Ken - the Smokewagon comes in several different calibers, and the two versions - the 'Smokewagon" and the "Taylor tuned Smokewagon" Exclusively from Taylor's & Co., The Smoke Wagon™ is a second-generation, stagecoach-style, single-action revolver. It boasts a low-sitting hammer and wider-style sights that allow for faster sight acquisition. It also features a blue finish with a case-hardened frame, and a thin, richly detailed, checkered grip for comfort and improved aim. All of these features are available on both the standard and Taylor Tuned version of The Smoke Wagon™. Taylor Tuned actions are performed by our own in-house gunsmiths and feature: hand polishing, exact timing, and lighter hammer/trigger pull with our custom springs. The Taylor Tuned Smoke Wagon™ features one of the smoothest hammer and trigger pulls on the market.

Ken, the difference I see is the "Short Stroke" version has an "Octagonal Barrel". The Non Short Stroke has a "Round Barrel".
