I have spent a good bit of time both at Colt Defense and Fabrique nationale.
Both are excellent companies. FN though, is a thoroughly modern, completely state of the art factory that I was immensely impressed with its capabilities.
COLT, is a great manufacturer, and its weapons are top notch, but the facility leaves a lot to be desired. The unions are destroying colt.
In the end you cannot go wrong buying either and I would carry either into battle with confidence.
