I’ve been attempting to track down a new FNH FNP 45 with the matte black stainless slide. Item numbers 47911 for night sights or 47917 for standard white dot are what I'm looking for. I have thus far been unsuccessful and have only found the two tone stainless slide versions (47915) . I'm determined to wait for the black slide. Are the 45ACPs with matte black slides really so hard to find?
