The pistol is made in the USA and carries distinctive Custom Works slide markings: left side "SIG SAUER P320" and right side "SIG" logo with "CUSTOM WORKS."
The factory 4.6 in barrel is marked "9mm x 19 1/2-28" and ships with a thread protector. Suppressor-height SIG X-RAY3 night sights include a high-visibility green front dot and a serrated rear notch for a clear sight picture.
The stainless steel slide wears a black Nitron finish and adds practical front and rear serrations. It is optics-ready with the cover plate installed, and this package includes a C&H optic plate. An MIL-STD-1913 (4-slot) accessory rail is integrated into the dustcover.
The FDE-anodized AXG alloy grip module provides a flared magwell, extended beavertail, replaceable grip panels and backstrap, and checkered panels. Controls include ambidextrous slide catch levers and a left-side magazine release. A flat-face, skeletonized trigger and striker-fired action complete the setup.
Capacity is 21+1 rounds, and this pistol includes three 21-round magazines. The slide features an optics cut with the cover plate installed from the factory, giving you flexibility to configure the pistol as needed.
