The Viridian R5 Gen 2 green laser sighting system for the Springfield® XD-S and XD-S mod 2 9/40/45. This laser sight is easy to install and blends seamlessly into the trigger guard for invisible profile and smooth draw. Viridians green lasers utilize a 510-532nm wavelength range creating an optimum target dot that is up to 50 times brighter than red lasers. It features two modes of operation: constant and strobe. New features of the gen 2 models include 3X more battery life (up to 5 hours) and an INSTANT-ON ambidextrous, inside the waistband (IWB) holster with automatic laser activation.
