What’s Included
- Holster
The Model 10-6 heavy-barrel K-frame offers the classic 4-inch, square butt service layout with fixed sights, built in the United States in the early 1970s. The D-prefix serial range points to circa 1971–1972 manufacture, aligning with the three-screw frame configuration without a trigger-guard screw.
Its construction is blued carbon steel, with a heavy, pinned barrel for secure barrel fit. The hammer and trigger retain factory color case-hardening, and the revolver wears checkered walnut Magna stocks with S&W medallions for a traditional service grip profile.
Sight details include a serrated ramp front and an integral topstrap groove rear. Anti-glare serrations on the topstrap and front sight aid clear sight picture acquisition, while the checkered cylinder latch provides positive manipulation.
The ejector rod is unshrouded and locks at the front lug, consistent with the period. This double-action/single-action revolver holds six rounds of .38 Special, delivering the straightforward, dependable layout that defines the Model 10-6 Heavy Barrel configuration.
