The SP101 is Ruger's compact all-steel small-frame revolver, built heavier than comparable J-frame Smiths to handle .357 Magnum without punishing recoil. The 2.25-inch barrel is the most common configuration, suited for concealed carry. At 26 oz, it is significantly heavier than polymer snubs but offers a more controllable .357 experience.
