Ruger GP100 Match Champion (1755)

Ruger GP100 Match Champion .357 Magnum (Model 1755)

The Ruger GP100 Match Champion .357 Magnum (Model 1755) is purpose-built as a refined evolution of the GP100 platform, pairing Ruger’s proven DA/SA revolver architecture with factory competition enhancements. In this adjustable-sight configuration, the revolver balances quickly, presents a high-visibility sight picture, and maintains the rugged reliability for which the GP100 line is known.

At the core is a stainless-steel frame and a 4.2" slab-sided, half-lug barrel. The half-lug profile trims forward weight for faster transitions while preserving enough mass for recoil control. Ruger finishes the steel in satin stainless to resist corrosion and wear. The barrel features an 11° target crown intended to help protect the rifling at the muzzle and support consistent accuracy. Inside, the bore uses a right-hand 1:18.75" twist with five grooves, a specification long associated with stable performance across common .357 Magnum bullet weights.

Model 1755 is equipped with an adjustable rear sight and a fiber-optic front, giving shooters a bright and precise aiming reference in varied lighting. The Match Champion series uses Novak-pattern components on the sights, and this variant’s set-up is optimized so you can fine-tune elevation and windage for your chosen load and distance. Complementing the sight system is a stippled Hogue hardwood grip that locks into the hand without abrasive texture, encouraging consistent placement and trigger control in extended strings of fire.

Ruger’s mechanical design emphasizes durability and safety. The triple-locking cylinder engages the frame at the front, rear, and bottom for positive alignment and dependable lock-up. A transfer-bar mechanism prevents the hammer from contacting the firing pin unless the trigger is deliberately pressed, offering a built-in layer of drop safety without a manual safety lever. Field maintenance is straightforward: the GP100 family breaks down into integrated subassemblies without special tools, simplifying cleaning and inspection.

Factory action work is a hallmark of the Match Champion line. Ruger polishes and optimizes internal bearing surfaces, and incorporates a centering boss on the trigger and shims on the hammer. The result is a smooth, even double-action pull and a crisp single-action break that is consistent shot to shot. These refinements, paired with the revolver’s 38 oz (approx.) weight and the controllable .357 Magnum chambering, make the platform suitable for both competitive formats and demanding practice cycles.

Dimensionally, the Ruger GP100 Match Champion .357 Magnum (Model 1755) measures 9.50" overall with the 4.2" barrel and weighs 38 oz. Capacity is six rounds. Ruger catalogs the model under KGP-141-MCA with UPC 736676017553. As a .357 Magnum revolver, it can also accept .38 Special and .38 Special +P cartridges, allowing shooters to tailor recoil and performance for training or competition; proper chamber cleaning and ammunition selection remain essential.

For users planning holster carry or duty use, the half-lug barrel aids re-holstering while the contoured cylinder reduces drag. The revolver’s grip-frame architecture accepts a wide range of aftermarket grips if a different contour is desired, though many shooters find the included Hogue hardwood stocks deliver a solid blend of retention and comfort. The topstrap carries the adjustable rear sight; the revolver does not include an optics rail, but aftermarket solutions exist if an optical sight is later required. From the factory, the configuration remains elegantly simple and focused on iron-sight performance.

In sum, the Ruger GP100 Match Champion .357 Magnum (Model 1755) combines the GP100’s tank-like construction with meaningful competition-ready upgrades. Shooters seeking a stainless, adjustable-sight, medium-frame revolver with a balanced 4.2" barrel will find that this Match Champion variant offers a capable, safety-forward choice with quality-of-life improvements that are immediately noticeable on the range.
