Maxim Defense Pdx Pstl 5.56 5.5" 20-Round Pistol

The Maxim Defense PDX Pistol 5.56 5.5" with 20-round magazine capacity is a purpose-built pistol designed for operators who demand compact 5.56 NATO firepower in a highly maneuverable platform. This tactical rifle-caliber pistol bridges the gap between traditional handguns and short-barreled rifles, delivering intermediate rifle power in a footprint suitable for vehicle operations, close-quarters engagement, and specialized tactical applications. Built by Maxim Defense Industries—a manufacturer with deep roots in military and law enforcement innovation—the PDX Pistol serves agencies and end-users requiring precision 5.56 performance without a tax-stamped short-barreled rifle classification.

The 5.5-inch barrel delivers optimized velocity and terminal ballistics for 5.56 NATO ammunition while maintaining a compact overall length of 12 inches, critical for confined spaces and rapid target transitions. The pistol's design leverages proven Maxim Defense engineering, including controlled recoil management and reliable feeding via a 20-round magazine—the standard capacity for sustained combat effectiveness. At 8.69 pounds, the weapon maintains a balanced platform that reduces operator fatigue during extended operations while preserving the structural integrity necessary for reliable cycling and consistent accuracy downrange. The configuration supports mission-critical modularity, allowing integration with modern optics, lights, and accessories through standardized Picatinny rail systems.

Tactical operators, specialized law enforcement units, and private security professionals benefit most from the PDX Pistol's rapid deployment capability and penetration characteristics superior to traditional 9mm platforms. The firearm excels in vehicle-mounted operations, room-clearing scenarios, and environments where barrel length restrictions prevent short-barreled rifle use. Users must verify local and federal firearms regulations regarding pistol classification and any applicable registration requirements before purchase. Proper training and ammunition selection—standard 5.56 NATO or .223 Remington—ensure optimal function and safety. This is a firearm requiring FFL transfer and background check for legal acquisition.
