Smith & Wesson®'s popular M&P Shield Semi-Auto Pistol operates with a striker-fired action, eliminating any external hammer to catch on clothing when this handgun is carried concealed. The thin 1" profile aids with concealment. The operation is based on a polymer frame and coated stainless steel action. Other features of the S&W M&P Shield pistol are white dot rear and front sights, 2-piece trigger, textured grip, extended magazine that increases grip surface, and rounded features to make the handgun more concealed carry oriented.
