The Smith & Wesson Threaded Barrel (brand part no. 14401) is a factory-spec, 4.625-inch 9mm Luger barrel threaded 1/2-28, built to drop directly into an M&P M2.0 pistol. Smith & Wesson machines this barrel to the same tolerances used on the original factory M2.0 barrel and finishes it in black to match the pistol, adding external threading so a compatible muzzle device or suppressor can be mounted. At roughly 5 ounces, it will not fit the earlier M&P M1.0 generation.
