F.YI. U best look again at vendor if u r shopping for green laser. The green laser is the only way too go where even in slight cloudy days u can sight in 25 yards with no problem. Furthermore, I own a laser max that even fits on my compact gun and weight is very lite n unit itself is small enough not to protrude. Mind u that u get what u pay for n it don't come cheap unless u r a military man in service.I had looked at one of the green laser sights on one site, and they suprisingly are not that high.
