Laserguard green laser - Crimson Trace Laserguard Green Laser Sight for Springfield Full Size XD / XDM

Laser works good, easy to install, easy to use, laser is very bright. The only thing I don't like about it is, the laser extends past the end of the barrel. I installed it on a XDM 9mm Springfield, with a 3.8" barrel. The lens of the laser gets very dirty, very quickly and it will start dulling the brightness of the laser. Other than the few things I've mentioned, I'm satisfied with this laser.
