The P365X configuration features a stainless steel slide with a Nitron black finish, front and rear cocking serrations, and an external extractor. The slide is optic-ready with a Compact (Shield RMSc) footprint, and the dovetailed square-notch rear sight sits on the sight plate. XRAY3 Day/Night sights include a bright green front dot for fast sight acquisition in varied lighting.
Its 3.1 in carbon steel barrel works with a striker-fired, locked-breech short-recoil action. The flat-faced trigger and push-button magazine release support a consistent, modern control layout. Capacity is 12+1 with the included flush 12-round magazines.
The polymer XSeries P365 grip module adds enhanced texturing and a subtle magwell flare to streamline reloads while maintaining a compact profile. A SIG proprietary accessory rail provides mounting for compatible lights or accessories. This non-MS variant omits a manual safety lever for a streamlined setup.
Factory details include the NEWINGTON, NH USA slide/frame marking and the SKU/mfg part number 365X-9-BXR3 as confirmed on the case label. The pistol is made in the USA and is the micro size within SIG's XSeries lineup.
