Took a recent trip to Colorado for vacation. Decided to fly and my wife suggested taking a pistol. Wasn't sure how it was going to turn out but I read all the rules I could find and thought why not? Check in was easy, told them I wanted to declare a firearm. The lady smiled and asked if it was unloaded and if it was in a hard case that was locked. Signed a form and placed the form on top of the pistol case and that was it. Basically the same process in Denver except they took an x-ray of the suitcase. What a country.
