DeadRinger DR4449 Snake Eyes Tritium Front/Rear Ruger SR9/SR40/SR45 Green/Orange - The design of Dead Ringer's Snake Eyes pistol sights lends itself to the natural shooting position while allowing quick target acquisition with minimal learning curve. Snake Eyes is more than just a 3-dot sight set; the white dot front and ghost ring rear with Lexan light pipes glow even in low-light conditions. Snake Eyes sights are manufactured with 100% military grade metals, making them both durable and reliable. This front and rear sight combo fits Ruger SR9/SR40/SR45 handguns. Note: Rear Sight is a press fit application and should be done by a professional gun smith to avoid potential harm to slide or sight.
