There is more than a little misinformation posted. Here are pictures of three variations of Glock barrels. Note, the Gen 1 was the worst of the three barrels as far as support is concerned. The Gen 3 and Gen 4 barrels are fully supported or as supported as any of my other guns.
I don't know what caused the case failure exhibited here. If there was no noticeable sound in the discharge then you can almost rule out a double charge though it is not uncommon in a 45acp or at least more easily to go unnoticed. Given the excitement caused by the gun coming apart the noise level increase might easily go unnoticed.
The only other explanation would be an out of battery discharge which is more likely the case given the condition of the case. I had a double charge in a 45acp case years ago and the case let go just above the case webbing but was not near as ruptured towards the case mouth. That was in a 1911. Grips cracked, four bullets in the mag burned off but did not fire in the normal sense of the word and all I got out of it was a blackened hand, a bent ego, and a lesson learned. The noise level was louder but not near twice as loud...just louder. The gun barrel was fine and that was with 10.2 gr of 231, assuming it was a full double charge.
Personally I would rule out a double charge but would not be surprised either if a lab tested the metalurgy and concluded it was. I and we just don;t know.
The case in the picture appears to have ruptured from the webbing to well up the case which would lead me to believe it occurred as a result of firing out of battery. I have no idea what caused that to happen. It could be the striker let go when the father put pressure on the trigger ahead of the slide closing, that might do it. The Glock design is pretty simple with few parts so one can imagine something letting go. Who knows?
Beavermeat - someone has told you something on the lines of detonation where gun where a couple of grains of pistol powder all of a sudden becomes a hand grenade or nuclear bomb due to "detonation". Smokeless powder burns it does not detonate. If you do some research you will find that industry labs have never been able to replicate this "detonation" event. Folks in the Cast Bullet Forum whom I have a great deal of respect for have concluded and confirm the same observation. My take on it is simply there just is not enough energy in a couple of grains of powder to destroy a modern firearm. Double the charge though and you are talking a whole different story.
