The AXG Equinox Custom Works model combines an aluminum alloy grip module with a beavertail and flared magwell, giving this Carry-size P320 a solid, balanced feel. Nickel-plated controls and checkered grip panels complete the distinctive Equinox look.
The stainless steel slide wears Equinox polished flats and includes both front and rear serrations. It is optics-ready with the PRO footprint, compatible with Romeo1PRO and DeltaPoint Pro patterns, and ships with the cover plate installed.
A 3.9 in carbon steel barrel, striker-fired action, and a flat-faced, skeletonized trigger deliver a clean, consistent trigger press. Capacity is 17+1, and three steel 17-round magazines are included.
XRAY3 Day/Night sights provide a green ringed front dot and a square-notch rear for fast sight pictures in varied lighting. An M1913 accessory rail on the frame supports compatible lights or accessories.
Finished in a two-tone Equinox scheme over a black anodized aluminum frame, this SIG Custom Works limited release is made in the USA and configured in the Carry size for carry-friendly proportions.
