Nighthawk Custom Sight Kit Gold .190 Heinie Ledge Black Rear Sight Novak Cut. The Heinie Ledge rear sight design utilizes a .125 rear notch width. The rear face of the sight is serrated and a smooth front leading up to the ledge clear of any snag points for easy carry. The serrations on the rear of the sight eliminate glare from light sources while aiming. This solid black Heinie Ledge is designed to help shooters rack the slide with a single hand. This rear sight requires machining of the slide for installation. Heinie recommends having a competent pistolsmith install these sights. The Nighthawk Custom gold bead front sight uses a 14K solid gold not plated insert to draw the eye to the front sight while retaining a low snag-free profile. Aside from the increased sight acquisition in daylight shooting the gold bead also adds a bit of class to the look of your 1911.
