The Streamlight TLR-8 X G sub, part 69439, is a subcompact weapon light with a green aiming laser, cut for pistols carrying the 1913OS offset rail.
Rail patterns on subcompact pistols are not interchangeable, and this is the 1913OS version. Streamlight list it, fitted with the #4 key, as the one that goes on the SIG P365-XMACRO.
White output is 500 lumens at 5,000 candela for a 141-metre beam. The laser is green at 510-530 nm, rated Class 3R under 5 mW, which the eye picks up far more readily than red in daylight. The light is 2.51 in long and weighs 2.77 oz on a CR123A cell or 2.87 oz on an SL-B9 pack, and a mounting kit with key and multi-tool is supplied along with one CR123A lithium cell.
It is multi-fuel, so the CR123A in the box can be swapped for Streamlight's SL-B9 USB-C rechargeable pack: white runtime is an hour and a half on the primary or an hour on the pack, and the laser alone will run for up to eleven hours on either. Ambidextrous high and low rear paddles give momentary and constant-on operation with a safe-off setting and a strobe the user can enable or leave switched out. The light selects white, laser, or both together.

What the TLR-8 X G sub fits
This one is rail-specific: it is built for the 1913OS offset pattern, and Streamlight are explicit that the P365 and P365 XL versions do not fit the XMACRO while the 1913OS models with the #4 key do. Other fitments in the same family are the P365 and P365 XL version and the 1913 short rail version, and the same light with a red laser is part 69419.
