Features 

The transfer bar safety allows the Vaquero to be carried with all six chambers loaded safely — an important update over older single-action designs that required an empty chamber under the hammer. Fixed blade front and integral U-notch rear sights are standard single-action fare: simple, durable, and appropriate for the distances this gun is typically used at. 
 
The single-action mechanism requires cocking the hammer before each shot, which is the defining characteristic of this style and what cowboy action competitors specifically train around. The high-gloss stainless finish is more visually prominent than the satin stainless on most working guns, so it's a deliberate aesthetic choice on this version.

The Vaquero in .45 Colt stainless with star grips gets appreciation from a specific crowd: cowboy action shooters and single-action enthusiasts who chose it for its combination of Ruger's transfer bar safety and the classic single-action look.

Build quality and finish are the most-praised aspects. The stainless construction is considered durable, and the high-gloss finish is well-executed. The hardwood star grips get specific positive comments for feel and aesthetics.

Action smoothness is a common topic. Many owners note that the action improves with use and dry-fire practice. Cowboy action competitors often do trigger work or slicking jobs on the internals, which is normal for the platform.

Weight and size come up as practical notes. At 40 oz, the Vaquero is substantial — not an everyday carry gun, and some users find extended range sessions tiring. For its intended cowboy action use, the weight is generally accepted.

Price occasionally comes up. Some buyers feel alternatives in the single-action market offer similar functionality for less. Most Ruger buyers cite the transfer bar safety and warranty support as the reasons they chose the Vaquero over imported alternatives.
