Manurhin's MR73 .357 Magnum Revolver was developed for use by French police and Special Weapons and Tactics units, including the legendary GIGN, who needed a reliable sidearm for use in the field and could stand up to their incredibly punishing training regiments that involve firing 150 rounds at daily target practice. Every aspect of the MR73 has been optimized for high performance, it features a unique trigger system that delivers one of the smoothest trigger pulls ever found on a double action with zero-creep. The cylinder of the MR73 is fully machined from forged, ordnance-certified steel billets, and the chamber finish is conducted by an impact process resulting in remarkably smooth chamber walls and long service life.
