Ruger Police Service-Six .357 Mag Revolver, 4-Inch Heavy Barrel, 1982 Production
The Ruger Police Service-Six is the duty-ready variant of the Security-Six series, built on a one-piece investment-cast steel frame for strength that suited law-enforcement needs of the early 1980s. This square-butt revolver features the heavy 4-inch barrel unique to the Service-Six line, a double-action/single-action system with Ruger’s transfer-bar safety, and a durable blued finish. An aftermarket one-piece rubber finger-groove grip has been fitted for improved control, giving this 1982-dated revolver a practical, shooter-oriented feel.

The Service-Six stands out for its investment-cast, side-plate-free frame that maximizes rigidity and simplifies maintenance. Ruger’s design choice results in a robust revolver that handles full-power .357 Magnum loads with confidence.
This example carries the 158- serial prefix, placing production in 1982 during the peak years of U.S. Postal Service and Border Patrol adoption. While provenance to an agency isn’t documented, the build characteristics align with the contract guns of that era.
The heavy 4-inch barrel balances the revolver and helps manage muzzle rise, while fixed iron sights—serrated ramp front and rear notch milled into the top strap—provide a snag-free, duty-focused sight picture.
An aftermarket one-piece black rubber finger-groove grip replaces the factory stocks, adding hand-filling texture and recoil control. The square-butt Service-Six grip frame makes the change seamless and solid.
With a six-shot, fluted cylinder, traditional external spurred hammer, and smooth double-action trigger pull, this revolver offers the classic wheel-gun experience in a package built for service durability.
