M&p shield - Viridian Reactor 5 Green Laser Sight for Smith & Wesson M&P Shield with ECR Hybrid Belt Holster

Beware. Nowhere on this site does it tell you this site WILL NOT work on the new .45 Shield. Viridian says they won't have one available for it least a year. IT did work on a friend's 9mm M&P Shield. I also do not like the power on button. If you have fat fingers the switch is indented to far to power it on quickly. I will not by another one.
