Glock TAC03166 GTL 10 Tactical Light Handgun 70 Lumens Output White Xenon Bulb Black Polymer

The Glock TAC03166 GTL 10 is a purpose-built tactical light designed for duty use and defensive applications where reliable illumination can make the difference. Built on Glock's reputation for rugged functionality, this handgun-mounted light delivers 70 lumens of white Xenon output—enough to identify threats and navigate low-light environments without excess bulk. The polymer construction keeps weight down while resisting the wear and abuse of field use, making it equally at home on a duty pistol or a defensive carry gun.

What sets the GTL 10 apart is its simplicity and reliability under stress. The ergonomically-positioned soft switch offers intuitive activation without fumbling, and ambidextrous operation means both left and right-handed shooters can deploy it naturally. The Xenon bulb produces a focused beam with an effective range of 100 meters, and the optics are focusable so you can tailor the beam to your environment—whether you need a tight spot for distance or wider coverage for room clearing.

This light runs on two CR123A batteries, standard power sources you'll find in any decent gun shop or online retailer. At just 85 grams with batteries installed, it won't noticeably affect your pistol's balance or concealability. If you're building a serious duty or defensive setup and want a light that prioritizes function over features, the Glock GTL 10 delivers the no-nonsense illumination Glock users have come to expect.
