- Ruger SP101 .357 Mag. revolver (Model 5771, KSP-341X)
The SP101 configuration here is the 4.20 in, adjustable-sight model identified as KSP-341X. It was manufactured in 2019 and built in Ruger’s Newport, New Hampshire facility. The compact 5-round cylinder pairs with .357 Magnum chambering to deliver a carryable format with proven performance.
The revolver is constructed entirely from stainless steel, finished in satin stainless on the frame, barrel, cylinder, and receiver. The barrel features a full underlug and ribbed top, while the fluted cylinder incorporates a shrouded ejector rod. Ruger’s triple-locking cylinder and push-button cylinder latch provide solid lock-up and intuitive operation.
Sighting is fast and tunable thanks to the pinned green fiber-optic front blade and a fully adjustable rear sight. The exposed hammer with a checkered spur supports DA/SA operation, and the transfer bar serves as the safety mechanism. The black rubber grips with checkered wood inserts and Ruger medallions offer a secure, classic feel.
Key dimensions include a 4.20 in barrel, 9.12 in overall length, and a weight of 29.5 oz. The barrel uses a 1:16 RH twist with 5-groove rifling, aligning with the model’s accuracy-oriented setup.
