The Colt Trooper MK III occupies a distinct place in revolver history as a purpose-built, user-focused firearm offering robust performance without the premium price of its higher-end stablemates. Designed and produced between 1969 and 1983, this medium-frame double-action revolver was aimed at law enforcement and civilian shooters who wanted durability and practical accuracy in a six-shot platform.

Design and Mechanicals

The MK III represents a departure from older Colt internals. Its new “J” frame and modern coil-spring action replaced the labor-intensive flat springs of previous generations, improving serviceability and reducing production costs while maintaining solid function. For safety, Colt introduced a transfer-bar system on this series—preventing the hammer from contacting the firing pin unless the trigger is fully depressed, a valuable passive safety feature.

Action, Capacity and Trigger

This is a six-round revolver offering smooth single-action and reliable double-action pulls. The MK III’s trigger characteristics are well-regarded for a production revolver of its era, delivering predictable break and reset suitable for precision shooting and practical use.

Barrel, Sights and Ergonomics

The 8″ barrel variant is notable for its heavy barrel profile, solid top rib, and shrouded ejector rod—features that reduce barrel droop and improve balance for precision work. Standard fully adjustable iron sights paired with walnut target grips make the 8″ MK III a comfortable and accurate option for target shooting and hunting at extended ranges.

Caliber and Practical Applications

Chambered for .357 Magnum, the COLT TROOPER MK III can also safely fire .38 Special and .38 Special +P ammunition, giving shooters flexibility for range practice and defensive loads. The 8″ barrel enhances ballistic performance—higher velocity, flatter trajectory, and improved sight radius—making this configuration well suited for handgun hunting, silhouette, and precision range work. At a price of $1,250.99, it represents a focused value for collectors and shooters seeking Colt durability without premium Python pricing.

Buying Notes

Colt’s MK III line is notable for bringing modernized internals and practical safety to a medium-frame revolver. If you prioritize a heavy-barrel 8″ platform for accuracy and stable handling, this model is worth evaluating. Check current availability
