Electroless nickle in a satin finish is not really 'french gray' but remember it has come to be a 'look' rather than a process.. Nickle finished firearms are most deffinately not a new thing.. If properly done they will last a long time. Nickle is a fairly soft metal and I would suspect the satin finish will polish on the edges and where one normally finds holster wear. Also if not properly applied it can peel, although I would suspect MR. Brown knows quite well what he is doing... Good luck from the gunnut69
