The heart of this P320 Compact is its modular design with a removable, serialized stainless-steel FCU. The FCU is visible through the frame window and allows grip module swaps while maintaining the serialized core, a hallmark of the P320 system.
Its compact 3.9 inch steel barrel pairs with a matte black slide that includes front and rear serrations and a beveled nose for easy manipulation and holstering. The slide is non-optics-cut. The barrel hood is marked "9mm x 19."
Sight alignment is fast and familiar thanks to dovetailed white 3-dot sights. An integral 1913-style accessory rail provides mounting space for compatible lights or accessories.
The polymer grip module has molded texturing and a textured left-side magazine release. This striker-fired, semi-automatic pistol is chambered in 9mm Luger with a 15+1 capacity and ships with three magazines featuring witness holes to 15. The frame is marked "NEWINGTON, NH, USA," reflecting its USA manufacture. This model has no external manual safety.
