Maxim Defense PDX (300 Blackout) Pistol

Born from the SOCOM PDW solicitation and voted BEST OF SHOT 2019 by RECOIL Magazine, the Maxim Defense PDX™ delivers uncompromising performance in a subcompact 5.56 NATO, 7.62×39, or .300 BLK platform. Engineered for Tier 1 close-quarters applications, the PDX™ measures just 18.75″ in overall length, making it the ultimate PDW for confined, urban, or vehicle-based operations.

At the heart of the PDX™ is our patented SCW™ system—a 4″ stock system with an integrated bolt carrier group and interchangeable buffer weights, giving you enhanced recoil control, faster follow-ups, and improved reliability across calibers. Out front, the PDX™ comes standard with the Maxim HATEBRAKE™ muzzle booster, installed under the handguard to reduce recoil, decrease flash signature, and redirect blast forward—ideal for use in close-quarters or suppressed environments.

Looking to run suppressed? Specifically engineered for barrel lengths as low as  5.5″, our DSX Suppressors are the perfect companions for the PDX™. Its direct thread, HUB-compatible, or BUB-compatible Quick Detach options and high-flow design reduce backpressure while maintaining accuracy, making it an ideal choice for short-barrel suppressed platforms like the PDX™.

Additional enhancements include a rigid upper receiver with HK-height rail, a fully ambidextrous control setup, and a 2 MOA-accurate barrel for precision at short to mid-range. Built from military-grade materials and tested in demanding conditions, the PDX™ is ready for duty right out of the box.
