XTech Tactical Magazine Extension for S&W Shield +2 9mm Luger

The XTech Tactical Magazine Extension is compatible with factory magazines and installs in seconds. Unlike other shield mag extensions on the market, the Patented design permits for a consistent internal wall throughout the extender, which is smaller than the M&P magazine tube. The included spring was engineered specifically for the M&P Shield 9mm to allow for unmatched reliability and last round slide hold open. For use with the .40 S&W the extender uses the factory spring. XTech Tactical's MTX
