The Ruger Vaquero® SASS® Model 5133 is a special competition-oriented version of Ruger’s classic single-action revolver, developed for the Single Action Shooting Society (SASS) and cowboy-action shooting. Chambered in .357 Magnum and also capable of firing .38 Special, Model 5133 features a 4.62-inch barrel, high-gloss stainless-steel construction, lowered Montado-style hammer, competition-oriented sights, and distinctive SASS grip medallions.
What makes Model 5133 particularly distinctive is that Ruger packages these revolvers as a matched two-gun set with consecutive serial numbers. Each revolver carries a special serial number beginning with the “SASS” prefix, and the pair is supplied together in a fitted red carry case. This factory-paired configuration was specifically designed with cowboy-action competitors in mind.
The revolvers are constructed from stainless steel with a high-gloss finish, providing the traditional appearance of a polished single-action six-shooter along with the durability and corrosion resistance of stainless construction. Each revolver uses a 4.62-inch (4-5/8") barrel, giving the pair traditional proportions and quick-handling characteristics.
A major feature of the SASS model is its lower and wider Montado-style hammer. The profile places the hammer spur in a more accessible position for shooters who rapidly manipulate the hammer during single-action competition. Ruger specifically developed this configuration around the demands of SASS-style shooting.
The sighting system is similarly straightforward. Each revolver uses a traditional blade front sight paired with a wider 0.140-inch rear sight notch, providing a more open sight picture than a conventional narrow-notch fixed-sight revolver.
Ruger equips the SASS Vaquero with black checkered hard-rubber grips featuring distinctive SASS medallions. These grips reinforce the special-edition character of the revolvers while maintaining the traditional profile expected from a cowboy-action firearm.
The Vaquero platform itself uses a mid-sized steel frame designed to reproduce the size, handling characteristics, and traditional appearance associated with classic Old West single-action revolvers. Ruger's reverse-indexing pawl positively aligns the cylinder with the loading-gate cutout to simplify loading and unloading, while a beveled cylinder helps facilitate smooth holstering.
For modern safety, Ruger's single-action design incorporates a transfer-bar mechanism, allowing all six chambers to be safely loaded when the revolver is handled in accordance with Ruger's instructions.
For cowboy-action shooters, collectors, or customers looking for something more distinctive than a standard Vaquero, Ruger Model 5133 stands apart because it is sold as a factory-matched pair specifically configured for SASS competition.
