The UDP-9 Pistol by Angstadt Arms stands as a testament to modern firearm engineering, offering the reliability and familiarity of the AR-15 platform in a compact 9mm configuration. Chambered for 9mm ammunition and accepting Glock magazines, this pistol ensures seamless operation with its last round bolt hold open feature, providing clear indication when it's time to reload.
Designed with efficiency in mind, the UDP-9 boasts a flared magwell that facilitates faster reloads under pressure. The integrated oversized trigger guard allows ease of use even with gloved hands. Both upper and lower receivers are crafted from robust 7075-T6 billet aluminum. Choose your aesthetic finish from matte black hard-coat anodized, Magpul Flat Dark Earth Cerakote, or Tactical Grey Cerakote.
This model features a sleek slick side upper receiver without forward assist or dust cover—an embodiment of streamlined functionality. A threaded bolt catch screw complements its precision assembly while accommodating standard AR-15 hammers through its specialized 9mm bolt assembly.
The heart of this firearm is its fire control group—a mil-spec AR-15/M4 setup compatible with most aftermarket PCC triggers for further customization potential. At just over six inches long, the chrome moly barrel comes equipped with an A2 style flash suppressor and is finished in black melonite for durability; it’s also threaded at 1/2x28 to accept suppressors if desired.
Ergonomics are enhanced by B5 Systems’ pistol grip alongside Angstadt Arms' own ultra-light M-LOK handguard spanning 5.5 inches—both contributing to an overall weight below five pounds across its compact length of merely twenty-two inches.
