SIG Sauer Inc. · Pistol · Limited Production · 2026
Also known as: P320-SXG Reserve, P320 SXG Reserve Comp, P320 Reserve
Overview
The SIG Sauer P320-SXG Reserve is a premium, all-steel evolution of the modular P320. It uses a stainless-steel frame and slide with a high-gloss polished DLC finish, an integrated expansion-chamber compensator to cut muzzle flip, a high-polish skeletonized flat-faced trigger, GridLOK polished grip panels and XRAY3 day/night sights on an optic-ready slide. Chambered in 9mm with 21-round magazines, it is positioned as SIG's luxury, flatter-shooting P320 flagship.

Notes
Described as a limited-run model available for roughly one year. The ~1310 g weight reflects all-steel construction and is the figure quoted with magazine. Width was not reliably published (a source value of 140 mm appears to duplicate the height figure) and is left null.
Background
SIG took the same modular fire-control unit that lets a P320 be reconfigured into dozens of forms and built its most extravagant version yet - a fully polished stainless 'SXG' with a built-in comp, aimed less at duty holsters than at the collector's safe.
