Extensively tested, the Gen3 APL Glock’s concentrated, high-intensity tight beam fills your field of view for close to mid-range target identification. Now with 400 lumens of vibrant white light and weighing less than 3 ounces, it provides up to 1.5 hours of runtime. The water-resistant, glass reinforced polymer body is incredibly powerful yet compact in size. Integrating seamlessly with Glock rails, it offers constant and momentary operating modes. Textured paddles for a non-slip grip and ambidextrous on/off switches enable left or right hand activation. In addition, the easy-to-operate lockout system ensures the light isn’t activated until you’re ready.
