The Smith & Wesson Replacement Barrel (brand part no. 14461) is a factory-spec, 4.25-inch 9mm Luger barrel built to drop directly into an M&P M2.0 pistol with a 4.25-inch slide. Smith & Wesson machines this barrel to the same tolerances used on the original factory M2.0 barrel, finished in black to match the pistol. It fits M2.0-generation Shields and full-size M2.0 pistols sharing this slide length, but it will not fit the earlier M1.0 generation.
