Delivering 650 lumens for up to two hours courtesy of a single CR123A battery, the TCM-35 Compact Weapon-Mounted Light for Sig Sauer P365 series pistols from Nightstick features a total internal reflection lens that projects an LED light up to 446' in a focused and intense beam. This concentrated light forms a tight bright spot, allowing for swift threat identification and confirmation, and is contoured with a defined outer halo that provides valuable situational feedback. The TCM-10 works in momentary or constant-on flashlight modes, toggled with ambidextrous rear-facing switches, enabling precise control over lighting conditions. Users may also program a strobe mode or activate the battery-safe mode as needed.
