Blackhawk! Law Enforcement and Night Ops have developed a holster that works with a pistol light. The SERPA Level 3 Duty Holster, noted for its speed and outstanding retention, is combined with the Night-Ops XiphosNT single-handed multi-functional pistol light with programming function capabilities. The XiphosNT is a 3-volt rail-mounted LED pistol light featuring a new patent-pending Cam-Clamp mount that allows the user to quickly install this light onto almost any open and closed rail weapon mount including picatinny, universal and other rail-mount designs. The pistol light features digitally controlled "smart" circuitry that has been programmed to perform several functions with ease, even under stressful conditions.
