I got a Viridian CL5 laser/light/strobe combination and like mine. Have it zeroed in at about 5 yards(15 feet) .. have it set for strobe light and laser .. Have it attached to my bedroom gun, I went with it instead of a separate light that would have to be held in the off hand.
Just remember that what ever distance you zero in to POA that inside of that range the shot will be above where the laser points and anything further beyond your zero point will be below the laser point.
At 3 feet mine would shoot about 3-4 inches higher then where the laser is pointing. Just have to remember that if your ever in a SD shooting and use it .
