Why Choose the Maxim Defense PDX-SD Suppressed Pistol?
The PDX-SD is Maxim Defense’s flagship suppressed pistol platform, purpose-built around the 300 Blackout cartridge for optimal suppressed performance.

The inclusion of an ALG trigger provides a crisp, consistent pull, while the SCW Pistol System and SDX Two-Piece Handguard enhance ergonomics and accessory mounting options. The Urban Grey finish gives this pistol a modern, tactical appearance that stands out from traditional black firearms.
