The modular P320 architecture with a serialized, removable FCU offers flexibility in grip modules and configurations while maintaining the same core fire control unit. This example is the Full-Size 9mm variant with a 17+1 capacity and a striker-fired, curved trigger.
The pistol has a factory 4.7 in threaded barrel, and it has a threaded barrel with a common 1/2x28 pattern. The slide is optics-ready with the rear-sight cover plate installed, finished in black Nitron, and cut with forward and rear serrations for confident manipulation.
Suppressor-height iron sights pair a tall front post with a tall square-notch rear for a clear sight picture, including when used with a mounted optic. The full-size polymer grip module provides a stable hold, and the 4-slot Picatinny/1913 accessory rail supports compatible lights or accessories.
The pistol is assembled/marked NEWINGTON, NH, USA. The packaging label is present but mismatched to this pistol. Two 17-round steel magazines marked 'MADE IN USA' are included.
