I already use a laser sight and I love it. For daylight conditions I would recommend open sights and alot of practice. But for indoor, low light, half awake situations I'd choose a Laser handsdown anyday. That with a tactful flashlight. But my question wasn'tshould I use one or not but rather what makes a green laser better. I know that the human eyerecognisesthe yellow/green color best, but is there more to it? In addition how do they get a Green laser in a 635 nm wavelength? As far as I know thats in the red spectrum range. Green is in the 520nm to 565 nm Range
