Maxim Defense PDX:SD

Maxim Defense Industries · Personal Defense Weapon · In Production · 2022

Overview

The Maxim Defense PDX:SD is the integrally suppressed evolution of the PDX, mating the ultra-compact SCW-braced platform with a permanently integrated DSX suppressor built on Maxim's M-Kore technology. The user-serviceable suppressor incorporates carbon cutters and is tuned per caliber to keep the package hearing-safe even with full-power cartridges, while only adding roughly five inches of overall length over the standard PDX. Chambered in .300 BLK, 5.56 NATO or 7.62x39, it is built from military-grade titanium, stainless and aluminum.
