Xtech Tactical builds the MTX extension (part no. XT3015601) to add capacity to factory M&P Shield 9mm magazines, adding 2 rounds to both the factory 7- and 8-round magazines when used with the Shield 9mm and 9mm 2.0. It ships with a custom-engineered spring and uses the factory sleeve when paired with the 8-round magazine, and it’s built with optimal ergonomics and texture to aid recoil control during a string of fire. It is not compatible with the Shield 9mm EZ, and on the .40 S&W 1.0 and 2.0 the factory spring must be retained (adding only 1 round on .40 S&W). For Xtech Tactical owners of an M&P Shield, this magazine extension adds real capacity without buying a whole new magazine.
