What’s Included
- SIG SAUER factory hard case
- SIG SAUER owner's manual
- Flared magazine-well funnel (installed)

The X-Series slide incorporates front and rear serrations, an external extractor, and an integral two-port compensator that vents through the slide (the barrel itself is not ported). The slide is finished in Nitron and includes an optics-ready cut with cover plate and an RMSc-pattern footprint for straightforward micro-dot mounting when desired.
The Macro-Compact polymer grip module provides an aggressive molded texture and a three-slot 1913 accessory rail. A flared magwell funnel is installed on this example, aligning with the extended 21-round steel magazines included with this listing.
SIG's XRAY3 day/night sight set pairs a front sight with a bright green ring/dot and a dovetailed rear notch for a clear, consistent sight picture. The flat-faced trigger and left-side magazine release support a clean trigger press and intuitive control layout.
This pistol uses the modular P365 fire-control unit, allowing compatibility with other P365 grip modules. The model code 365XCA-9-COMP is confirmed by the case label, and the firearm is made in the United States.
