Maxim Defense PDX SD 300 Blackout Pistol with Integrated Suppressor – MXM47847

The Maxim Defense PDX SD in 300 Blackout is one of the most advanced and compact personal defense pistols on the market, engineered for operators and serious enthusiasts who demand suppressed performance without the bulk of a traditional suppressor setup. Built around Maxim Defense’s proprietary integrated suppressor barrel technology, this 5.50″ barrel delivers hearing-safe capability in an ultra-compact, mission-ready package.

Chambered in 300 Blackout, the PDX SD is purpose-built to maximize the performance of both supersonic and subsonic ammunition, making it an exceptional choice for home defense, range use, and tactical applications. The black DLC-coated aluminum receiver features a full-length Picatinny rail for mounting optics, lights, or accessories, while the M-Slot handguard provides additional attachment points for mission-specific configurations.

The PDX SD ships with a 20+1 round capacity and is fitted with Maxim Defense’s signature CQB pistol brace, offering a stable, ergonomic shooting platform in an extremely short overall footprint. The polymer grip and pistol brace combination keep the platform lightweight and maneuverable without sacrificing control or accuracy.

Whether you’re a competitive shooter, home defender, or a collector of premium-grade firearms, the Maxim Defense PDX SD represents the pinnacle of compact suppressed pistol engineering.
