Compact, high-intensity incandescent flashlight for duty and tactical use or conditions requiring enhanced grip. Similar to our C2 but a slightly longer,more powerful three-battery version. Patented, ergonomic rubber grip ring allows the light to be operated with a handgun, using the SureFire technique. Puts out a smooth, brilliant, pre-focused, tactical-level beam with over five times the light of a big two-D-cell flashlightâbright enough to temporarily blind and disorient a person by impairing his night-adapted vision. Light output may be nearly doubled with optional P91 lamp.
