Warne S&W M&P 9/40 Magazine Extension 9mm/40 S&W +3/+2 Black

The Warne S&W M&P 9/40 Magazine Extension is a black aluminum base extension for Smith & Wesson M&P 9/40 magazines. It is designed to add a longer grip surface to the magazine so the shooter has more to hold during reloads, and it is made for use with 9mm Luger and .40 S&W magazines in the M&P platform.

The extension adds capacity of up to three rounds in 9mm and two rounds in .40 S&W. Its ergonomic shape is intended to make insertion easier, and finger grooves allow the magazine to be stripped from the handgun when needed.

The part is listed for the Smith & Wesson M&P 9/40 platform only, and it is sold as a magazine accessory rather than a complete magazine.
