The MK III series introduced Colt's coil-spring, modular lockwork, delivering a robust internal design paired with a transfer-bar safety. This Trooper MK III maintains the classic Colt rearward-pull cylinder latch and external hammer layout, with the hammer sides finished in color case-hardening and a checkered spur for positive control.
The 6-inch carbon steel barrel features a non-ventilated, serrated rib, a partial underlug with ejector-rod shroud, and a pinned serrated ramp front sight. The topstrap is matte and serrated to reduce glare, complementing the fully adjustable square-notch rear sight for precise sight alignment.
Constructed of carbon steel throughout, the frame, receiver, and cylinder wear Colt's polished blued finish. The checkered walnut, target-style stocks with silver Colt medallions provide a secure grip and period-correct aesthetics.
