The Sig Sauer P320 Subcompact 3.6" barrel is a factory replacement part engineered for P320 Subcompact and XCOMPACT pistols. If you're running a modular P320 build or need to refresh the barrel on your carry gun, this Gold Titanium-Nitride finished barrel delivers both aesthetic appeal and practical performance. The Gold finish isn't just for looks—the titanium-nitride coating boosts lubricity, which means smoother operation and easier cleaning over the life of the barrel. This is genuine Sig hardware, held to the same rigorous testing standards as factory originals.
One critical compatibility note: this barrel works only with non-loaded chamber indicator (LCI) slides and frame sets. If your P320 Subcompact or XCOMPACT has an LCI—that small loaded chamber pop-up safety indicator on the slide—this barrel will not function correctly with your gun. Double-check your slide before ordering. The 3.6-inch length is fixed (not threaded), so you won't be running suppressors or flash hiders with this setup, but that keeps things simple for a reliable carry or duty configuration.
Whether you're dealing with wear on your current barrel, building a second upper, or just want to swap finishes for a fresh look, a factory barrel swap is one of the easiest P320 maintenance tasks. Drop it in, and you're back in business with no guesswork on fit or reliability.
| Model | Sig Sauer P320 Subcompact / XCOMPACT |
| Barrel Length | 3.6 inches |
| Caliber | 9mm Luger |
| Barrel Finish | Gold Titanium-Nitride |
| Threaded | No |
| Loaded Chamber Indicator | Not compatible with LCI slides |
No. This barrel is compatible only with non-LCI slides. If your P320 Subcompact or XCOMPACT has a loaded chamber indicator (a small pop-up indicator on the slide), this barrel will not work with your gun. Verify your slide before purchasing.
No. This barrel is non-threaded, so it cannot accommodate a suppressor or muzzle device that requires threading. The fixed barrel design keeps the setup simple and reliable for standard carry or duty use.
The titanium-nitride coating provides increased lubricity, which improves the smoothness of operation and makes the barrel easier to clean and maintain over time. It's also a durable, attractive finish.
Yes. This is a factory replacement barrel designed and tested by Sig Sauer to the same specifications and quality standards as original equipment.
