"No doubt bad ammo - so Glock likely will not replace it."
My buddy blew up his G27 with his reloads, and Glock DID replace it. He even called them to see if they could fix it and got the shop crew on the phone "Hey guys, it's Mr Abcd! Mr Abcd, are you OK?" And a new gun came to him with (he swears) the same serial number. Of course, this was back when Glock was getting a bad reputation for KBooms in .40 S&W pistols so maybe they were trying to improve PR.
