The P320’s modular design centers on its serialized fire control unit.

The grip module’s interior is marked "NEWINGTON, NH, USA."
The Compact configuration features a 3.9-inch barrel and a stainless, matte light gray slide with front and rear cocking serrations. The slide is not optics cut. Operation is striker-fired with a short-recoil, semi-automatic action and no external manual safety.
