Military Armament Corporation MAC 1911-9 Double Stack 9mm Black

The Military Armament Corporation MAC 1911-9 Double Stack is a modern 2011-style semi-automatic pistol designed in Knoxville, TN and precision-built by Tisas to exacting standards. Chambered in 9mm with a forged 4140 steel frame and slide, it features a factory RMR-pattern optic cut, M1913 accessory rail, and reinforced glass-filled polymer grip module for enhanced durability and control. The 4.25" bull barrel with hard chrome finish and 11° target crown minimizes recoil while maximizing accuracy in a compact, mission-ready package.

Key enhancements include a skeletonized trigger with approximately 4.75 lb pull for crisp breaks, removable aluminum magwell for rapid reloads, and aggressive 25 LPI checkering on front and back straps with textured polymer surfaces for secure handling. Ambidextrous thumb safety and grip safety provide intuitive operation, while the optics-ready slide with included plate adapter supports direct-mount red dots and lower 1/3 co-witness sights. Fiber optic front and serrated black rear sights ensure fast acquisition, with compatibility for a wide range of STI 2011 magazines.

Built for versatility across competitive shooting, everyday carry, home defense, and tactical applications, the MAC 1911-9 Double Stack delivers high 17+1 capacity, customizable optics support, and reliable function in a lightweight 30-ounce platform. Its potent yet controllable 9mm chambering, accessory rail, and premium included accessories make it an outstanding choice for shooters demanding modern performance in a classic double-stack 1911 design.
