Sig Sauer P365 9mm Luger 3.10" Replacement Barrel - Gold Titanium Nitride - LCI

The Sig Sauer P365 replacement barrel is a factory-original 9mm Luger barrel engineered to drop into the P365, P365X, and P365-XMacro pistol platforms. Machined from steel and finished in a striking Gold Titanium Nitride (TiN) coating, this 3.10" barrel is built to the same dimensions as the factory-original and is fully compatible with both SAS ported and non-ported P365 slides.

The barrel integrates a Loaded Chamber Indicator (LCI) that provides both tactile and visible confirmation of a chambered cartridge, a safety feature designed into the P365 series for confident handling. The Gold Titanium Nitride finish delivers a bright, eye-catching accent while adding surface hardness and corrosion resistance to the steel substrate, helping the barrel hold up to regular range use and the rigors of everyday concealed carry.

Designed and tested by Sig Sauer for the P365 family of micro-compact pistols, this replacement barrel is intended for shooters who want a factory-spec spare or who want to swap the look of their P365-series carry gun. No sights are included on the barrel itself, as the P365 platform uses slide-mounted sighting. Whether you are replacing a worn factory barrel or simply adding a colored accent to your carry setup, this Sig Sauer P365 Gold TiN barrel delivers direct-from-the-manufacturer fit and function.
