The GP100’s stainless steel frame, cylinder, barrel, and receiver all wear a uniform satin stainless finish. The 6-inch barrel uses a full underlug and a serrated top rib, giving it a classic GP100 profile with practical sighting surfaces. The fluted six-shot cylinder maintains the revolver’s six-round .357 Magnum capacity while complementing the robust build.
This is a double-action/single-action revolver with an exposed hammer and checkered spur for controlled cocking. A smooth-faced trigger and Ruger’s transfer bar safety system round out the fire-control setup. The triple-locking cylinder enhances alignment and durability under repeated use.
Sighting is fully user-configurable with an adjustable target rear sight and an interchangeable ramp front sight that uses a push-button release. The black rubber monogrip has finger grooves, textured panels, and Ruger medallions for a secure, consistent hold.
Technical details include a 1:18.75 in right-hand twist with 5-groove rifling, an overall length of 11.50 inches, and a 45 oz weight. As a 2016 production gun, this example is designated Model 1707 (catalog KGP-161) and incorporates Ruger’s modular subassemblies that allow tool-less maintenance.
