I searched and found some info online, centerfire had these listed for a minute as MR73 and at $1300.00 I believe, someone contacted them and said "are you sure them aren't MR88's ?" So they pulled them for a couple of weeks and then relisted. I'm a sucker for a shiny 3" revolver but dang $700.00 used is making me nervous LOL.
Found the below in a article.
Like Korth Combat revolvers, Manurhin revolvers are the stuff of legends, specifically the MR73. The Manurhin factory museum has an MR73 used by the GIGN (the elite police tactical unit of the French National Gendarmerie) on exhibit that has a round count of 96,000 full-power .357 Magnum. This round count is only rivaled by Korth revolvers (and properly built pre-1972 Colt Pythons).
Manurhins aren’t as expensive as Korths though, which is why among the really passionate (and rich) revolver enthusiasts, Korths might be considered the best revolvers in the world but Manurhins are considered the best practical revolvers in the world.
Designed and developed by Chapuis Armes of France, these revolvers are robustly built and guaranteed to be pinpoint accurate out to 25 meters. The specific model we recommend, the stainless MR88, is a 6-shot revolver with a frame and cylinder release that resemble those of Ruger GP100 revolvers (because they purchased the rights to use Ruger’s proprietary investment casting process).
The MR88 is available in 3-inch, 4-inch, 5.25-inch and 6-inch barrel configurations. There is no pricing data available from the manufacturer’s website but I recently emailed them and got a reply from a gentleman named Pierre Laurent. He informed me that the only US importer of these revolvers is Kebco LLC of Hanover, Pennsylvania.
I forwarded the inquiry to Kebco LLC and got a reply from another gentleman by the name of Ken Buch. He told me they will have some 6-inch MR88s available this coming summer and it costs $1,600. It will be delivered straight to my FFL and they’ll require a 50% deposit to reserve one for me.
Given the reputation of these Manurhins for strength and accuracy, I wouldn’t hesitate to shell out $1,600 if money wasn’t a concern (my wife would kill me if I did though, so sadly, no Manurhin for me).
