The SureFire X300U-A Ultra is the benchmark 1000-lumen pistol weapon light — a wide, far-reaching beam (11,300 candela) from a compact, bombproof aerospace-aluminium body that mounts securely to full-size and many compact handguns.
Its Rail-Lock system clamps to the rail without putting hands forward of the muzzle, and the ambidextrous toggle switches give intuitive momentary and constant-on activation.
Finish: Black — also available in Tan.
How It Compares
