Any one using a laser on there M&P? I've been looking for a green laser, as for me it's been the easiest to see when I've used them on other guns compared to the red lasers, but I can't seem to find one that I like. I really like the S&W M&P laser, but not too happy bout having to pay over $250 for one. I'd really like to have one that will mount on the picatinny rail with out the cord to turn it on/off. Any ideas???
