The Streamlight TLR-3X, part number 59100, is a compact rail-mounted pistol light cut for standard MIL-STD-1913 rails, supplied with a mounting kit and one CR123A lithium cell.
Two and a bit ounces, under three inches long, and still 500 lumens with 6,500 candela behind it. This is the light you fit when you do not want to feel it on the frame.
It measures 2.75 in and weighs 2.15 oz with a CR123A fitted or 2.25 oz with an SL-B9 pack, and it is rated IPX7 for one metre over thirty minutes. Switching is by ambidextrous paddles either side of the body. Output is 500 lumens and 6,500 candela for a 161 metre beam, running 1.5 hours on the CR123A lithium cell supplied or 1 hour on Streamlight's SL-B9 USB-C rechargeable pack.
Multi-fuel is the practical feature here: the light arrives with a primary cell that will sit in a drawer for years without losing charge, and the same body takes a rechargeable pack if you would rather plug it in than buy cells. The constraint is the rail. This part number is cut for a full-width MIL-STD-1913 rail, so a slim-rail frame or a dedicated sub-compact pattern needs the version made for it.

What the TLR-3X fits
It fits handguns and rail-equipped platforms carrying a standard MIL-STD-1913 rail. For a slim rail, the TLR-3X for 1913 Slim rails is the same light on a narrower fitment, and for the SIG P365 series see the TLR-3X for the SIG P365. If you would rather have the rechargeable pack in the box, the TLR-3X USB for 1913 rails is the same light in the other battery package.
