The Ruger Vaquero is a six-shot single-action revolver manufactured by Sturm, Ruger & Co. based on the New Model Ruger Blackhawk frame and was introduced in 1993. It comes in blued steel, case colored, and a gloss stainless finish (the latter gloss stainless finish is intended to resemble closely a 19th-century nickel-plated finish), all of which are available with wood, hard rubber, simulated ivory or black micarta grips and fixed sights. It arose with the popularity of Cowboy Action Shooting from which came demand for a single-action revolver that was more traditional in appearance.
