Deadly Manurhin MR 73

Army and Weapons | Deadly Manurhin MR 73 | Manurhin the MR73 is a French-manufactured, double-action revolver chambered in .38 Magnum Special/.357. The revolver can be converted to 9mm Parabellum supplied with a replacement cylinder. The MR73 is produced by Manurhin and is available in 3 ", 4", 5 ¼ "and 6" barrel lengths.
The MR73 is standard issue with the elite of the French police and military special weapons and tactics teams (RAID, GIGN and similar units). The GIGN chosen for the MR73 in part for its ability to indefinitely 150 rounds of ammunition to withstand full power during the practice range. These teams also use with MR73 and scopes 8 "and 10" barrels for tactical purposes.
A sporty version of the name of the MR32 is produced in .32 S & W Long. It was first produced in 1985. A variant called the Gendarmerie has adjustable rear sights and front sights higher.
The frame, cylinder, and during the MR73-certified ammunition are made of steel, alloy steel. Barrels are manufactured by cold hammering. The thread is formed during the forging process, eliminating the need to cut the thread as a separate step of the manufacturing process. This creates an extremely hard and microscopically smooth internal surface vessel.
Each match is MR73 degree, comes with a factory test target shot at 25 meters. Average of 15 rounds, no group has more than 20 mm (0.8 inches) in diameter with selected ammunition permitted.
The MR73 has an adjustable trigger weight in both double action and single action modes, a feature not found in other revolver. These adjustments do not affect the strength of the main spring, provide a reliable primer ignition. This is due to the use of roller bearings in the trigger mechanism with extensive hand fitting and polishing the parts during assembly. The MR73 requires more than 12 hours of hand-fitting the factory, causing about 50% more expensive than competing US-produced brands.
Cylinder rooms are finished with a mechanical process that makes them slippery and extremely hard. The factory proof-fire each cylinder chamber with .357 Magnum ammunition generates 30% more pressure than the CIP maximum allowable pressure for the Magnum cartridge. The plant ensures that the cylinder will not crack or exhibit deformation of a sphere or a .357 Magnum ammunition developing double the standard maximum allowable pressure of 300 MPa, which means that the cylinder 600 MPa (92,800 psi, or 46 , 4 tons per square inch) to resist.
