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

I bought this for my wifes M&P Shield. This is a very good laser and is worth the money. The fact that it is green really helps to see it in daylight compared to the red lasers. Assembly was easy and straight forward. I like some other reviewers would have preferred that you did not have to remove the laser from the pistol to change the batteries and that the power button was a little easier to turn on and off. All in all this laser is a good one and would not hesitate to purchase another one.
