SIG Sauer P320 AXG Custom Works Compact 9mm Pistol – Optic-Ready, Custom Lightened Slide, FDE Alloy Frame
The P320 AXG Custom Works pairs SIG Sauer’s proven striker-fired fire-control unit with a factory-built alloy XSeries Grip (AXG) module, delivering a modular 9mm that feels solid in the hand while remaining compact and light for carry. This build adds a black Nitron slide featuring three lightening windows and a direct-mount RMR-pattern optic cut, giving shooters a balanced mix of reduced reciprocating mass, faster sight tracking, and immediate red-dot compatibility.

What’s Included
- SIG Sauer P320 AXG Custom Works 9mm pistol
- One 17-round factory SIG Sauer P320 steel magazine
The heart of this pistol is SIG’s modular, serialized fire-control unit, letting owners swap calibers and grip modules without another FFL transfer—ideal for tailoring the gun to multiple roles.
The AXG grip frame is precision-machined from aluminum alloy and finished in Cerakote Flat Dark Earth. Added weight over a polymer module tames recoil, while undercut trigger guard texturing and black grip panels provide a secure purchase.
A black Nitron slide is factory-milled for RMR, Romeo1Pro, and Leupold DPP-pattern optics. Three window cuts on top reduce slide mass for flatter cycling and showcase the 3.9 in barrel. Forward and rear serrations make manipulations solid in any condition.
The flat-faced, skeletonized X-Series trigger breaks at 90° for a clean, repeatable pull. Paired with a green fiber-optic front sight, square-notch rear sight on the optics plate, and a 5.8 in sight radius, the pistol offers fast sight acquisition whether running irons or a dot.
An integral M1913 accessory rail supports lights or lasers, and the compact profile conceals easily while still housing a full-capacity 17-round magazine.
