mr73 fact check

  1. All major components of the Manurhin MR73 are milled on a five-axis CNC machine out of appropriately shaped hot forgings. Its cylinder chambers are finished by galetage, i.e. roller burnished after drilling. There are no MIM parts in the MR73, with the possible exception of the currently employed LPA rear sight.

  2. Most Manurhin revolver models, including, but not limited to the fixed sights MR73 Police/Défense variants, the MR22 Match and Junior, the 10¾" MR22 and MR73 Silhouette, the Modèle convertible .22–.32–.38, the RMR and F1 Spécial Police, the MR93 and MR96, and the Remora 5, have been definitively put out of production since Manurhin withdrew from small arms manufacture in 1998. Chapuis makes only the adjustable sights versions of the MR73 and MR88 chambered in .357 Magnum, and the single action MR38 and MR32 Match.

  3. Standard MR73 barrels are rifled with six grooves, with a right hand twist at a one turn in 476mm rate, replicating Smith & Wesson’s traditional rate of one turn in 18¾". Match barrels utilize five grooves at the same twist rate, with a bore diameter of 9.05mm. Up to serial number 39200, the bore diameter of standard MR73 barrels measures 8.96mm +0 / +0.03mm. After it, the barrels are finished to the .38 Match bore size, measuring 9.04mm +0 / +0.05mm. For obvious reasons, only the former play nice with the 9mm Para cylinder, though a few of the latter have been so (retro)fitted.

  4. All Chapuis MR73 revolvers are numbered with an HA prefix. Over the past 22 years, fewer than 4,400 of them have been released in the wild. (By contrast, Korth Lollar makes around 2,500 revolvers a year.) Barring a major investment by Beretta subsidizing a great increase in production capacity, I do not expect significant discounts from the MSRP.
