Commissioned by Sturm Ruger as an upgrade to the SR line of pistols, the LMS-RMSR provides a decisive advantage in low light. This clever design offers superior integration with the sleek lines of the pistol frame and an integral Picatinny rail for the attachment of a tactical light. Advanced programming enables the operator to select from a steady or pulsed beam option for superior visibility and faster target identification. This product is also compatible with SR22, SR9, and SR40 pistols.
