Maxim Defense PDX:SD .300 BLK Pistol with Maxim DSX Suppressor - Arid FDE

Maxim Defense PDX:SD .300 BLK Pistol with Maxim DSX Suppressor - Arid FDE

Re-engineering the boundaries of ultra-compact personal defense weapon (PDW) performance, the Maxim Defense PDX:SD .300 BLK Pistol with Maxim DSX Suppressor delivers whisper-quiet, hearing-safe firepower in an agile pistol configuration. Purpose-built from the ground up as a suppressor-tuned system within Maxim’s SDX lineup, the PDX:SD pair an ultra-short 5.5-inch barrel with a custom-engineered DSX suppressor utilizing M-Kore™ technology. Finished in an attractive Arid (Flat Dark Earth) Type III hard coat anodizing, this 300 Blackout pistol generates full-velocity energy while drastically reducing gas blowback, heat buildup, and cyclic wear on internal components.

At the center of its silent lethality, the platform-specific DSX suppressor is constructed from military-grade titanium (6Al-4V), 17-4 stainless steel, and 7075/6061 billet aluminum, carrying no barrel length restrictions under hard firing schedules. Integrated carbon cutters make field maintenance effortless, allowing the suppressor to be fully serviced with common tools. Outfitted with a fast-stabilizing 1:5" twist barrel, a compact Maxim GEN:6 CQB Pistol Brace for maximum stability in a minimal footprint, and a durable DLC/anodized coating, the PDX:SD Pistol collapses down to just 23.75 inches for seamless vehicle transport and close-quarters maneuverability.
