One of my good friends and I plan on getting our CCWs once we turn 21. In CO, as I am sure you know, you know to show proof that you have completed and appropriate course in handgun training. Does anyone have any recommendations for specific courses/instructors? These can be basic CCW classes or more specialized self-defense classes, it doesn't matter. We would both like to take self-defense classes at some point, so maybe that would be a plus. Anything is appreciated.
