Viridian reactor 5 green laser sight - Viridian Reactor 5 Green Laser Sight for Smith & Wesson M&P Shield with ECR Hybrid Belt Holster

Received the Viridian 5 Reactor Green Laser Sight and installed it on my S&W Shield 40. I was able to sight it in using the iron sights but haven't been to the range yet. Everything was straight forward. This unit appears to be a quality piece. Time will tell how reliable it will be.

The laser came with an OWB "ECR" holster which has an option to turn on automatically when the weapon is drawn. This, for me and most users, will be a necessity as the small power button is on the right side and would be difficult to activate under stress.

Hope this helps.
