The Viridian REACTOR RTL Gen 2 tactical light sighting system for the Ruger® LC9/380 This tactical light is easy to install and blends seamlessly into the trigger guard for invisible profile and smooth draw. The powerful 140 lumen tactical light has 2 modes: constant and strobe, with up to 2 hours of battery life. > The RADIANCE® taclight technology gives you a wider beam of light, illuminating over twice the horizontal area. With no wasted light above or below your target area, you get a better picture, faster discovery, smoother tracking and more positive targeting than any other weapon-mounted tool. The new gen 2 models feature a new INSTANT-ON ambidextrous, inside the waistband (IWB), custom fit holster with automatic light activation the moment you draw. Made of microfiber, this holster is more comfortable and durable than the previous models. The INSTANT-ON activation ignites the light the moment you draw. No buttons, no squeezing, no doubt. When you draw, it's on.
