Features
Engineered for versatility, this full-size, hammer-fired 9mm pistol features a factory RMR optic cut on the slide and a universal light rail, making it a solid choice for duty use, home defense, or competition. Its 5-inch bull barrel, finished with a QPQ Tenifer coating and an 11-degree target crown, helps reduce recoil while maximizing accuracy.
The MAC Duty 9 Double Stack is built with durability in mind, featuring a 4140 hammer-forged steel slide and frame with a rugged Cerakote finish. The polymer grip module provides a firm yet comfortable texture, and the skeletonized trigger — adjustable for overtravel — delivers a crisp 4.75 lb trigger pull.
A competition-grade aluminum magwell ensures smooth, fast reloads, while the fiber optic front sight and black serrated rear sight offer a clear sight picture. The pistol ships with two 17-round Checkmate magazines, an optics plate system, and a premium lockable hard case—all at an MSRP of $1,099.99.
