The Streamlight TLR-3X USB, part 59103, is a compact rail-mounted pistol light built for the 1913 Slim rail and supplied with an SL-B9 USB-C rechargeable battery pack.
This is the rechargeable package of the TLR-3X, and it is cut for the narrower 1913 Slim rail rather than the standard one — the fitment is the first thing to check, not the last.
It produces 500 lumens and 6,500 candela for a 161 metre beam from a body 2.75 in long weighing around 2.25 oz, rated IPX7 for a metre of immersion for thirty minutes. Ambidextrous paddles work it from either side. The SL-B9 pack charges over USB-C in about two and a half hours, in or out of the light, and the light is multi-fuel, so a CR123A lithium primary can be dropped in instead.
Runtime is one hour on the SL-B9 pack or an hour and a half on a CR123A cell, so the rechargeable pack buys convenience rather than endurance. Streamlight's fact sheet gives the 1913 Slim fitment as covering the Glock 43X/48 MOS, the Glock 43X/48 Rail, and the FN Reflex and Reflex XL. One thing that is not in the box: Streamlight sells the USB-C charging cord as an optional accessory, so use a cable you already own or order one alongside.
It is cut for the 1913 Slim rail found on slim-frame pistols, so check the rail on yours before ordering. The same light for a standard 1913 rail is the TLR-3X USB 1913, the version supplied with a CR123A cell instead of the pack is the TLR-3X 1913 Slim, and other rechargeable options sit in rechargeable weapon lights.
