Crimson trace full size Green laser grip. I had it on my Glock 45, it works very well. Im selling it as no longer carry a Glock for duty.

Fits compact or full size Glock Gen 3-4-5

The green laser is far superior to red in daylight and at night -wow. I have crimson trace red laser grips on a 1911 and its no comparison in being able to see the green dot much easier in daylight.
