Product Description

    Smith & Wesson M&P9 Full-Size 9mm, First-Generation, 4.25" Barrel, Black Melonite, 17+1

    This first-generation Smith & Wesson M&P9 stands out with its original fish-scale rear serrations, extended beavertail, and no external thumb safety. It features a 4.25-inch Melonite-treated stainless steel barrel, steel 3-dot dovetailed sights, and a 17+1 capacity. The bore is rated excellent, and the platform includes ambidextrous and reversible controls along with a sear-deactivation lever for tool-assisted disassembly without pulling the trigger.

    What’s Included
    • One 17-round steel double-stack magazine with witness holes (compatible with S&W M&P9)

    The pistol reflects the early M&P design, identifiable by its fish-scale rear slide serrations and extended beavertail. It is a full-size, striker-fired 9mm with a hinged trigger, 17+1 capacity, and an ambidextrous slide stop with a reversible magazine release. This example has no external thumb safety, aligning with common duty-ready configurations of the period.

    Construction emphasizes durability with a Melonite-treated stainless steel 4.25-inch barrel, a Black Melonite-finished slide, and a black polymer frame. The interchangeable backstrap grip system allows the shooter to fit the frame to their hand size.

    Sight regulation comes via steel three-dot sights that are dovetailed into the slide, with a rear sight set screw for secure retention. Up front, the integral three-slot 1913/Picatinny rail supports mounting of compatible weapon lights or accessories as needed.

    Practical safety features include a trigger safety, a loaded-chamber viewport, and a sear-deactivation lever that enables field-stripping without pulling the trigger. The right side of the slide is factory-marked "CAUTION - CAPABLE OF FIRING WITH MAGAZINE REMOVED."
