    Blame notwithstanding, a disinterested manufacturer does not enhance my confidence.

    I do not believe carry ammo around causes any effect on the powder.
    Another thing is that an under charge is more dangerous than an overcharge, and I bet this is what happened.
    Bullet may have not been pushed out fast enough to keep back pressure from building up. Or, round got stuck and second round did the trick.

    Glad you're OK other than having to buy new underwear and a new weapon!

    Looking at the photos, isn't doesn't look like a squibb load as there is no buldge in the barrel, but from the chamber splits on the barrel I'm thinking maybe the bullet was seated to deep or push back down into the shell brass reducing the shell volume and over pressurizing the round?

    Again glad you're OK and keep wearing your safety gear.

    Good reminder to wear saftey galsses and ear protection.
    Glad it didn't turn out any worse.

    That makes much more sense than too much Shake 'n Bake on the ammo. I have never had a squib, or even seen one, but would there not be a noticeable lack of report and recoil from the faulty round?

    Doesn't bother me a bit that Glock didn't want to see it. They wouldn't learn anything from it and examining it costs time and money. They have tested their guns 4 ways from sunday under controlled conditions and that includes blowing some up. They can tell from looking at the pictures it wasn't their guns fault. The big clue is the chamber of the barrel ripping open due to over pressure. When they see that they know what the story is. They know within a few percent how much pressure it takes to do that.

    The OP is right, this was an ammo problem. Probably a significant over charge of powder but I'd doubt it was a full double charge. I don't see any reason that riding around in a motor cycle saddle bag would do anything to screw up the powder enough to make it do that. Besides, the other cartridges had been riding in the same place and they didn't blow up.

    That is what I call a Kaboom! I am glad you are OK.

    I am skeptical about your theory.

    I was thinking exactly the same thing.

    An under charge in a pistol is only dangerous if it causes a bullet to stick in the bore. Different story in a rifle with the longer barrel, but in a pistol, if the bullet gets out the muzzle, there is no problem. The gun may not cycle, could jam, etc. but it won't blow up unless the bullet gets stuck in the bore, and then it will be the next round that does it, not the undercharged round.

    In this case, given that the gun felt the same for the preceeding round, I doubt it was an undercharged round that stuck the bullet. If it did stick the bullet, it would more than likely still be there stuck in the barrel with the second bullet behind it.

    The bullet not being pushed out fast enough to keep the pressure from building up makes no sense at all in a short barrel. if the pressure is there to blow the gun up, it will push the bullet out ahead of it. In a rifle different story - the bullet can lag due to an undercharge or incomplete burning and simultaneous late combustion of the unburned powder in the bore can cause a big pressure pulse - this has been measured but seldom results in visible damage. Not going to happen in a pistol - barrel is too short.

    I don't know whether they looked at the picture or not. Aside from the picture, it is all speculation, anyway. One person thinks maybe the powder got bounced around too much, another suspects a squib load, a couple others think overcharge. The ammo manufacturer assures the reliability of its product, yet buys the user a new firearm in exchange for his discretion in not mentioning them by name. All I know for certain is there is a picture of a pistol-turned-fragmentation-device of a very similar make to the ones I carry and rely on. I know they blow up from time to time, but believe having some idea of particulars might prevent similar mishaps in the future.

    In most cases I would agree that just carrying ammo around would not cause any effect on powder, but this ammo was carried in the saddlebags of a Harley on a cross country trip covering over 14,000 miles. That's a lot of vibration
    I am certain that there was no bullet stuck in the barrel, as I saw the impact of each prevous round in the target. As far as an undercharge, I doubt that also, as the felt recoil of each prevous round felt normal, and each round struck the target near point of aim.
    I don't claim certain knowledge that the a breakdown of the powder caused the problem, but I believe it is a real possibility.

    Glad you got back up on that horse so quickly! I think I would have needed to be retrained all over again after a substantial break. And, of course, glad you were not more seriously injured.

    What put you on the powder theory? I have looked around, and have not found powder breakdown shown as a cause of catastrophic failure anywhere. Was your Glock not covered under warranty?
