In the summer of 2013, Ruger introduced a .22 Winchester Magnum Rimfire (WMR) version of the LCR, with a six-round capacity.

The LCR frame is aluminum alloy and synthetic glass-filled polymer finished in matte black with Synergistic Hard Coat.

Ruger announced the LCRx variant in December 2013,[8] which features an external hammer, allowing it to be fired in single-action or double-action.

[9] All the other features of the LCR are also present in the LCRx including the polymer grip, trigger housing, and fluted stainless steel cylinder.

The 1.87-inch barrel version became available as a five-shot 9mm Luger and a six-shot .327 Federal Magnum in the fall of 2017.
