Bryant Ridge's Analysis:
The Colt Trooper Mark III represents the high-water mark of Colt’s mid-20th-century production revolvers — a premium, target-oriented member of the Trooper family that married rugged service-grade construction with true competition features. Built on Colt’s robust medium-frame platform, the Mark III was offered with heavy, shrouded barrels in 4", 6", and later 8" lengths to provide a stiff sight radius and reduced muzzle flip for follow-up shots. From the factory, it was fitted with adjustable target sights, Target grips, a pronounced target hammer, and Colt’s first dedicated “Target” trigger — a combination that produced a much crisper, flatter single-action break and more controllable double-action pull than the brand’s standard service models. Caliber offerings were broad: popular centerfire chamberings included .357 Magnum (with a few special law-enforcement orders in .38 Special), while rimfire variants were produced in .22 LR and .22 Magnum, making the Mark III useful both as a serious match or hunting revolver and as a lower-recoil trainer or small-game option. On the range, the Trooper Mark III’s mass, long barrel, and target controls deliver an inherently steady shooting platform that rewards careful aiming and deliberate trigger work — traits that made it popular with competition shooters, handgun hunters, and officers who wanted a muscle-memory friendly service pistol with target capability. The heavy shrouded barrel improves balance and felt recoil, the adjustable rear sight enables precise zeroing with a variety of loads, and the target trigger and hammer noticeably improve single-action accuracy compared with standard service triggers. Finish options added to the model’s appeal and market differentiation: a new high-gloss bright blue-black, bright nickel, and a satin electroless nickel finish (marketed by Colt as “Coltguard”) — the latter often mistaken for stainless due to its muted, corrosion-resistant appearance. Today, the Trooper Mark III is sought after by collectors and shooters who prize a vintage Colt that actually shoots like a target gun; long-barrel examples, special-order calibers, and well-preserved finishes command premiums. Practical ownership notes: despite Colt’s generally solid parts support, buyers should inspect for timing, cylinder lockup, and worn forcing cones on older examples, and a light gunsmith tune (timing, trigger smoothing, and sight regulation) will often return an aging Mark III to peak performance.
