The full-size P320 configuration pairs a 4.7 in carbon steel barrel with a Black Nitron-finished slide that has front and rear cocking serrations for confident manipulation. The striker-fired action and curved trigger provide a consistent trigger press. The polymer grip module houses a stainless steel receiver for strength and longevity.
At the core is Sig Sauer's modular, serialized stainless steel fire control unit, allowing grip and slide swaps within the P320 family. Takedown is tool-free and does not require pulling the trigger, supporting safe and straightforward maintenance.
The slide is not optic cut and wears steel 3-dot contrast sights: a dovetailed white-dot front post and a dovetailed square-notch rear. A full-length M1913/Picatinny accessory rail on the dustcover supports light or laser attachment as needed.
Chambered in 9mm Luger with a 17+1 capacity, this model (MFG Part Number 320F-9-B) includes two 17-round magazines. The frame is marked EXETER, NH, and the factory case label indicates 28-DEC-2016, highlighting a documented configuration and date of packaging.
