Colt Diamondback 4" 1981

Wiki-history, The Colt Diamondback is a revolver manufactured by Colt's Manufacturing Company of Hartford, Connecticut, in calibers of .22 LR and .38 Special. Inspired by the successful Colt Python, the Diamondback was manufactured from 1966 to 1988 and was available in barrel lengths of 2½, 4, and 6 inches. Colt introduced the double-action Diamondback as a deluxe model in 1966.[1] It has a wide serrated target hammer, ventilated rib, fully adjustable target quality sights, and full-length barrel underlug.[1] It is a 6-shot revolver with a swing-out cylinder and was available in blue or nickel finishes.[1] Visually, the Diamondback resembles a scaled-down version of the Python, though the action was not tuned as finely as the Python, nor did it receive the Python's Royal Blue finish.[1][2] While the Python is built on Colt's "I frame," the Diamondback is built on the smaller "D frame," as used in the Detective Special. The Diamondback was dropped from production in 1988.[3]
