Melonite is not a finish, its a treatment to the metal itself.gotta tell ya ,i put both styles together in hand and compared. the black slide is what i wanted till i seen it. it has that cheap ,no wear chalky look. like sigs . looks as if it will rub off in a month. i did not hesitate to go with the stainless. it's much nicer. it's a flat tone stainless that will last a long time and still look newq. i'll take a all black gun anytime over a two tone but not this time. the melonite is garbage.
