Built on the P320’s modular architecture, this AXG Equinox uses a serialized stainless-steel FCU paired with SIG’s AXG metal grip module featuring an integral beavertail. The alloy frame provides the solid feel and balance many shooters prefer while retaining the P320’s flexibility.
The slide showcases the Equinox series two-tone aesthetic with black surfaces and brushed bright flats. It is marked EQUINOX and carries the SIG Custom Works crest. Forward and rear serrations aid manipulation, and the controls are finished in a bright/nickel-tone to complement the look.
The optics-cut slide comes fitted with a two-screw cover plate, and the pistol includes fixed sights: a front blade with a green dot and a fixed rear notch. A flat, skeletonized trigger provides a straight, consistent press.
Functional touches include a 3-slot Picatinny accessory rail on the dust cover, textured replaceable SIG SAUER grip panels, and a carry-length 3.9 inch barrel paired with a 17+1 capacity. Made in the USA, this Custom Works model is set up with three 17-round steel magazines.
