Sig Sauer P320 Threaded Barrel Features The Sig Sauer P320 Threaded Barrel is a factory-spec 4.60 replacement barrel chambered in 9mm compatible with the P320 Compact Carry and XCARRY platforms that include a loaded chamber indicator slide as well as any P320 designed to accept a 3.9 non-threaded barrel for a precise drop-in fit without modification or gunsmithing. The 1/2x28 thread pitch is the industry standard for 9mm pistol barrels ensuring broad compatibility with a wide range of compensators and suppressors from major manufacturers. Specially heat-treated for toughness and durability this barrel delivers the factory-level performance and longevity P320 owners expect. The P320 9mm factory threaded barrel features a black Nitron finish that provides superior corrosion resistance and surface hardness through sustained carry and range use and the loaded chamber indicator provides tactile and visual confirmation of a chambered round during administrative handling. The included thread protector keeps muzzle threads protected when running without a suppressor or muzzle device. Whether adding suppressor capability to an existing P320 or replacing a worn barrel this is the correct factory-spec solution.
