The KGP-141 designation identifies this GP100 as the 4-inch stainless model with a heavy profile barrel and full-length underlug, a configuration valued for its balanced handling and durable construction. The barrel carries a longitudinally serrated rib that reduces glare while maintaining a clean sight picture.
Sighting equipment includes an interchangeable front sight with a red/orange insert and an adjustable rear sight with windage and elevation screws. This setup allows precise zeroing while keeping the classic GP100 sight profile.
The six-shot fluted cylinder is paired with Ruger’s push-button cylinder latch for positive, reliable operation. The revolver uses a smooth-faced trigger and an exposed hammer with a checkered spur, supporting double-action/single-action use.
Built in the United States in 1987, this GP100 is finished in brushed stainless steel across the frame, barrel, and cylinder. It retains its one-piece black rubber finger-groove grip and features Ruger’s transfer-bar safety system. The barrel is rollmarked with the Southport, Conn. U.S.A. warning legend, consistent with production of that period.
