Angstadt Arms UDP-9 9mm Pistol 15+1 6" Threaded Barrel M-LOK

The Angstadt Arms UDP-9 delivers precision-engineered performance in a compact 9mm platform designed for versatility and reliability. This pistol combines proven engineering with modern manufacturing techniques to create a firearm that excels in multiple applications.

What Makes This Different

The UDP-9 features a 6-inch melonite-treated barrel that provides superior corrosion resistance and extended service life compared to standard nitride finishes. The free-floating M-LOK handguard system eliminates barrel contact for improved accuracy potential, while the threaded muzzle accepts standard 1/2x28 accessories. The aluminum Picatinny rail receiver with black Cerakote finish offers enhanced durability over polymer alternatives.

Key Features

• 6-inch melonite-treated threaded barrel (1/2x28 TPI) for suppressor compatibility
• 5.50-inch free-floating M-LOK handguard with multiple attachment points
• Black Cerakote aluminum Picatinny rail receiver for optics mounting
• 15+1 capacity with standard Glock-pattern magazine compatibility
• B5 Systems grip with ergonomic texturing for secure handling
• Direct blowback operating system for simplified maintenance
• MIL-STD 1913 top rail for optics and accessories

The UDP-9's direct blowback action cycles reliably with a wide range of 9mm ammunition weights, from 115-grain target loads to 147-grain subsonic rounds. The platform performs consistently in competitive shooting environments and tactical applications. The melonite barrel treatment maintains accuracy through extended firing schedules while resisting fouling buildup.
