This Trooper MK III combines Colt's Mark III engineering with a robust, all-steel build. The transfer-bar ignition and coil-spring internals defined the series, delivering a dependable DA/SA action in a medium-frame package chambered for .357 Magnum.
The revolver wears a polished blue finish over carbon-steel frame, receiver, and cylinder. Its heavy-profile barrel incorporates a solid rib and an ejector-rod shroud, with a knurled ejector-rod tip for confident manipulation. The six-shot fluted cylinder uses Colt's rearward-pull cylinder latch.
Sighting equipment includes a pinned, serrated-ramp front sight paired with a fully adjustable rear. The external hammer has a checkered spur for positive control. Stocks are checkered walnut with silver Colt medallions, completing a classic Colt presentation.
Manufactured in 1976 in the United States, this example sits squarely in the 1970s era of Colt production. The L-prefix serial range aligns with MK III production of that period, and the frame carries the Colt Rampant Pony logo.
