I ran into a LEO I have known for several years. He always had a holstered Kimber 1911 on his hip and shot it VERY well. Today he was wearing a Glock something. He is the Chief of a local police department. When I commented on his different side arm he told me that the cops in his department would not maintain their Kimbers so they had been forced to switch to what he called "combat tuperware".
I am not commenting on one vs. the other just posting this for a topic of general interest.
