The Streamlight TLR-3X, part number 59104, is the compact rail-mounted pistol light made specifically for the SIG Sauer P365 and P365 XL closed rail.
Dedicated fitment rather than a universal clamp. Nothing to shim, nothing to pack out, and no key to lose — it is machined for one rail and sits on it properly.
It measures 2.75 in and weighs 2.15 oz, producing 500 lumens with 6,500 candela for a 161 metre beam, from a body rated IPX7 to a metre for thirty minutes. Power is multi-fuel: one CR123A lithium primary cell is supplied, and Streamlight's SL-B9 USB-C rechargeable pack will run it instead if you would rather recharge than replace. Runtime is 1.5 hours on the CR123A or 1 hour on the SL-B9. Ambidextrous paddles handle activation from either side.
On a slim carry-sized pistol the weight hanging under the frame is what you notice first, and at 2.15 oz this is deliberately light for the output it gives. The important caveat is fitment: this part number is for the P365 and P365 XL closed rail only. The P365-XMACRO carries a 1913-style rail and takes the 1913 version of the same light instead, so match the part number to the pistol rather than to the family name.

What the TLR-3X fits
It is cut for the SIG Sauer P365 and P365 XL closed rail and nothing else. For a standard MIL-STD-1913 rail take the TLR-3X 1913 Rail, for a slim 1913 rail the TLR-3X 1913 Slim Rail, and the same P365 fitment supplied with the rechargeable pack is the TLR-3X USB SIG P365.
