When Louisville Metro switched over to the Glock 22, they bought them from a local police supply place/Glock distributor, who also was a Fiocchi ammo distributor, and he sold a helluva lot of that ammo. I know several folks who bought the Glocks and a bunch of Fiocchi ammo to use "because that's what the cops used" and it was very remarkable that nearly to a man they had a lot of Kabooms. That was traced to the Fiocchi ammo which had thin case heads (Louisville Metro carried Federal ammo, so they didn't experience those Kabooms!) that the everyday shooter was having.
I have no idea if Fiocchi has fixed their ammo or not, I haven't ever bought any of their centerfire stuff (and most of the rimfire stuff sold here is contracted out to CCI, except their fancier match stuff).
But YES, Glock 22s have Kaboomed a LOT, at least here in the Kentucky/Indiana area, I've seen it happen with my own eyes.
