Manurhin RMR
Manufacture de Machines du Haut-Rhin (Manurhin) · Revolver · Discontinued · 1981
Also known as: Ruger-Manurhin Revolver
Overview
The Manurhin RMR is a French double-action revolver chambered in .357 Magnum, developed in the early 1980s as a more affordable service sidearm for the French National Police to succeed the precision-built but costly Manurhin MR 73. It was the product of a joint venture between Manurhin and the American firm Sturm, Ruger & Co.: Ruger supplied the frame and lockwork using its investment-casting (micro-fusion) techniques, while Manurhin manufactured the barrel and cylinder to the same standard as the MR 73. Produced only from 1981 to 1984, the RMR was relatively short-lived and was eventually replaced in French police service by the Manurhin Special Police F1.

Notes
The frame and mechanism were cast by Sturm, Ruger & Co. while the barrel and cylinder were made by Manurhin. Investment casting made the RMR less expensive to produce than the fully machined MR 73.
Background
The RMR grew out of the French National Police's need for a cheaper alternative to the superbly engineered but expensive Manurhin MR 73. By partnering with Sturm, Ruger & Co., Manurhin could substitute investment-cast components for labour-intensive forged-and-machined parts while keeping the Manurhin-made barrel and cylinder, blending French and American manufacturing.
