Ruger GP100 KGP-161 .357 Magnum Revolver – 6" Full-Lug Satin Stainless, 1991 Production, with Factory Box
This 1991 Ruger GP100 KGP-161 pairs the platform’s renowned strength with desirable early-production features, including the discontinued Lett rubber grip with hardwood inserts and a six-inch full-lug barrel topped by a pinned red-ramp front sight. Built entirely from satin-finished stainless steel, it offers a robust triple-locking cylinder, a transfer-bar safety system, and the versatile double-action/single-action trigger that has made the GP100 a favorite for duty, hunting, and range use. The revolver is accompanied by its original Ruger factory yellow/black two-piece cardboard box with a matching serial-number label.

The six-inch, full-lug barrel enhances balance and recoil control, making this variant popular for silhouette shooting and handgun hunting. The solid rib profile and pinned red-ramp front sight combine with a fully adjustable white-outline rear sight for a crisp sight picture.
Ruger’s one-piece grip-frame design increases structural strength while simplifying grip changes. This revolver retains the early Lett black rubber grip with hardwood inserts, a feature discontinued after 2008 and now sought after by enthusiasts.
The GP100’s triple-locking cylinder secures at the front, rear, and bottom, ensuring reliable lockup under heavy .357 Magnum loads. The smooth combat-style trigger offers consistent double-action pulls and a clean single-action break, aided by the spurred hammer for deliberate precision shots.
Manufactured in the United States, this KGP-161 carries Ruger’s satin stainless finish across the frame, barrel, and six-shot cylinder, providing corrosion resistance for field or duty environments. Its 1:18.75" right-hand twist rate stabilizes a wide range of .38 Special and .357 Magnum bullet weights.
