Maxim Defense Sps Pdx 300blk 5.5" 20-Round Pistol

The Maxim Defense SPS PDX 300blk 5.5" 20-Round Pistol is a purpose-built platform designed for operators who require compact, magazine-fed rifle performance in a pistol form factor. It is ideal for tactical professionals, law enforcement breaching teams, and precision rifle enthusiasts. This 300 Blackout pistol offers the versatility of subsonic and supersonic ballistic performance, making it a preferred choice for both suppressed and unsuppressed applications.

Weighing 7.94 lbs and featuring a 5.5-inch barrel, the Maxim Defense SPS PDX strikes a balance between firepower and maneuverability, which is critical for vehicle operations and close-quarters battle scenarios. The SPS (Short Pistol System) utilizes a short-stroke gas piston operating system, designed to cycle reliably with both subsonic and supersonic 300 Blackout loads, a feat that blowback and direct-impingement designs often struggle to achieve. The 5.5-inch barrel is engineered to provide sufficient dwell time for complete powder burn, optimizing velocity and terminal performance.

With a 20-round magazine capacity, the SPS PDX ensures adequate firepower for tactical engagements without excessive bulk. The PDX designation reflects Maxim's commitment to modern ergonomic controls, making it compatible with standard tactical platforms and accessories. Precision machining and controlled tolerances guarantee repeatable accuracy and durability under sustained use.
