ZEV P320 XCompact Octane 9mm – Custom RMR-Ready GunMod with Match Barrel & 21-Round Capacity
This ZEV-built SIG Sauer P320 XCompact Octane delivers a factory-custom blend of performance parts and modern features in a modular, carry-size package. A dimple-fluted, DLC-finished match barrel, window-ported Octane slide, and flat red trigger give it true upgrade appeal, while the Wilson Combat starburst grip module and RMR-footprint optic cut make it ready for tailored ergonomics and fast sight acquisition right out of the box.

- SIG Sauer hard plastic pistol case

The Octane slide wears an eye-catching gray/black two-tone finish, aggressive front and rear serrations, and twin window ports that showcase the match-grade barrel while aiding cooling and reducing reciprocating mass.
Inside, the 3.6 inch stainless-steel barrel features precision dimple fluting and a durable DLC coating for reduced friction and long service life. The modular, serialized P320 fire-control unit (FCU) lets you swap frames, slides, or calibers with genuine SIG or aftermarket components.
Controls are optimized for speed: a flat-faced, skeletonized red aluminum trigger breaks cleanly, and the compact Wilson Combat starburst grip module adds texture and an undercut trigger guard for a higher, more secure hold.
Fiber-optic irons include a bright green ZEV front post and a serrated rear notch, and the slide’s RMR-pattern optic cut accepts popular red-dot sights without additional milling; mounting hardware is included.
