CMMG Banshee MK4 9mm 5" Pistol - Midnight Bronze Finish

The CMMG Banshee MK4 9mm pistol delivers compact firepower with precision engineering in a 5-inch barrel configuration. This pistol-caliber carbine platform bridges the gap between rifle accuracy and pistol maneuverability. The Midnight Bronze Cerakote finish provides superior corrosion resistance while maintaining a professional appearance.

What Makes This Different

The Banshee MK4 utilizes CMMG's proven radial delayed blowback operating system, eliminating the need for a buffer tube while reducing felt recoil compared to straight blowback designs. This system allows for a more compact overall length without sacrificing reliability. The platform accepts standard Glock magazines, providing widespread compatibility and cost-effective ammunition feeding.

Key Features

• Radial delayed blowback system reduces recoil and eliminates buffer tube requirement
• 5-inch barrel with 1:10 twist rate optimized for 9mm projectiles
• Midnight Bronze Cerakote finish rated for 2,400+ hours salt spray resistance
• M-LOK compatible handguard with integrated Picatinny rail sections
• Accepts standard Glock 17/19 magazines for widespread compatibility
• Ambidextrous safety selector and magazine release controls
• SB Tactical pistol brace compatible (where legally permitted)

The compact 5-inch barrel configuration makes this platform suitable for close-quarters applications while maintaining sufficient velocity for personal defense ammunition. The radial delayed blowback system cycles reliably with both subsonic and standard pressure 9mm loads. Law enforcement agencies have adopted similar CMMG platforms for vehicle-based operations where space constraints limit traditional rifle deployment.
