The KGP-141 configuration pairs a 4-inch, heavy, full-underlug barrel with a stainless-steel frame and cylinder, all finished in brushed/satin stainless. The barrel features an integral ejector-rod shroud for a clean, rigid assembly.
This GP100 runs in double-action/single-action with a smooth-faced trigger and an exposed hammer with a checkered spur. Ruger's transfer-bar safety is standard, providing reliable ignition while keeping the firing pin protected.
Built without a sideplate, the solid-frame design works with a triple-locking cylinder for secure lockup. The peg-style grip frame is fitted with a one-piece black rubber grip featuring smooth hardwood insert panels.
Sighting equipment includes a ramped front sight with a red/orange insert and a fully adjustable rear sight for windage and elevation. Chambered in .357 Magnum with a 6-round cylinder, this USA-made revolver reflects the classic GP100 setup from its 1990 production year.
