True Precision TPP365FBXG Sig P365 Fuse 9mm Luger 4.30" Gold TiN 416R Stainless Threaded Drop-In Barrel

The True Precision TPP365FBXG is a drop-in replacement barrel built specifically for the Sig Sauer P365-FUSE pistol. Chambered in 9mm Luger, it is machined from 416R stainless steel with a 1:10 right-hand twist and carries the same 4.30" profile as the factory slide so it seats and cycles without fitting or modification.

The stand-out feature is the Gold Titanium Nitride (TiN) finish - a high-grade PVD coating applied over the polished stainless body. The TiN layer hardens the outer surface for improved wear resistance, helps the bore and exterior shrug off carbon buildup, and gives the barrel its bold gold appearance that pairs cleanly with both factory and aftermarket P365-FUSE builds.

Up front, the barrel is threaded 1/2x28 for standard 9mm muzzle devices, compensators, and thread protectors. It installs as a true drop-in unit into the existing P365-FUSE slide assembly - no gunsmithing required - and ships with no sights, letting shooters keep their preferred iron or red-dot setup. Built in the True Precision tradition of precision-machined aftermarket components for Sig Sauer pistols, the TPP365FBXG offers a premium upgrade path for P365-FUSE owners looking to customize both function and finish.
