Why is a 1911 not safe to carry with one in the chamber? The only proper manner in which to carry one is loaded chamber, hammer back, thumb safety up. From a purely mechanical analysis, there isn't a design safer than the 1911. I carried one that way, on duty and off, for years.
Very few handguns are not safe to carry with a loaded chamber, and I would not have one I could not carry that way. An empty chamber is dangerous in at least two ways: 1) it is not ready to use when you need it, and 2) you will be futzing about with the pistol trying to get the chamber loaded when you need it, which is a better way to generate an ND.
