I know it wasn't his loads, because he always chrono's just above minor.
Hmmm! I am wondering if Glock has changed metallurgy in recent years?

The metal could be getting brittle from work hardening because of firing pressure hammering on the breech face and then reverse impact causes the failure.

I will have to research this and see if there are more reported instances and causes documented anywhere.

Maybe Ray from GlockWorx might have an answer to this?
