Scandium Alloy Frame
Stainless Steel Cylinder
Smith & Wesson's unique scandium alloy high strength frames allow for the lightest revolvers capable of firing .357 S&W Magnum rounds. The M&P340 has a unique matte-black frame with a stainless steel cylinder. Even with a corrosion resistant steel barrel liner to improve durability and accuracy, the M&P340 weighs less than a pound. The M&P340's hammer shroud helps shooters avoid annoying hammer snags.
