The SIG Sauer M400 Tread V2 Pistol (PM400-11B-TRD-V2) represents the apex of compact AR-15 platform engineering, delivering uncompromising duty-grade performance in a highly maneuverable, lightweight package. Building upon the legendary, accessible foundation of the original Tread series, the V2 introduces critical enhancements directly inspired by feedback from tactical professionals, competitive shooters, and law enforcement end-users, ensuring that out of the box, this firearm requires absolutely zero compromises.
At the mechanical heart of the PM400-11B-TRD-V2 is a premium 11.5-inch cold hammer-forged steel barrel chambered in 5.56x45mm NATO. Ballistically, the 11.5-inch profile is widely regarded by master armorers as the absolute sweet spot for compact 5.56 direct impingement platforms. It provides a vital 40% increase in gas system dwell time compared to standard 10.5-inch barrels. This mathematically optimized gas system translates to significantly reduced bolt carrier velocity, a remarkably smoother recoil impulse, and drastically improved extractor longevity—especially when running the system suppressed. The cold hammer-forged bore guarantees exceptional lifespan and heat resistance, while the precision-machined 1:7 twist rate offers flawless gyroscopic stabilization for heavy 62-grain penetrator and 77-grain MatchKing defensive loads. The muzzle terminates in industry-standard 1/2x28 threads, factory-fitted with a 3-prong flash hider, making it instantly ready to host your preferred suppressor or compensator.
The V2 upgrade introduces an entirely redesigned, free-floating Tread Enhanced M-LOK handguard. Engineered for maximum thermal mitigation and extreme weight reduction, this rigid alloy rail provides uninterrupted, full-length modularity for tactical white lights, infrared laser aiming devices, and hand-stops. The skeletal design maximizes convective airflow, completely resolving the overheating issues associated with legacy, restricted-ventilation designs during rapid strings of fire.
Fire control is expertly managed by the exceptional SIG Matchlite Duo 2-Stage Flat Blade trigger. This drop-in grade component delivers a clean, smooth initial take-up followed by a highly predictable break, dramatically enhancing user control and hit probability during rapid target acquisition. Fully ambidextrous safety selectors and an ambidextrous magazine release ensure seamless, intuitive operation regardless of dominant hand, environmental constraints, or complex barricade positioning.
Whether you are seeking an ultra-reliable platform for home defense, a compact and capable vehicle gun, or the perfect foundation for a customized tactical build utilizing the seamlessly integrated, universally compatible family of Tread accessories, the SIG M400 Tread V2 Pistol stands ready for deployment.
