The X-Compact configuration balances concealability and performance. It uses a 3.6-inch barrel with a compact slide and the X-Series grip module to deliver a controllable, carry-friendly package in 9mm Luger with a standard 15+1 capacity.
The X-Series compact grip module features a fastback profile, extended beavertail, beveled magwell, and a deep undercut at the trigger guard. These details promote a consistent high grip and smooth reloads while maintaining a compact footprint.
The stainless-steel slide includes front and rear cocking serrations and is optics-ready with a removable rear sight plate and the factory cover plate installed. Fixed steel sights are equipped with a green-dot front blade and a square-notch rear on the removable plate for a clear, durable sight picture.
The striker-fired P320 system here incorporates a flat-faced trigger and a push-button magazine release. Its modular, serialized fire control unit allows configuration changes within the P320 family. An integral 1913-style accessory rail with four slots supports commonly used lights or accessories.
