The Trijicon Dual Defense™ Kit combines the legendary RMR® and the Suppressor/Optic Height 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 Suppressor/Optic Height 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 back up 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.



NOTE: Designed to be mounted to Glock ® MOS pistols, Sig Sauer optics ready pistols or custom optics cut guns. Professional installation is recommended. If mounting to Sig Sauer pistols additional mounts may be required, check our RMR accessories section for mount options.
