SIG SAUER M400 SDI PISTOL Features
The SIG SAUER M400 SDI PISTOL is a compact 5.56 NATO platform engineered for durability, modularity, and responsive handling. Built around an aluminum receiver set with a black anodized finish, it is designed to withstand demanding use while maintaining corrosion resistance. The 11.5-inch barrel configuration balances maneuverability with effective ballistic performance, making it well suited for close-quarters or range applications. Its semi-automatic operating system follows the proven AR-pattern architecture for consistent cycling and familiarity.
An M-LOK handguard provides flexible mounting options for lights, grips, and other accessories without unnecessary bulk. The flat-top, optic-ready upper receiver allows direct installation of compatible optics to enhance target acquisition. A folding pistol brace improves stability and transportability while preserving compact dimensions. The control layout mirrors standard AR ergonomics, supporting intuitive manipulation and straightforward maintenance. Supplied with a 30-round magazine, this configuration offers practical capacity within a streamlined, adaptable platform.
