SIG Sauer M400 Sdi 556 5.56 NATO 11.5" 30-Round Threaded Barrel Pistol

The SIG Sauer M400 SDI 556 5.56 NATO 11.5" threaded barrel pistol is a modern, compact alternative to traditional rifle platforms, designed for tactical professionals and civilian shooters who prioritize maneuverability without sacrificing effective range. This versatile pistol is ideal for home defense, vehicle-mounted roles, or close-quarters tactical operations where space is limited.

Built on the proven M400 platform, the 11.5" barrel length offers an optimal balance between velocity retention and handling. The threaded muzzle allows for immediate suppressor compatibility, enhancing sound signature reduction in critical scenarios. Engineered with a free-floating barrel assembly and precision machining, the M400 SDI is designed to deliver consistent sub-MOA accuracy even during rapid-fire sequences.

With a 30-round magazine capacity, this pistol provides ample ammunition for extended engagements without the need for mid-combat reloads. The 5.56 NATO chambering ensures access to widely available and cost-effective ammunition, while the black anodized finish protects against corrosion and wear. Its modular design allows for easy integration of rail-mounted optics, lights, and accessories, making it a reliable choice for law enforcement and military tactical units.
