The SP101 with 2.25-inch barrel is Ruger's compact .357 Magnum carry revolver. The SP101 is substantially heavier than the S&W J-frame it competes with, which helps tame the substantial recoil of full-power .357 Magnum from a 2-inch barrel. The all-stainless construction and solid-frame design make it nearly indestructible. This is the primary concealable .357 Magnum revolver in the Ruger lineup.
