Is anyone here using a Viridian Reactor 5 gen 2 green laser ? I have a friend that has a older Viridian red laser that came with her Sig p238 she has me change the batteries in it about every 12 months and she says it works great. I like the idea of a green laser that turns on and off when you draw and holster your pistol. About all I know about them is you need a magnet on your holster to make them work.
