To try to characterize it as a GLOCK problem, as though they're the only guns that have catastrophic failures, is pretty ignorant.
I'd like to know what is diagnosed to have been the cause of this one.
I have a GLOCK 22 -- but I don't worry that this is something intrinsic to the GLOCK or to this model. They say don't shoot lead bullets, and don't shoot reloads, and so I don't. Where's the problem? Is someone gonna say that I should be expecting this to happen to my gun?
