I have a Glock Tactical Light in excellent condition with all the original stuff that it came with. I purchased it new 5 months ago and it sat in my nightstand safe on a Glock 23 the entire time. I only ever used it to sight it in. It is the light and laser model with the optional dimming light. There are three modes: light, laser, or both. Plus, you can chose to have the light come on full power or a gradual dim light to full power. I have a variety of Surefire and Streamlight light laser combos and this is by far my favorite. The model number is GTL-22 but I have also seen it listed as TAC4065. $200
