The AXG (Alloy XSeries Grip) module gives this P320 a metal frame for added heft, textured G-10 grip panels, and an extended beavertail that balances recoil control with carry comfort.
Custom Works applies the Equinox treatment by polishing the stainless slide flats and pairing them with a black Nitron finish everywhere else, creating a crisp two-tone profile that is unique among P320 variants and previously reserved for classic SIG hammer-fired pistols.
The slide is cut for SIG-pattern micro red-dot optics and retains XRAY3 day/night sights, providing out-of-the-box low-light capability and easy co-witnessing. Forward and rear cocking serrations aid manipulation.
A flat-face, skeletonized trigger delivers a consistent striker-fired pull, while nickel-finished controls and a removable magwell accent the premium build. All components are built in the USA, and the pistol retains full P320 modularity for future caliber or size conversions.
