BudsGunShop.com - Max effective distance of laser?

Derek, the Red laser will be about 40yds on a non bright day and 15yds on a bright sunny day. I would highly recommend getting the Green Laser version for superior performance in all conditions.

40 yards or so indoors outside mine is good to about 10 yards

Derek, How far would your target be at in a defensive protecting your life situation? That is the effective range of a laser. Any further then that the laser is a toy. With that being said a rail-mounted laser will shine on the target within about 3 inches of your point-of-impact (POI) all the way out to around 50 yards, depending on your load, of course.

Derek, the Owner's Manual from Crimson Trace states the green laser is a 1/2 inch circle at 50 feet, but they don't give a maximum effective range beyond that.
