The MR 73 was standard issue with France's Gendarmerie and in some police units including Special Weapons and Tactics teams (RAID, GIGN and comparable units). In 2021, Beretta began to import the MR 73 Gendarmerie and the MR 73 Sport into the United States.
The MR 73 has an adjustable trigger weight in both double-action and single-action modes, a feature found in other high-end revolvers such as Korth and Janz. 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.
The revolver can be converted to 9×19mm Parabellum with a supplied replacement cylinder, however, 9×19mm Parabellum under French law has the status of ammunition of war. Thus, from the early 1980s, production was limited to the versions in .38 Special/.357 Magnum.
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 C.I.P. 300.00 MPa (43,511 psi) Pmax piezo pressure, meaning the cylinder can withstand 600.00 MPa (87,023 psi), or 43.5 tons per square inch).
The frame, cylinder, and barrel of the MR 73 are made from ordnance-certified, alloyed steel. Barrels are manufactured by cold-hammering. The rifling is formed during the forging process, eliminating the need to cut the rifling as a separate manufacturing step. This creates an extremely hard and microscopically smooth internal barrel surface.
MANURHIN S.A; had made a counterweight to use with Manurhin MR 73 5"1/2 and greater length and high quality walnut pistol grip.
HKS make a speedloader (Model 10A) to use with .38, .357, and 9mm caliber cylinder.
A sporting variant called the MR 32 Match is produced in .32 S&W Long. It was first produced in 1985. Other sporting variants are the MR 38 Match chambered in .38 Special and the MR 22 Match chambered in .22 Long Rifle. The Match versions feature only a single action trigger and have an extended rearward rise. This allows the aiming length to be increased without increasing the total length of the weapon, which would have made it exceed the maximum dimensions authorized in certain competitions.
A variant called the Gendarmerie features adjustable rear sights and larger front sights.
