The Maxim Defense PDX Pistol in .300 Blackout with 5.5" barrel and FDE finish represents a purpose-built platform for suppressed fire and compact carbine applications. Designed for operators who require subsonic performance without sacrificing accuracy or ergonomics, this .300 Blackout pistol bridges the gap between handgun portability and intermediate rifle power. Built by Maxim Defense Industries—recognized for their engineering in short-barrel and integrally suppressed systems—the PDX pistol serves law enforcement tactical teams, military operators, and civilian shooters prioritizing stealth and terminal effectiveness in confined spaces.

The 5.5" barrel optimizes velocity for .300 Blackout subsonic and supersonic ammunition while maintaining a compact footprint ideal for vehicle ops, close-quarters battle, and breaching scenarios. The PDX platform incorporates Maxim Defense's gas-piston operating system, delivering reliable cycling with suppressors installed and consistent lockup across varying ammunition types. The Flat Dark Earth (FDE) finish provides non-reflective surface treatment suited to tactical environments, and the 20-round capacity delivers substantial firepower for duty or defensive applications. At 8.63 lbs unloaded, the pistol maintains manageable weight for prolonged operations without compromising structural rigidity or control during rapid fire sequences.

This .300 Blackout pistol benefits operators transitioning from AR platforms seeking consistent ergonomics and ammunition compatibility with existing inventories. The PDX's modular design supports aftermarket rail systems, optic mounts, and suppressor attachment—critical for mission-specific configuration in tactical loadouts. Shooters will appreciate suppressor-ready design and reliable function with both supersonic and subsonic loads, making the Maxim Defense PDX Pistol a versatile choice for defense, training, and professional applications requiring precision and discretion.
