Easy install, great product - Crimson Trace Laserguard Laser Sight for S&W Shield Handgun

This product was great to install and was almost dead accurate with zero adjustments right out of the package! Only reason I didn't rate it 5 stars is that I am still undecided about the auto on feature for both the light and laser. I don't like the idea of announcing my presence with the light before I am ready to fire, but realistically, I suppose it is probably better to not need to think about the switch if you ever really need the light.
