Our Assessment: The Colt Python was first introduced in 1955, the same year as Smith & Wesson’s M29 .44 Magnum. The now discontinued Python targeted the premium revolver market, and some firearm collectors and writers such as Jeff Cooper and Ian V. Hogg have described the Python as the finest production revolver ever made. We tend to agree, and this is a great example. It is in Fine condition with 94% of its nickel finish, a great bore and strong mechanics. The 4″ barrel is a nice balance between being compact enough for carry but with a long enough sight picture for precision. This should make a great shooter for the lucky winner, and with its nickel finish it would be great for the collector, as well. Please see our photos and good luck!
