The Sig Sauer P320 Full-Size 9mm threaded barrel measures 5.5″ and comes factory heat-treated for durability. It features a 1/2-28 RH thread configuration and is compatible only with non-loaded chamber indicator slides and pistols. This is an official factory replacement barrel for the P320 platform.
Installation is straightforward: ensure the firearm is unloaded, remove the slide from the receiver and grip module, then slide out the existing barrel. A thread protector cap is included. Use this barrel to attach a suppressor or muzzle device to your P320 Full-Size.
