SureFire XSC-B Handgun Light for S&W Sub-Compact - 350 Lumens, 90m Beam, Black Anodized Aluminum
Surefire
The SureFire X300T-A Turbo is a 650 lumen handgun light built for shooters who need serious reach and reliability mounted to their pistol. This compact weapon light combines a high-intensity beam with thoughtful design—66,000 candela of focused output throws light across the range while maintaining useful peripheral illumination for situational awareness. Whether you're running a defensive pistol, training on the range, or maintaining readiness at home, the X300T-A delivers the kind of light output that lets you identify targets and threats at distance, not just point-blank range.
The X300T-A mounts via SureFire's Rail-Lock system, which works with both Universal and Picatinny rails found on most modern handguns. The attachment is rock-solid and can be removed and remounted quickly without tools. The body is aerospace-grade aluminum with Mil-Spec hard anodizing—tough enough for duty use and rugged enough to live in a duty holster. It's sealed against the elements to IPX7 waterproof standard, so rain or sweat won't compromise it. The light is compact and dimensionally identical to the X300U, meaning existing X300U holsters will work with it.
Activation is straightforward: ambidextrous switches at the rear give you momentary-on with a press (either side) or constant-on by flipping up or down. That rear-mounted control works well if you're holding the gun in a ready position. If you prefer not to move your grip, SureFire makes optional DG grip switches that let you fire the light without changing your hand position—worth considering if you train regularly with a light-mounted gun.

The X300T-A Turbo produces 650 lumens with 66,000 candela output and a 514-meter beam. The two lights are dimensionally identical, so they share the same footprint and fit the same holsters. The main distinction is the T-A's superior light output and reach.
The X300T-A comes with ambidextrous rear switches that work with a press of your thumb. If you prefer not to adjust your grip at all, SureFire offers optional DG grip switches designed for pistols, which let you fire the light without changing your hand position.
Yes. The light meets IPX7 waterproof standards—it's sealed with O-rings and gaskets to protect internal components. It's rated for immersion in 1 meter of water for up to 30 minutes, making it reliable in rain, sweat, and duty conditions.
