Our Assessment: Inspired by their success with the Python, Colt released the Diamondback in 1966 in .22 LR, .22 WMR and .38 Special calibers. It was designed as a deluxe model and has a serrated wide target hammer, ventilated rib, target quality sights and a full length barrel underlug. If this revolver is typical, then Colt certainly achieved their goal. The tight lockup and smooth action are duplicated only by those of the Python in a production revolver. This revolver is in fantastic condition with just a few faint marks in the finish that you really need to look for in order to spot. It will make an excellent addition to a Colt collection or a good choice as the first gun in a collection. This revolver will also make a great choice for someone who wants to practice target shooting with a heavy rimfire revolver with the same weight and feel as their centerfire target revolver. It is especially good for those with large hands who want or need oversized grips. This revolver has been extremely well cared for and with its box will make a great present for someone.
