The SureFire XC3-A delivers duty-grade durability and performance in a lightweight, compact form factor that securely fits most railed, compact handgun models. Powered by a single 123A lithium battery, it generates 550 lumens of white light output, and its proprietary, precision-engineered smooth parabolic reflector projects an intense beam with a focused hot spot for short-to-mid-range illumination. Additionally, the beam pattern provides an optimized corona of diffused light for situational awareness in the near field. Intuitive, ambidextrous switching provides both momentary- and constant-on activation options. We've constructed the XC3-A's robust, compact body of lightweight, strong aerospace aluminum, then Mil-Spec hard anodized and sealed it to repel the elements. As a result, it's rugged enough for everyday carry without weighing down your handgun.Lightweight and ultra-compact; great for concealed carryRail clamp mount securely attaches to most Universal andPicatinny accessory railsPowered by one 123A lithium battery which is loaded in thefront of the XC3-AIntegrated ambidextrous momentary and constant-on switchingQuickly tap and release either toggle switch for constant onactivation; to turn off, simply tap and release either toggle.Press and hold either toggle switch for momentary activationand release to turn offDisable feature to prevent accidental activation while instorage or traveling.Mil-Spec hard-anodized aluminum body and tempered windowmake it light rugged and durable
