Ruger's LCR is a lightweight, small-frame revolver with a uniquely smooth trigger and highly manageable recoil. It features a monolithic frame with a grip peg allowing for use of a variety of grip styles, and an extensively fluted, high-strength stainless steel cylinder with a PVD finish for excellent durability. The patented, friction-reducing cam is a next generation design in fire control systems resulting in a smooth, non-stacking trigger pull. Its patented, polymer fire control housing holds the fire control components in their proper dimensional relationships, reduces weight significantly, and helps reduce recoil. LCR revolvers have a replaceable, pinned ramp front sight with white bar. LCRx models feature an external hammer that allows it to be fired in single-action mode. LCRx revolvers in 22 WMR have a frame made from aerospace-grade, 7000 series aluminum. This model has a matte black finish with a 1.87" barrel, integral u-notch rear sight, and is fitted with a black Hogue Tamer Monogrip.
