The SureFire X400T handgun light and laser combo brings serious versatility to your carry or duty pistol. This compact mounted light combines 500 lumens of white LED output with a green laser, giving you multiple ways to acquire and engage your target—whether you're working in daylight, darkness, or low-light conditions. The green laser is particularly useful for quick target designation without breaking your sight picture, while the high-intensity beam from the parabolic reflector handles medium to long-distance illumination. Built on an aerospace-grade aluminum frame with Mil-Spec hard anodizing, the X400T is sealed to IPX4 weatherproof standards, so it'll keep working in rain, dust, and the elements you encounter in the field.
Control is intuitive and ambidextrous—you get momentary and constant-on switching at the rear of the body for one-finger operation from either side. A mode selector lets you run light only, laser only, or both together, adapting to whatever your situation demands. The T-slot thumbscrew clamp locks down securely to Universal and Picatinny rails found on most modern handguns. If you want to refine your activation even further, the X400T accepts optional pressure-activated remote switches (DG grip switches for pistols, XT07 tape switch for long guns) so you can fire the light or laser without changing your grip on the weapon.
The green laser is Nylok-adjusted to resist backing out under recoil, so once you zero it, it stays put. Whether you're training at the range, building a home-defense carbine, or equipping a service or duty weapon, the X400T gives you the optical flexibility and rugged reliability SureFire is known for.
