Can't blacken the PTFE containing finish, so this one's built in lubrication is hexagonal boron nitride. Same nickel-tungsten base coat for wear/corrosion resistance, but with a nickel-moly top coat w/ HBN for looks. The molybdenum was picked over the tungsten because it give a richer black.
Will heat treat tonight, and blacken tomorrow.
Everyone who sent in a mag will have this finish (they were done in the same batch as the Salient pistol).
