The MOD PX9 uses a dedicated 9mm Glock-magazine lower clearly marked MOD PX9, providing a purpose-built foundation for 9mm Luger. The magwell carries the PSA crest, and the selector is marked SAFE/FIRE. Ejection is to the right side.
Its slick-side upper omits both the forward assist and the ejection-port cover for a clean, streamlined profile. The bolt is marked G4-9, and the receivers are aluminum with a uniform matte black finish.
A 4-inch threaded barrel is paired with a cylindrical, forward-vented muzzle device. The free-float aluminum handguard integrates M-LOK slots and runs a continuous 1913 Picatinny top rail across the upper and handguard.
Stability and ergonomics come from the SB Tactical adjustable stabilizing brace in matte black and an A2-style pistol grip. The pistol operates via a semi-automatic, straight blowback system with a manual safety.
Manufacturer markings read Palmetto State Armory, West Columbia SC. The pistol is made in the United States and finished overall in matte black.
