In Colorado no course of fire required. Carry any handgun you want and as many as you want. I'm big on "shall not" but without military or LEO training I think course fire is good common sense. Frankly I'm uncomfortable around anyone with a firearm who doesn't have military training. Nothing like a Drill Sgt (Drill Instructor for the Marines) explaining it to you. Sorry to say my Drill Sgt seemed to always have his foot in my *** (and everyone else); I seemed to have had a better attention span.
