The GP100 platform is known for its triple-locking cylinder that secures at the front, rear, and bottom for rock-solid alignment under recoil. This .327 Federal Magnum version adds a seventh chamber without enlarging the frame, giving you one extra round compared to traditional six-shot revolvers.
The 4.2-inch stainless barrel features a full underlug for optimal balance and a serrated top rib to cut glare. Paired with fully adjustable iron sights—a black-blade ramp front and square-notch rear—it provides a clear sight picture and easy zeroing for different loads.
.327 Federal Magnum offers .30-30-like velocities from a revolver while staying compatible with several lower-pressure .32-caliber cartridges, expanding ammunition choices for range work or small-game hunting. The 1:16-inch right-hand twist and six-groove rifling stabilize common bullet weights cleanly.
Ruger’s transfer-bar safety prevents the hammer from reaching the firing pin unless the trigger is pulled, and the external spur hammer supports both single- and double-action fire. The modular grip peg accepts various aftermarket stocks; this example wears the factory Hogue Monogrip that tames recoil and fits most hand sizes.
Every major component—frame, barrel, and seven-shot cylinder—is satin-finished stainless steel, giving the revolver excellent corrosion resistance and an understated appearance that hides holster wear. All told, this GP100 combines collectible status, flexible chambering, and rugged construction in one well-kept package.
