The World's Finest Subcompact Handgun WeaponLight. The XC3 Sub joins SureFire's XC3 family, providing the optimal weaponlight solution for subcompact concealed-carry handguns. It packs duty-grade durability and performance in an easily concealable form factor that securely fits most railed, subcompact handgun models. Powered by its included SFRCR123 rechargeable lithium battery, the XC3 Sub's LED generates 1,000 lumens of intense white light and 13,000 candela shaped by our precision-engineered parabolic reflector for positive target identification up to 228 meters in low-light environments. Additionally, the beam pattern delivers an optimized corona of diffused light for situational awareness in the near field. For added versatility, the XC3 can also be powered by a single 123A lithium primary battery. Intuitive, ambidextrous switching provides both momentary and constant-on activation options. We've constructed the XC3 Sub's robust body from lightweight, high-strength aerospace aluminum, then Mil-Spec hard anodized and sealed it to repel the elements. As a result, the XC3 Sub is compact yet rugged enough for everyday use without weighing down your handgun. Features: High-performance LED produces 1,000 lumens and 13,000 candela for positive I.D. in low-light environments Hybrid beam pattern creates a smooth, far-reaching beam with a center spot that's highly effective for close- to medium-range engagements Included rail clamp mount (and SureFire accessory mounts sold separately) facilitates secure attachment to a variety of subcompact handgun models Front-loading battery port (behind bezel) offers quick and easy battery changes Dual Fuel: Generates 550 lumens and 7,200 candela when powered by a single SF123A lithium primary battery Integral ambidextrous momentary- and constant-on switching provides easy, instant activation Disable feature prevents accidental activation when in storage or traveling High-strength aerospace aluminum body is Mil-Spec hard anodized for extreme durability
