Sig Sauer P320 Compact/Carry 9mm Luger 3.9" Gold Barrel

The Sig Sauer P320 Compact/Carry 9mm Luger 3.9" Gold Barrel is a factory replacement barrel engineered for shooters who want to refresh their P320 Compact or Carry slide with a durable, corrosion-resistant upgrade. Built to Sig's exacting standards and finished in distinctive Titanium-Nitride gold coating, this barrel combines proven reliability with a striking appearance that sets your pistol apart on the range or in the field.

The Titanium-Nitride finish isn't just for show—it delivers tangible benefits where it counts. This PVD coating reduces friction and improves lubricity, which means smoother cycling, easier cleaning, and enhanced corrosion resistance compared to standard blued steel. If you carry or shoot your P320 regularly in varied conditions, that hard-anodized surface pays dividends in longevity and low-maintenance performance. The 3.9-inch barrel length is matched to the compact slide geometry, ensuring proper cycling and reliability with your existing P320 Compact or Carry frame and action.

Whether you're building a custom carry gun, refreshing a well-used duty weapon, or simply want a precision replacement barrel with aesthetic flair, this Sig factory part installs with confidence. It's held to the same tolerances and materials as the original—because your safety and function depend on it.
