The TSM-13G Subcompact Tactical Weapon-Mounted Light with Green Laser for all Sig Sauer P365 pistols (X/XL/SAS) uses a super-bright LED rated at 150 lumens working in conjunction with a precision-engineered miniature reflector to create a bright white beam of light rated at 104 meters. This weapon light features ambidextrous low-profile switches on each side of the light to operate the momentary-on and constant-on lighting modes or Class IIIa 532nm daylight-visible green laser. These lighting modes include white light, laser, or both light and laser.

The two glass-filled nylon plastic housings of the TSM-13G is designed to lock onto the front of the pistol's trigger guard for secure installation and the lowest profile possible. The weapon light includes a Nightstick MagMate USB magnetically coupled charger, a trigger lock for secure charging, and an Allen screwdriver for installation and laser aim adjustments.
