Sig Sauer P320 Subcompact/XCompact 9mm Luger 3.6" Gold Barrel

The Sig Sauer P320 Subcompact/XCompact 9mm Luger 3.6" Gold Barrel is a factory replacement barrel built for shooters who want to maintain or restore their P320 platform. Whether you're replacing a worn barrel, swapping finishes, or building a custom configuration, this Sig OEM barrel delivers the precision and reliability you expect from the P320 ecosystem. The gold titanium nitride coating isn't just for looks—it offers enhanced durability and corrosion resistance compared to standard steel, making it a practical upgrade for duty, competition, or serious carry use.

This barrel is engineered to fit both the P320 Subcompact and P320 XCompact frames, giving you flexibility in how you configure your pistol. The 3.6" length strikes a balance between maneuverability in a compact package and enough sight radius for accurate shooting. Since it's a genuine Sig part, you're getting the same tolerances and materials Sig uses in factory builds—there's no guessing about fit or function.

If you run a P320 as an EDC, home defense, or range gun and you're thinking about a barrel swap—whether for maintenance, customization, or as a spare—this is the straightforward choice. Drop-in installation means you don't need a gunsmith or special tools to get back in the fight.
