Gentlemen, glad to be back shooting and on this great forum again, after a period of health issues. Dr's. wants me to start out with a light caliber, as in 22lr. So, I have been looking on the internet for a Colt revolver in 22lr. I have come across Colt Frontier, Colt New Frontier and Colt Frontier Scout. Could some one please give me a simple description of the differences, as most articles I read have a slightly different description from article to article. Thanks for any information you can send my way.
