MR-73 revolvers were developed by MANURHIN company of France in 1973. MR-73 is a standart issue firearm of the french Gendarmerie, as well as of some French elite law enforcement agencies (G.I.G.N., R.A.I.D. etc). MR-73 is also a favorite European sporting arm, available also in Sport and Match (.32 SW Long or .38 Spl).
All MR-73s featured all-steel construction, designed to withstand extereme pressures. MR-73 barrels are manufactured by cold-hammering, resulting in long service life and extreme accuracy. Additional cylinders for 9x19mm Luger ammunition available as options, providing ability to use cheaper ammunition for ectensive training. All MR-73's had hand-assembled and ajusted actions, resulting very good to extremely high accuracy and high unit price. Reliability and service life of the MR-73s, combined with the match-grade accuracy, also brings it to the worlds' best service handguns class, along with SIG P-210.
Every MR73 is match grade accurate, shipped with its own factory test target fired at 25 meters. Averaging 15 rounds, no group over 20mm (0.8 inch) diameter with selected ammunition is allowed.
The MR73 has an adjustable trigger weight in both double-action and single-action modes- a feature not found in any other revolver. These adjustments do not alter the strength of the main spring, ensuring reliable primer ignition. This is due to the use of roller bearings in the trigger mechanism along with extensive hand fitting and polishing of components during assembly. The MR73 requires more than 12 hours of hand-fitting at the factory, making it about 50% more expensive than competing U.S.-manufactured brands.
Cylinder chambers are finished with an impact process that makes them glass-smooth and extremely hard. The factory proof-fires each cylinder chamber with .357 Magnum ammunition generating 30% more pressure than the C.I.P. maximum allowable pressure for the Magnum cartridge. The factory guarantees that the cylinder will not burst or show any bulging or deformation with .357 Magnum ammunition developing double the standard maximum allowable pressure of 300 MPa, meaning the cylinder can withstand 600 MPa (92,800 psi, or 46.4 tons per square inch).
