The Trijicon Dual Defense Kit combines the legendary RMR and the industry-leading Bright & Tough Night Sight set into one, easy-to-use kit. This new kit adds speed and precision to your self-defense, law enforcement, military, competition, or target pistol. The Bright & Tough night sights are engineered to the optimal height so that the iron sight can be seen through the optic lens. Having co-witnessed iron sights helps you quickly acquire the red dot, and if necessary, provides a backup aiming solution. The Dual Defense Kit is now available for the six most popular GLOCK and SIG Sauer handguns, making it easier than ever to upgrade your pistol with everything you need in one kit.
