Maxim Pdx Pstl 300blk 5.5" 20rd Blk

The Maxim PDX Pistol in 300 Blackout with 5.5-inch barrel and 20-round capacity represents a purpose-built platform engineered for close-quarters performance. Born from the SOCOM PDW solicitation, this subcompact firearm delivers exceptional power in an 18.75-inch overall length package, making it ideal for operators and shooters prioritizing compact handling without compromising on-target energy delivery.

Key specifications optimize this platform for modern tactical application. The direct impingement gas system provides reliable cycling across duty and training scenarios. The HATEBRAKE muzzle booster manages recoil signature while the ALG Combat Trigger delivers predictable break mechanics. The Maxim SCW PDW brace integrates a stable shooting platform within the compact form factor. At 8.56 pounds loaded with the 20-round magazine, the PDX balances ergonomics and controllability. The 300 Blackout cartridge—subsonic-capable and rifle-powered—maintains energy at distance while excelling in high-pressure tactical environments where penetration and barrier performance matter.

This platform serves law enforcement, military, and civilian operators who operate in environments demanding compact firepower. The PDX excels in vehicle operations, room entries, and scenarios where traditional rifle length compromises mobility. Shooters transitioning from AR-15 platforms find familiar controls and ergonomics. The 300 Blackout chambering appeals to those leveraging suppressor-ready subsonic loads or seeking rifle-caliber terminal performance in a PDW-class system.

The PDX fills a specialized role within the modern rifle ecosystem—larger than a pistol-caliber carbine but substantially more compact than full-length rifles. The 5.5-inch barrel in 300 Blackout preserves velocity while the short overall length delivers the maneuverability advantage operators demand in CQB-heavy missions.
