Viridian Reactor R5-R GEN 2 Red laser sight For SIG P365 with IWB Holster. The Viridian REACTOR R5-R Gen 2 red laser sighting system. This laser sight is easy to install and blends seamlessly into the trigger guard for invisible profile and smooth draw. Viridians red lasers utilize a 635-650nm laser wavelength to generate the brightest, sharpest red dot possible. The gen 2 models feature an ambidextrous, inside the waistband (IWB), custom fit holster with INSTANT-ON activation. Made of microfiber, this holster is more comfortable and durable than the previous models. The INSTANT-ON activation ignites the tactical light the moment you draw. No buttons, no squeezing, no doubt. When you draw, it’s on. &#####x200B;&#####x200B;&#####x200B;&#####x200B;&#####x200B;&#####x200B;&#####x200B.
