The PDX-SD is the latest addition to Maxim’s SDX suppressor-tuned firearm lineup, engineered to dominate the short firearm market. They have designed a shorter, larger-diameter M-Kore equipped DSX suppressor specifically for the PDX, delivering an ultra-compact platform that shoots full-powered cartridges while remaining hearing safe. This PDX-specific suppressor features no barrel length restrictions, is built from military-grade materials, and is purposefully designed for each caliber. Integrated carbon cutters make cleaning easy, and the suppressor is fully user-serviceable, disassembling quickly with common tools. The PDX-SD enhances firearm reliability and service life by reducing gas blowback and minimizing cyclic rate increases, outperforming traditional suppressor designs.
