Excellent light/laser green. - Crimson Trace CMR-207 Rail Master Pro Laser Sight & Tactical Light System

Very pleased with this purchase! Easy to operate and mounting was a breeze. Holds zero and easy to sight in, on a full size Glock model 22. Adjust the laser using tiny movements. I began by adjusting the laser to the sights on my pistol, then began shooting paper at 18 yards. Wherever the bullet hits, adjust towards that hole using tiny adjustments! It's easy to adjust too far so expect to be shooting 6-8 rounds. Once on target you're going to be pleased with how easy it is to follow up shots into a nice small group... if you are using a New firearm expect to make adjustments later on as there is usually a Break-In period you'll have to go through.
