MAC-5 9mm 8.9" Threaded Barrel 30rd Pistol W/ Tri-Lug Muzzle Device

Introducing the MAC-5 Pistol 9mm—a modern evolution of the iconic roller-delayed blowback platform, faithfully crafted with precision, affordability, and compatibility in mind. Built on original HK specifications and backed by decades of firearms expertise, the MAC-5 captures the legendary performance of the MP5 in a streamlined, user-friendly pistol ideal for defense, competition, and collectors alike.

Its tri-lug muzzle device and standard 5/8x24 threading make suppressor attachment fast and secure. Ergonomics meet durability with a reinforced polymer grip, while the SEF-pattern trigger offers a crisp break around 4.25 lb.

Whether you're seeking trusted reliability, upgrade-ready compatibility, or timeless design, the MAC-5 delivers in every category. Fully HK- and MP5-compatible with aftermarket parts, and soon to be supported by a full line of MAC-branded accessories, it’s not just a pistol—it’s a commitment to excellence.
