The TCM-365 Subcompact Weapon-Mounted Light for the Sig Sauer P365-Series produces 650 lumens from a single CR123 battery. Its unique rail clamp is designed specifically for the unique side slots on the P365 model pistols, which include the X, XL, SAS, 380, and XL Spectre Comp. An engineered TIR lens projects a tight bright spot for threat identification and confirmation that reaches 136 meters. The lens also produces a crisply defined outer halo for additional situational feedback.
