I have put over 5,000 rounds through my Glock G-29 10mm, mostly jacketed reloads. Some of our loads have had enough pressure to rock the foundations of hell itself, and never a glitch from that little gun.
I don't think it is a failure of the Glock design, on that aforementioned little G-30, but rather something that was wrong with *that particular gun*.
If there was an inherent weakness in the Glock design, one would think it would have shown up in the 10's first.
