The Compact PRO variant pairs a striker-fired system with a flat-faced trigger and a reversible magazine release, giving this model the control layout many shooters prefer. The serialized, removable fire control unit (FCU) makes the P320 platform modular while maintaining the legal receiver component within the FCU.
The slide features front and rear cocking serrations and is factory optics-ready using the R2/Pro footprint, compatible with SIG ROMEO1PRO and Leupold DeltaPoint Pro. SIG X-RAY3 tritium 3-dot night sights are installed, with a high-visibility green-ring tritium front sight marked "TG-H3" and a dovetailed tritium rear.
The compact 3.9" barrel and 15+1 capacity strike a practical balance for carry and range use. An integral Picatinny accessory rail on the grip module supports common weapon lights and accessories without additional adapters.
This pistol is finished in black with a durable slide and a polymer grip module that has aggressive molded grip panels for purchase. The factory case label is dated April 1, 2020, and the included magazines are marked from both U.S. and Italian production.
