I have one that I had Jack Fusilier nickel plate in a matte finish. I had a mak that had marks, poor finish on the slide, didn't want to go through the hassle of sending the whole pistol (FFL issue), and think that the tu-tone looks great. He did a great job and everything cost me less than 50 bucks I believe.
I forgot to mention that originally I wanted a shiny finish and talked with Jack about it. It would have required metal work because my slide was worn and dinged a bit. He told me he prefered the matte finsih because it is the most practical for a carry piece. I am very pleased with his suggetion--the marks do not show unless you really look closely--even the ding on the sight rail on the other side.
