I can't tell you much about Glock 10mms; but the only Glock that totally disassembled itself in my circle of friends was a brand new G20, in 1991 or 1992. First shot from a new gun. The cartridge was a reload, one of many cranked out by cops who shot pusedo-IPSC at a local gun club. The ammo was immediately blamed until we loaded two mags directly from the box that wrecked the G20 and fired them from a Colt Delta- without incident.
This problem was a lot more prevalent in 40 caliber Glocks, until Glock quietly increased chamber support.
