What’s Included
- Ruger SP101 .357 Magnum revolver (Model 5771)
The SP101’s stainless-steel frame, cylinder, and 4.20" barrel wear a uniform satin finish that resists the elements and hard use. The 5-shot fluted cylinder locks at front, rear, and bottom for robust alignment, and the solid steel sidewalls eliminate side plates for added strength.
The barrel includes a full underlug with an ejector shroud and a serrated rib, paired with a pinned green fiber-optic front sight and a fully adjustable square-notch rear. This sight setup offers a bright front reference and precise rear adjustment for different loads.
Operation is double-action/single-action with a spurred hammer and Ruger’s transfer-bar safety system. Factory stocks are black rubber with hardwood inserts and Ruger medallions, providing a secure, hand-filling hold without adding unnecessary bulk.
Internally, the barrel is cut with a 1:16" right-hand twist and 5 grooves. Overall length is 9.12" with a weight of 29.5 oz, delivering a steady, controllable platform for .357 Magnum and .38 Special loads. Marked “READ INSTRUCTION MANUAL – RUGER NEWPORT, NH USA,” this revolver was manufactured in 2015 in the USA.
