The Daniel Defense DDM4 PDW Pistol (chambered in .300 AAC Blackout) is a compact, AR-style pistol built for close-quarters use & suppressed applications. It features a 7" cold hammer-forged, chrome-moly-vanadium S2W® barrel with 1:7 twist, threaded 5/8×24 TPI & a Daniel Defense Linear Compensator to direct muzzle blast forward. A 6" MFR XL M-LOK free-float handguard and ambidextrous GRIP-N-RIP charging handle enhance modularity & handling. The pistol-length gas system with a Maxim Defense CQB Pistol Brace & enhanced buffer system ensures reliable cycling with both subsonic & supersonic .300 BLK ammunition. At just 20.75" overall with the brace collapsed and weighing about 5.7 lb unloaded, the DDM4 PDW balances maneuverability with AR-style ergonomics. Built on mil-spec 7075-T6 aluminum upper & lower receivers, it includes a flared magazine well, M16-profile chrome-lined BCG, ambidextrous selector & oversized controls. It ships with a 30-round Magpul PMAG 300 BLK GEN M3 magazine and features Daniel Defense’s satisfaction guarantee.
