SureFire X300U-B

Ultra-bright, battle-tested pistol light.
The SureFire X300U-B delivers a focused 1,000-lumen beam in a compact, hard-anodized aluminum body — engineered for law-enforcement, self-defense, and tactical use. Its T-slot clamp secures the light to Picatinny/1913 rails without altering grip, while ambidextrous switching and optional remote/tape switches let you control illumination without changing hand position.
