Great light/laser - Streamlight TLR-8A LED Weapon Light and Laser

This is the updated version where you actuate the buttons by pressing down rather than in toward the firearm. It's a more natural movement as opposed to the old style. The lumens is just enough to light up a room or disorienting a would be attacker. I like how it fits flush with the end of the barrel of my gen 5 glock 19. Highly recommend!
