Designed specifically for 1-handed shooting with rail-equipped Glock® Gen 4 & Gen 5 handguns, the Streamlight® TLR-7 69428 with Integrated Contour Remote features a snag-free profile for smooth holstering. The single, high-efficiency LED bulb delivers an impressive 500-lumen maximum output, illuminating targets out to 131 meters, while the durable, precision-machined, anodized aircraft aluminum housing easily shrugs off punishing recoil. Ambidextrous, grip-controlled pressure switch readily accommodates right- and left-handed SWAT operators, K9 handlers, door breachers, and other close-quarters operators. The rail grip clamp system quickly and securely attaches/detaches to your pistol’s accessory rail, without requiring any special tools or putting your hands in front of the muzzle. Operating on a single CR123A lithium battery (included), the Streamlight TLR-7A boasts a 1.5-hour battery life. Plus, a “Safe Off” feature prevents accidental activation during carry, storage, or holstering. IPX7 waterproof.
