What’s Included
- Ruger Police Service-Six .357 Magnum revolver with installed Hogue Monogrip rubber finger-groove grip
The Police Service-Six is the fixed-sight variant of Ruger’s Security-Six family, favored by departments for its durability and straightforward operation. Investment-cast carbon-steel parts and the triple-locking cylinder give the gun a reputation for strength under heavy .357 Magnum loads.
This example retains its original 4-inch carbon-steel barrel with a partial under-lug that adds forward weight for steadier follow-up shots without excessive bulk. The serrated ramp front sight and integral square-notch rear sight offer a snag-free profile suited to duty carry.
The aftermarket Hogue Monogrip replaces the factory stocks with molded rubber finger grooves, improving purchase and recoil control while maintaining a slim profile. The exposed spur hammer supports both precise single-action fire and fast double-action work.
Serial prefix 155- confirms 1980 production, placing this revolver squarely within the era when many agencies transitioned to Ruger six-guns for their balance of cost, strength, and reliability.
