Keep It Simple. Lightweight and compact, the SureFire XC1 securely mounts to railed handguns without hampering concealability and delivers 300 lumens of white light from a single AAA battery. The proprietary MaxVision Beam reflector shapes the light into a wide, smooth beam pattern ideal for close-range ID. The XC1's intuitive, ambidextrous switching provides both momentary- and constant-on activation options. Its precision-machined aerospace aluminum body is Mil-Spec hard anodized and sealed to repel the elements. As a result, it's plenty rugged enough for everyday carry and light enough that it won't weigh you down.
