When it was originally introduced, the Ruger LCR® was one of the most significant new revolver designs in over a century and has since been awarded three patents. The new LCRx in .357 Magnum maintains all the features of the original LCR, including Ruger's patented friction-reducing cam, a next-generation design in fire control systems that results in a smooth, non-stacking trigger pull. The double-action trigger pull force on the LCR builds gradually and peaks later in the trigger stroke, resulting in better control and a lighter felt trigger pull. The LCRx also incorporates crisp single-action functionality for precise shooting.

The LCRx is equipped with an integral u-notch rear sight and a pinned, white ramp front sight for quick target acquisition. The Hogue® Tamer™ Monogrip® with finger grooves provides outstanding control under recoil. The LCRx chambered in .357 Magnum has three main components: a polymer fire control housing, a stainless steel monolithic cylinder frame and an extensively fluted stainless steel cylinder.
