Our Assessment: Frequently referred to as the “working-man’s Python”, the Trooper MK III was introduced in 1969 after some modifications to make the revolver less expensive to manufacture including the use of sintered parts, which were easier to fit and heat-treat, the use of a coil mainspring, which again didn’t need as much hand-tuning and was cheaper to produce than the v-leaf spring used in the Python, and their new transfer-bar safety system, which prevented the ignition of a round without the trigger being depressed. This put a Colt-quality mid-frame .357 revolver in the price range that the working man could afford as well as being more attractive to law enforcement agencies due to the new safety feature. The Trooper was the premier model in the MK III line with a shrouded ejector, full length rib and heavy barrel. This one is a limited edition made for the Immigration Services 7th Anniversary and has beautiful gold markings on the frame and barrel. It looks like it was added to a collection and stashed away over the decades and is a great addition to a Colt collection with only 300 produced. Please see our photos and good luck!
