The Sig Sauer replacement barrel for the P229 (brand part no. BBL-229-1-9-T) is a factory-correct 9mm Luger barrel built for the E2 grip-style P229, measuring 3.9 inches with a threaded muzzle for a suppressor or muzzle device. Each barrel is specially heat-treated for toughness and durability, giving P229 owners a direct swap for a worn factory barrel or a straightforward path to adding a threaded option to a pistol that didn’t ship with one. Rifled with a 1:10-inch twist rate, it matches Sig Sauer’s own factory specification for reliable feeding and accuracy.
