The Bayco Nightstick TCM-365 is a subcompact weapon-mounted light engineered specifically for Sig Sauer P365-series pistols, including the P365 X, XL, SAS, and other variants in the lineup. If you carry a P365 for personal defense or duty, this light solves the real problem: identifying threats in low light without fumbling for a separate handheld. At 650 lumens, it delivers enough output to illuminate a room or outdoor threat at meaningful distance—the focused beam reaches 136 meters for confident threat identification. Bayco designed the rail clamp to work with the P365's distinctive side-slot mounting system, so it clamps securely without the universal-fit looseness that plagues generic solutions.

The light runs on a single CR123 battery (included) and employs an engineered TIR lens that throws a tight, bright central spot for aiming and identification, surrounded by a crisp outer halo that gives you situational awareness without blinding you to movement at the edges. The rear-facing toggle switches are completely ambidextrous—operate them from either side of the light with your thumb or trigger finger, depending on your grip. You get momentary-on for quick target checks and constant-on for sustained illumination, plus user-programmable strobe and battery-safe modes if you need them.

Built from aircraft-grade 6061-T6 aluminum with a Type III hard-anodized finish and polymer rear housing, this light is engineered to survive carry and use. It's waterproof, impact-resistant, and chemical-resistant—the kind of durability you expect when a light shares holster space with a defensive firearm. The light comes serialized for personal ID. Whether you're training at the range, carrying for home defense, or running low-light drills, the TCM-365 keeps your hands on the gun and your target illuminated.
