Like many here, I can't leave things alone. I got a wild hair for a two-tone revolver and off to H&M Black Nitriding my 627 went for a completely unnecessary makeover - I also sent my Delta Elite's barrel and bushing. This stuff is good looking and EXTREMELY durable. I believe it has a Rockwell hardness of 70 and penetrates 5 mills.
My buddy's 15 has had its cylinder cycled several thousand times and there's still no discernible turn line.
