Angstadt Arms UDP-9 9mm 16" 16-Round Threaded Barrel Carbine

The Angstadt Arms UDP-9 9mm 16" 16-Round Threaded Barrel Carbine represents a purpose-built platform designed for shooters who demand reliability, modularity, and precision in a compact 9mm carbine. Built on the proven UDP (Unified Defensive Platform) design, this carbine bridges the gap between pistol-caliber versatility and rifle-class ergonomics, making it ideal for defensive applications, tactical training, and civilian sport shooting. The 16-inch barrel length delivers optimal velocity and accuracy in 9mm while maintaining overall portability for vehicle storage and close-quarters operations.

At 8.2 pounds, the UDP-9 strikes an efficient weight-to-performance balance, reducing shooter fatigue during extended training or duty cycles. The threaded barrel accommodates suppressors, compensators, or flash hiders, giving operators complete control over muzzle devices to suit their specific mission profile. The 16-round magazine capacity and reliable direct-impingment action ensure consistent feeding and function across diverse ammunition types, critical for duty-grade performance. The carbine's modular design allows for AR-pattern accessory integration, enabling users to customize furniture, grips, optic mounts, and rail systems to their exact specifications without gunsmithing.

Law enforcement, military personnel, and serious civilian shooters benefit most from the UDP-9's balance of compact form factor and full-size carbine capability. The 16-inch configuration is optimized for indoor facility transitions and vehicle deployment while delivering superior velocity compared to pistol-length alternatives. This carbine pairs seamlessly with common AR-pattern optics, sighting systems, and accessory rails, making integration into existing equipment ecosystems straightforward. The threaded barrel and modular design make the Angstadt Arms UDP-9 an excellent platform for shooters who value precision, reliability, and adaptability.
