The M&P9C compact was introduced to give plainclothes officers and concealed carriers a shorter-grip, shorter-barrel M&P9 option. The 3.5-inch barrel and reduced grip height maintained compatibility with full-size M&P9 magazines when using an extended basepad. It was a popular off-duty choice for agencies that issued the full-size M&P9 as the primary duty gun.
