Viridian Weapon Technologies Reactor 5 G2, Red Laser, Fits M&P Shield, Black Finish, Features ECR INSTANT-ON, Includes Ambidextrous IWB Holster 920-0013

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. Viridian's red lasers utilize a 635-650nm laser wavelength to generate the brightest, sharpest red dot possible. These lasers feature 2 modes of operation (constant and strobe) and up to 12 hours battery life. The new gen 2 models feature a new 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.
