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 line of extenders are simply unmatched for reliability, ease of installation, and durability!
