The HK P30L 9mm 5-Inch Threaded Replacement Barrel (H&K part no. 229792) is a factory-spec drop-in barrel for the Heckler & Koch P30L pistol. Cut to 5 inches and chambered in 9mm, it is threaded M13.5×1 left-hand to accept HK-pattern suppressor and muzzle device adapters. The left-hand thread direction matches HK’s factory convention, so standard HK thread protectors and adapters index correctly. Since this is a handgun barrel, the 16-inch federal rifle minimum simply does not apply here regardless of length.
