.
So I'm not even going to try to make any sort of guess.

I think that is an Aftermarket barrel, am I right?

Yeah that struck me as odd too.  From the KKM site:

Quote
All KKM barrels are made using certified 416R gun-barrel quality stainless steel bar stock. These barrels are then heat treated and vacuum tempered to 45 RC. All of our barrels are CNC machined to obtain superior dimensional tolerances over stock. Because of our advanced proprietary button rifling process, all KKM barrels offer greater accuracy over stock barrels. Our Glock barrels come with fully supported SAAMI spec. match chambers for shooting factory or reloaded ammunition.


Hypothetically speaking I'm wondering if it's a combo hot load and a manufacturing mistake such as with heat treatment.



Teichi - thank you for posting pics.

It just stuns me to think that anyone would design a barrel to fail in that manner.  I don't understand how the barrel would split horizontally like that.

Also I was shooting a couple of weeks back and a guy had an issue with his pistol.  Turned out to be a live round on top of a squib.  The barrel in that case (HK) bulged and locked up the slide but there was no other signs of failure such as bulged slide, expanded (polymer) frame or anything else I could see.

HKs are actually tested with a squib load when they are torture testing

I have confidence that the large manufacturers/barrel suppliers would test and QC test their products.  I wonder how many of these aftermarket guys continue QC testing their products.
