Something is awry here. For 100 years, people have been using Colt handguns for competition, military, police and personal use. People have run far more than 12,000 rounds through their guns. The inferior metallurgy of the WWII era 1911s had lasted so long over the years, some even made it onto the domestic market to be turned into competition guns.
And yet suddenly, one website claims a Colt can't make it to 12,000 rounds without cracking?
I would imagine the guys who put so many thousands of rounds through their commercial Colts would've been mad as hell by now.
A dust cover crack like the one on that site would never happen with a high quality forged gun in so little rounds.
I'm waiting for more info on this one.
