The Ruger LCR is a compact revolver built by Sturm, Ruger & Co. and announced in January 2009. LCR stands for "Lightweight Compact Revolver". It incorporates several novel features such as a polymer grip and trigger housing,^[4] monolithic receiver, and constant force trigger. At 13.5 oz (380 g),^[5] the LCR is nearly 50% lighter than the stainless steel SP101,^[6] as only the barrel and fluted cylinder are made of stainless steel.

Description

The LCR operates in double-action only (DAO), as the hammer is concealed within the frame handle's fire control housing and cannot be cocked prior to firing. In order to create a lighter trigger pull, it features a friction-reducing cam.

The LCR was originally released chambered in .38 Special. In June 2010, Ruger released the LCR-357 chambered for .357 Magnum.^[7] With the rising popularity of the LCR, in December 2011 Ruger announced the new Ruger LCR 22, chambered in .22 LR with an eight-round capacity. In the summer of 2013, Ruger introduced a .22 Winchester Magnum Rimfire (WMR) version of the LCR, with a six-round capacity. In the autumn of 2014, Ruger introduced a five-shot 9mm Luger version, and a six-shot .327 Federal Magnum version a year later.

The LCR frame is aluminum alloy and synthetic glass-filled polymer finished in matte black with Synergistic Hard Coat. Per the Ruger website, the "monolithic frame is made from aerospace-grade, 7000 series aluminum in .22 LR, .22 Magnum and .38 Spl +P models and from 400 series stainless steel in the powerful .357 Magnum, 9mm Luger and .327 Federal Magnum models."

LCRx

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.^[10][11] A 1.87-inch (47 mm) barrel version of the LCRx in .357 Magnum and a 3-inch (76 mm) barrel version in .22 Magnum and .22 LR became available in April 2017. 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.^[12]
