Description

The CMMG Banshee Mk17S 9mm 8" AR Pistol is a modern semi-automatic pistol purpose-built for shooters who demand AR-platform ergonomics in a compact, maneuverable package. Designed for tactical applications, home defense, and training, this platform bridges the gap between traditional pistols and short-barreled rifles by leveraging modular AR architecture while remaining classified as a pistol. The 8-inch barrel and 21+1 round capacity provide legitimate stopping capability and round count for dynamic scenarios where every round counts.

Built on the proven AR-15 platform, the Banshee Mk17S uses standard AR controls and ergonomics, meaning shooters familiar with modern rifles transition seamlessly—safety levers, charging handles, and trigger geometry are immediately intuitive to trained users. The 8-inch barrel optimizes velocity and terminal performance from 9mm ammunition while keeping overall length compact for indoor engagement and vehicle use. CMMG's Banshee platform is known for reliability and durability, with components engineered to AR-15 tolerances; the generous 21-round magazine capacity combined with quick magazine changes makes this pistol practical for sustained engagement and follow-up shots without reloading delays.

Law enforcement trainers and defensive shooters benefit most from the Banshee Mk17S because it eliminates the learning curve of traditional pistol platforms while delivering higher round capacity and faster target reacquisition through AR ergonomics. Home defenders and tactical trainees appreciate the modularity—barrel, bolt carrier groups, and furniture are AR-standard and widely available, allowing customization and parts compatibility across the ecosystem. At 9.5 pounds, it balances maneuverability with controllability; the compact 13.5-inch length makes it suitable for close-quarters work and confined spaces where longer rifles prove unwieldy. This platform is street-proven and trusted by professionals who require reliability without compromise.
