Colt Trooper MK III .357 Mag. Revolver, 6-Inch, 1975 Production – Polished Blue, Pachmayr Grips
Built in 1975, this Colt Trooper MK III represents the first generation of Colt’s medium-frame revolvers to incorporate a modern transfer-bar safety system. The six-shot wheel gun features a 6-inch heavy barrel with a solid rib and partial shroud, giving it the accuracy benefits of a Python at a more approachable price. Its factory-polished blue finish remains highly regarded by Colt enthusiasts, and the aftermarket Pachmayr Presentation wrap-around grips add secure, recoil-absorbing control.

The Trooper MK III is built on Colt’s unique medium J-frame, engineered specifically for the MK III series. This frame supports the transfer-bar system that blocks the hammer unless the trigger is fully pressed, adding confidence for everyday carry or range work.
Its 6-inch heavy carbon-steel barrel, complete with a solid rib and partial ejector-rod shroud, delivers excellent balance and consistent point-of-aim stability. Combined with the wide checkered hammer spur and smooth-face trigger, the revolver offers controlled double-action pulls and crisp single-action breaks.
Fully adjustable iron sights—serrated ramp front and square-notch rear—allow precise zeroing with a variety of .357 Mag. or .38 Spl. loads. Collectors appreciate the polished factory blue that defined Colt’s 1970s production, while shooters benefit from the comfortable Pachmayr grips that dampen recoil without altering the gun’s classic lines.
With its 1975 manufacture date and strong cosmetic condition, this Trooper MK III stands out as both a capable range revolver and a desirable addition to a Colt collection.
