This Smith and Wesson slide assembly is built for the M&P9 and measures 4.2 inches, set up for an ACRO optic. Replacing a slide is one way to upgrade an M&P9 to an optics-ready configuration, and the ACRO is a popular enclosed-emitter red dot designed for duty-grade durability. Slide assemblies from the manufacturer help ensure proper fit and function with the frame and parts. Confirm that the slide matches your pistol's model and generation before ordering, and perform a thorough function check after installation.
