The Xtech Tactical MTX Magazine Extension adds five rounds to your M&P9 or M&P9 2.0 magazine without the bulk or reliability concerns of cheaper aftermarket options. If you carry, compete, or train with a Smith & Wesson M&P9, this +5 extender is a straightforward way to boost capacity while keeping your setup nimble. The black finish matches factory M&P furniture, and installation takes seconds—no gunsmithing required.
What sets the MTX apart is its engineering: the patented internal design maintains consistent wall thickness throughout the extender body, staying smaller than the magazine tube itself. This isn't just about fitting; it's about feeding reliably under pressure. The spring inside was tuned specifically for the M&P9 platform, so you get the same last-round slide lock-back behavior as factory magazines—critical whether you're reloading at the range or in a defensive situation.
The MTX works with factory M&P9 and M&P9 2.0 magazines, so you're not locked into buying proprietary gear. Drop it onto your existing mags and you're done. For shooters who want more rounds in the same footprint without sacrificing reliability or ease of use, this extension delivers.

| Fits | M&P9, M&P9 2.0 full-size magazines |

Installation takes seconds and requires no tools or gunsmithing. You're ready to shoot right out of the box.
The patented internal design maintains a consistent wall thickness throughout the extender body, which is smaller than the magazine tube itself. This engineering improves reliability and durability compared to other aftermarket options.
