Being a retired LEO, I have CC'd for about twenty five years. Ret cops can CC in all 50 states if they qualify with the gun in their home state. Since I just moved to Co. from Ga. I will have to qualify here, and I will for travel purposes. Co. is an open carry state but believe me it isn't welcomed and is actively discouraged. My first day OC'ing an old timer asked me the same question "is that a real gun"? Glad I didn't respond hastily because he was a WWII vet and admired my 1911, he too didn't know OC was legal. Lots of Subaru's bike lanes etc here, I may be a little to southern for Colorado, the juries out!
