The 6-inch stainless steel barrel uses a heavy profile with a full underlug and a serrated rib. This configuration, paired with stainless construction throughout, gives the GP100 its well-known robustness and consistent sight alignment on target.
Built on Ruger's one-piece stainless frame with an integral topstrap, this GP100 employs a triple-locking, six-shot fluted cylinder. The brushed/satin stainless finish is carried across the frame and cylinder for a uniform, durable appearance.
Action is double-action/single-action with a smooth-faced trigger and an exposed, checkered hammer spur. A transfer bar safety system provides reliable, modern ignition protection.
Sights are iron: a ramped front blade and a fully adjustable rear. The revolver wears Ruger's Hogue-style black rubber finger-groove monogrip with a molded Ruger eagle emblem for a secure, consistent hold.
This example is chambered in .357 Magnum with a six-round capacity. It is Ruger Model 1707, commonly referenced as KGP-161, and was manufactured in 2016.
