Maxim Defense MXM48172 CPS MD9 5.5" Carbine

The Maxim Defense MXM48172 CPS MD9 5.5" Carbine is a purpose-built platform designed for operators and tactical professionals who require compact firepower without sacrificing controllability. Chambered in 9mm Luger, this carbine effectively bridges the gap between duty pistols and full-size rifles, providing superior velocity, accuracy, and ergonomic control in confined spaces—making it ideal for vehicle operations, close-quarters training, and specialized law enforcement deployments.

Weighing 7.74 lbs, it remains manageable for extended carry while maintaining the rigidity necessary for precision shooting. The 5.5-inch barrel optimizes velocity and dwell time for reliable ammunition cycling across commercial and duty loads. The Maxim Defense CPS (Continuous Platform System) receiver ensures modularity for future customization and accessory integration.

This platform excels for law enforcement agencies, tactical teams, and civilian operators who standardize on 9mm ammunition for cost efficiency and logistics. The MD9 designation confirms this platform's 9mm optimization, meaning the bolt, magazines, and feeding geometry are engineered specifically for this caliber. Installation requires no gunsmithing, making it accessible for a wide range of users.
