The SIG SAUER P320 AXG Equinox is a premium, optics-ready pistol built for the shooter who demands both performance and presentation. It features SIG’s proven modular FCU housed in a custom aluminum alloy grip module with aggressive G10 grips. This model has been a consistent seller since we added it to our inventory in spring 2025, proving its popularity with our customers who appreciate a duty-ready pistol with refined aesthetics.
Why This One?
- AXG Aluminum Grip Module: Provides a solid, all-metal foundation with excellent weight distribution and a superior feel compared to polymer frames.
- Optics-Ready System: The slide is cut from the factory to accept SIG’s ROMEO1PRO and other popular micro red dots without the need for an adapter plate.
- Enhanced Controls & Sights: Features an extended slide catch lever, flat skeletonized trigger, and high-visibility X-RAY3 Day/Night sights for a fast, positive sight picture.
- Refined Fit & Finish: Our staff has noted that the machining and assembly on this current production run exhibit noticeably tighter tolerances than previous versions we’ve handled.
- Balanced Performance: The combination of the aluminum frame and slide serrations offers exceptional control for rapid follow-up shots and confident handling.

Q & A
Is the slide cut compatible with Holosun optics?
Yes. The slide uses SIG’s proprietary ROMEO1PRO footprint, which is also compatible with the Holosun 507C, 508T, and 509T models using the appropriate mounting plate from Holosun or a third-party manufacturer.
Does the aluminum frame make a significant difference?
Absolutely. The AXG module provides a more rigid platform that reduces flex and improves the overall balance of the pistol. The added weight, minimal as it is, also helps mitigate muzzle rise for faster recovery between shots.
What holsters fit the AXG Equinox?
It will fit most holsters designed for the standard P320 Carry or Full-Size models, provided the holster accommodates the slightly wider profile of the thumb safety and the unique contour of the AXG grip module. We recommend checking with the holster manufacturer for specific AXG compatibility.
