What’s Included
- Colt Trooper MK III .357 Magnum revolver
The Trooper MK III is built on a carbon steel frame, cylinder, and barrel with a uniform polished blued finish. The checkered walnut stocks with Colt medallions provide a classic grip profile and visual contrast to the deep blueing, while the exposed hammer and smooth-face trigger reflect the period-correct control layout.
Its heavy-profile barrel incorporates an integral ejector-rod shroud and a ribbed sighting plane. Sighting is handled by a pinned ramp front with an orange/red insert and a fully adjustable rear, giving fine control over point of aim. The fluted six-chamber cylinder and knurled ejector rod support reliable operation and positive extraction.
This Mark III-series revolver uses a transfer-bar safety system and operates in both double-action and single-action modes. The checkered hammer spur aids cocking for precise single-action shots, while the smooth trigger face supports consistent double-action presses.
Factory markings include the Colt Rampant Pony logo on the sideplate, left-barrel rollmark "TROOPER MK III" with ".357 MAGNUM CTG," and right-barrel rollmark "COLT'S PT. F. A. MFG. CO.
HARTFORD, CONN. U.S.A." As part of the Colt Mark III family produced from 1969 to 1983, this example dates to 1977 and represents the mature phase of the series.
