Good luck with this. It does NOT ship with any instructions or a guide. Was eventually able to put it on my Beretta PX4 and dial it in. I inadvertently backed out the windage screw alltogether, and it was a #$@*$ to get back in. Once I did, I was able to dial it in. There's another rail mounted on the bottom of this to add more bling to the gun. However, you don't want to remove the second rail, the end of the elevation screw will be exposed. Light is bright in a darkened room., haven't tested it in daylight yet. Also haven't fired the weapon with the laser on it, so I don't know if it will handle the recoil. In the box: Laser 3 batteries 3 allen wrenches of different sizes. The most important (windage & elevation) is VERY SMALL - don't lose or break!
