This SIG Sauer factory replacement barrel (SIG part number BBL-229-9-T) upgrades or replaces the barrel on a P229 or P228, chambered in 9mm with a 3.9-inch threaded muzzle. The unusual 13.5×1 LH thread pitch lets shooters attach a suppressor or other muzzle device, and a knurled thread cap protects the threads when nothing is mounted. Like every SIG Sauer factory barrel, it is specially heat-treated for toughness and durability, giving P229/P228 owners a genuine factory path to a threaded pistol.
