As part of the Custom Works Reserve Collection, the P320-SXG Reserve is a small-batch, limited-edition release with collector appeal. Its high-polish DLC finish is applied to the slide and steel frame for a uniform, presentation-grade look that also delivers surface hardness and sheen.
The SXG all-steel grip module features replaceable GridLOK-pattern grip panels, a checkered frontstrap and backstrap, and a flared magwell to speed reloads. A 3-slot Picatinny accessory rail is integrated into the dustcover for mounting approved lights or accessories.
The slide is cut for optics and includes front and rear serrations for easy manipulation. An integrated two-port compensator is built into the slide assembly to help manage muzzle rise while keeping the overall length compact with a 3.9 inch barrel.
Sight alignment is straightforward with three-dot iron sights, combining a green-dot front sight marked "TG-H3" and a two-dot rear night sight. Capacity is 21+1 in 9×19 with the included factory steel magazines.
Built on the modular P320 FCU architecture and striker-fired action, this United States–made model blends the adaptability of the P320 system with premium materials and finishing tailored for the Reserve Collection.
