I've seen a 1911 blow. It was a 10MM with a standard feed ramp. The case ruptured, blew the magazine out of the bottom, split both grips, and sent pieces of brass into the shooter's face. Anything can have failures.
But the frame didn't come apart in the shooters hands either, did it? I once saw a stainless S&W .40 semi-auto let loose from an over pressure round and it acted exactly as described. The magazine jetted out the bottom, the grips split, brass splashed back onto the shooter, but the frame held together and caused no injury to the shooter.
