Wilson Combat-Customized Sig Sauer P320 X-Compact 9mm with TiN Barrel & Optic-Ready Slide
This modular P320 X-Compact pairs Sig Sauer’s proven striker-fired fire control unit with Wilson Combat’s performance-driven upgrades. A TiN-coated gold barrel, flat skeletonized trigger, and weight-balanced WC grip module elevate handling and aesthetics, while the ported, optic-cut slide keeps the 17-round pistol ready for red-dot use. Built in the USA and tuned for carry-size control with full-size capacity, this is a turnkey package for shooters who want factory reliability and custom features in one.

The modular, serialized fire control unit (FCU3490XX) is TiN coated for both wear resistance and its distinctive gold finish, and it drops into a Wilson Combat X-Compact grip module that adds tungsten weight rods and an integral flared magwell for faster, more controlled reloads.
A TiN-coated 3.6-inch stainless barrel and matching flat-faced trigger provide a crisp break and striking visual contrast against the black Nitron/DLC slide. The slide itself is ported with lightening windows, front and rear serrations, and a direct-mount optic cut capped by a C&H cover plate.
Ambidextrous slide-stop levers and a reversible, bronze-anodized, textured magazine release offer left- and right-hand accessibility. A 3-slot MIL-STD-1913 rail at the dust cover supports lights or lasers without additional adapters.
Green fiber-optic front and serrated rear sights give a bright, glare-free sight picture out of the box, and the optic cut accepts popular MRDS footprints when it’s time to run a red dot. Despite its compact slide and barrel, the included 17-round magazines deliver full-size capacity.
