The SP101 platform is known for strength, and this example features a monolithic stainless-steel frame and Ruger's triple-locking cylinder for precise alignment and consistent lockup. The fluted 5-chamber cylinder reduces weight without sacrificing durability.
The short 2.25-inch stainless barrel uses a 1:16 RH twist with conventional 5-groove rifling. A full underlug and ejector-rod shroud are integrated for protection and balance. Sights are fixed, with a pinned, replaceable black ramp front and an integral rear notch.
This double-action/single-action revolver uses a smooth trigger, a spurred and knurled hammer, and Ruger's transfer-bar safety system. The compact size and 26 oz weight pair with black rubber finger-groove grips for a secure hold.
Finished in polished stainless across the frame, cylinder, and barrel, this model aligns with Ruger catalog reference KSP-321X (Ruger 5718). It is chambered in .357 Magnum with a 5-round capacity and an overall length of 7.20 inches.
