Ruger cataloged this configuration as BKH36X, pairing a 6.5-inch carbon-steel barrel with an alloy grip-frame to balance weight and handling. The blued finish complements smooth walnut grips capped by silver Ruger medallions.
The protected-ear topstrap houses a fully adjustable square-notch rear sight, matched to a pinned ramp front sight with a serrated blade for a clear, precise sight picture.
Collectors prize Old Model Blackhawks for their original three-screw action. This example remains unconverted, preserving the factory lockwork that defines the early production era.
The convertible system adds convenience: swap to the included fluted 9 mm cylinder to shoot widely available Luger ammunition, then return to the .357 Magnum cylinder for full-power revolver loads—all without modifying the gun.
Serial prefix 30- indicates 1971 manufacture, placing this revolver squarely in the desirable pre-1973 production window before Ruger introduced later design changes.
