Solution: don't use Wolf ammo any more (it's Russian-made using laminated steel case instead of brass). I got it as cheap practice ammo, but it's not worth the risk
I've seen similar problems with the mini-Glocks using aluminum-cased *Blazer* ammo from CCI, cheap for inexpensive practice and a neat technological step forward, but far from perfected, it seems. I have had six Glocks since they were introduced, and am now down to two; they've been very reliable and servicable for me, and I have no complaints, but I've gone back to the original full-size Glock 17 9mm and a mini-Glock 30 in .45 for concealment use.
I'd be very interested in knowing what tmodel of Glock you observed your difficulties with, and any more details you might share about your pal's Glock blowup, being known more and more commonly by the less precise term *Glock kaBOOM.* But it's also worth noting that military-issue M1911A1 had difficulties with WWII issue steel-cased ammo too, often found with the headstamp *EC43* from the E/vansville C/hrysler plant where it was produced by the millions. Various stoppages and extractor breakage have been reported, as has ejector battering and ejector pin shearings, though the ammo reportedly functions fine in .45 Thompson and M3/M3A1 submachineguns, in which its use was really intended.
But my dad carried it in his Air Corps-issue .45 with which he guarded Norden Bombsights and classified target analysis documents, and my paternal grandada carried the stuff in the Reising submachinegun with which he guarded a critical railway bridge when there were well-deserved concerns about enemy saboteurs landed by submarine. So the stuff was around then, and sometimes still shows up as closeouts of leftover wartime stocks, nearly 60 years after the fact.
The lesson is clear: a good handgun deserves good ammo. And Glocks are also known to be very intolerant of imprecicely reloaded fodder, so stick with high quality factory ammunition.

Mine is a glock 30 in .45 cal
The glock that blew up was a glock 19. Don't know further details, was told this by the gun-store owner who I had help me get the case out of the gun. In all three events, the cause was a case rupture. The case that caused my problem had a crack from the case mouth down 2/3rds of the case. I think I'm fortunate that it didn't crack all the way down, spewing hot gas into my almost-full mag
