According to the collectors that know, They say the new Chapuis MR73 are made on equipment like the old Mulhouse guns. I had two of the current Chapuis guns but sold them due to the end shake. I am not trying to dissuade you from buying one as they are very very fine revolvers with a beautiful finish but I prefer the new Lollar Korth to them. I am sure the amount of endhake on the MR73 is within spec but I did not like it.
