Great laser - OpticsPlanet Exclusive Crimson Trace Defender Series DS-125 Universal Laser Sight

I rated a three because I bought two. One for a Glock 17 and one for a Ruger P95. It fit the Glock just fine. The Ruger, it barely fit over the rail and I couldn't get the mounting screw to thread because the screw is really short. I had to sand down the mounting points on the laser so that the. Screw would go through and tighten the laser to the gun. But it's on now. Laser is nice and crisp.
