Sturm, Ruger & Co. · Revolver · In Production · 2016
Also known as: Ruger LCRx 22 Magnum, Ruger LCRx Model 5439
Overview
The Ruger LCRx .22 WMR is a lightweight, small-frame double-action revolver chambered for the .22 Winchester Magnum Rimfire cartridge. Part of Ruger's Lightweight Compact Revolver (LCR) family, the LCRx adds an exposed hammer that allows both single-action and double-action fire, unlike the hammerless LCR. It pairs a monolithic aerospace-grade 7000-series aluminum frame with a high-strength stainless steel PVD-coated cylinder holding six rounds, and uses Ruger's patented friction-reducing cam for a smooth double-action trigger pull. Marketed primarily as a concealed-carry and personal-defense revolver, its low-recoil rimfire chambering also makes it popular for training and small-game use.

Origin
Country of origin: United States
Notes
Offered in a 1.87-inch barrel (Model 5439) and a 3-inch barrel (Model 5437); both hold six rounds. The exposed hammer distinguishes the LCRx from the double-action-only LCR.
Background
Ruger's LCR series pioneered the polymer/aluminum monolithic-frame small revolver in 2009, and the LCRx variant answered demand from shooters who wanted the option of a lighter single-action trigger pull for precise shots.
