The SIG Sauer P320 Subcompact Barrel (brand part number BBLMODSC9) is a factory replacement barrel chambered in 9mm Luger and sized to the P320 Subcompact’s 3.6-inch slide length. SIG machines it from steel and finishes it in Black Nitride, matching the corrosion resistance and appearance of the factory original barrel. Because the P320’s fire control unit, not the barrel or slide, carries the pistol’s serial number, swapping this barrel is a straightforward job that doesn’t require gunsmith work. It’s a direct way to replace a worn factory barrel or return a P320 Subcompact to factory-spec dimensions.
