Glock pistols have a reputation for being indestructible.
These Glocks obviously never got that memo. These fails might give you nightmares.
Glock handguns are like any other weapon that tries to harness the power of an explosion, and they can be prone to damage on occasion. If firing only lead ammunition through a Glock factory barrel, the polygonal rifling can get clogged and increase pressures to dangerous levels. Reloaded ammunition might be badly overloaded.
It is unclear whether this is a factory original barrel or an aftermarket one.
This unlucky Glock shooter had a catastrophic kaboom that destroyed his pistol and his hand.
Not much information is available about this incident, but my guess would be a reloaded cartridge with a possible double charge. Carelessness can really hurt…
Was it the ammunition or the barrel? With not much information to go on, I would again speculate badly reloaded ammunition.
That is a lot of power exiting that pistol in the wrong direction.
