This Professional-series P320 was produced for police and government contracts and only reached the commercial market as an Agency Vault overrun, giving it provenance that sets it apart from standard production guns.
The full-size X-Series grip module features an extended beavertail, deep trigger-guard undercut, and an integral four-slot M1913 rail for lights or lasers, providing solid control and accessory flexibility.
A carbon-steel slide wears a black Nitron finish and sports both front and rear cocking serrations plus a factory optic cut compatible with SIG Romeo2, Romeo1PRO, and Leupold DeltaPoint Pro footprints, allowing direct mounting without adapter plates.
The flat-faced X-Series trigger shortens reach and offers a crisp break, while the modular fire-control unit (the serialized component) lets owners change frames, slides, and calibers within the P320 ecosystem.
XRAY3 tritium day/night sights combine a high-visibility green dot front with a serrated rear, giving clear sight pictures in all lighting conditions straight out of the box.
