SMITH & WESSON MODEL 29 - a six shot, double action revolver chambered for the .44 Magnum cartridge and manufactured by the United States company Smith & Wesson. The Model 29 was offered with 3", 4", 5", 6", 6½", 8⅜" and, later, 10⅝" barrel lengths as standard models. Other barrel lengths were available either by special order from Smith & Wesson's Custom Shop or custom built by gunsmiths. The 5" barreled variant had a full length underlug. Finish options available included a highly polished blued or nickel-plated surface. At the time of its introduction the Model 29 was the most powerful production handgun, although it was later overtaken by handguns chambered for the even larger .454 Casull and .50 Action Express cartridges.
