I have no experience with green lasers, other than a friend of mine is an astronomy buff. With the green laser you can actually see the beam of light from the laser out for a long ways. He brings his on camping trips and uses it to point out stars, constellations,etc. With my red laser, the beam has to strike a surface for the dot to be seen. I'm thinking that with the beam visible from the gun out, you should be able to get on target faster. Just a hunch.
