The PDX SD features an Arid Brown anodized aluminum upper and lower receiver with a full-length Picatinny rail for optics mounting, an M-Slot handguard for accessories, and a Maxim CQB brace in Arid Brown polymer. The 20+1 round capacity ensures you’re ready when it counts. The Arid Brown finish gives this pistol a distinctive, professional aesthetic that sets it apart on the range or in the field.
