Xtech Tactical MTX Magazine Extender Features The Xtech Tactical MTX Magazine Extender fits the Smith and Wesson M&P Shield 9mm and Shield 9mm 2.0 adding two rounds of capacity to the factory 7 and 8 round magazines. A patented internal wall design keeps the extender s inner diameter consistent and smaller than the magazine tube itself which is what allows the custom engineered spring to maintain reliable feeding all the way to slide lock. The 8 round magazine configuration reuses the factory sleeve so the extender integrates cleanly without extra hardware. This combination of a purpose built spring and precise internal tolerances is what separates the MTX from generic extenders on the market. Installation is tool free and takes only seconds making the MTX practical for shooters who want more rounds on hand without sending a magazine out for gunsmithing. The extended floorplate adds textured gripping surface that improves control during recoil and speeds up reloads under pressure. Xtech Tactical notes the piece is made in the USA and is California compliant giving shooters in restrictive states a legal capacity boost. For a Shield 9mm owner who wants a few more rounds with the same reliable trigger reset the MTX Extender is a simple affordable upgrade for sale at GrabAGun.
