I never saw anything like this for a Colt 1911
Any firearm can have a catastrophic failure if you dont treat her right.
Colt 1911s are famous for leaving a portion of the case unsupported, and yes there have been a number of kabooms related to this issue.

I over loaded a reload in a 1911. It was a commander size Kimber. The result was the magazine blew out the bottom. The only damage was the magazine catch, the plastic floor plate, and my pride.
