The Streamlight TLR-3X USB 1913 Slim is a compact, rail-mounted weapon light configured for select slim-frame compact and subcompact handguns. This black model delivers 500 lumens and 6,500 candela through a concentrated beam that reaches 161 meters while still providing useful peripheral illumination. The included Streamlight SL-B9 lithium-ion battery pack supports convenient USB-C recharging and supplies one hour of continuous operation. The light also accepts a single CR123A lithium battery, giving users a readily available backup power option with a rated runtime of 1.5 hours. Its 1913 Slim mounting configuration is designed for the Glock 43X MOS, 48 MOS, 43X Rail and 48 Rail, as well as the FN Reflex and Reflex XL. A snap-on-and-tighten interface allows the light to be installed or removed without placing a hand in front of the muzzle, while battery access through the face cap eliminates the need to remove the light when changing power sources. Rear switches positioned on both sides support ambidextrous activation, with momentary, constant-on and user-activated strobe functions available. Multiple paddle sizes are supplied so the switch arrangement can be adapted to the handgun and the shooter's preferred grip. The housing is constructed from impact- and chemical-resistant, heat-stabilized engineered polymer, and the high-temperature BOROFLOAT glass lens is shock mounted for impact and scratch resistance. An IPX7 rating allows the light to withstand immersion in one meter of water for up to 30 minutes. Measuring 2.75 inches long, 1.07 inches wide and 1.29 inches high, the TLR-3X maintains a narrow profile and weighs 2.25 ounces with the included SL-B9 battery installed. The package also includes the appropriate mounting key, interchangeable paddles and a multi-tool for installation and switch changes.Specifications and Features: 500 lumens, 6,500 candela and 161-meter beam distance 1913 Slim rail configuration Fits Glock 43X MOS, 48 MOS, 43X Rail and 48 Rail; FN Reflex and Reflex XL Includes SL-B9 USB-C rechargeable battery; also accepts one CR123A Runtime: 1 hour with SL-B9 or 1.5 hours with CR123A Momentary, constant-on and user-activated strobe modes Ambidextrous rear switches with interchangeable paddles Impact and chemical-resistant engineered polymer body IPX7 waterproof to 1 meter for 30 minutes Size: 2.75 x 1.07 x 1.29 inches; 2.25 ounces with SL-B9 Includes mounting key, paddles and multi-tool Brand: Streamlight Series: TLR-3X USB Product Type: Weapon Light Manufacturer Part Number: 59103 UPC: 080926591035
