The MTX +5 Magazine Extension is built specifically for Smith & Wesson M&P9 and M&P9 2.0 full-size pistols. If you're running standard factory magazines, this extension gives you five additional rounds without requiring any special tools or gunsmith work. It installs in seconds and pairs directly with your factory magazine body and follower—you're just swapping out the basepad and adding the included spring.
What makes this extension different is the patented design. Unlike other extensions on the market, the MTX uses a consistent internal wall throughout the extender that's actually smaller than your magazine tube. This eliminates catch points that can snag rounds during feeding, so you get flawless magazine performance whether you're training, competing, or carrying. The spring included with this kit was engineered specifically for the M&P9 line, which means you get reliable last-round slide lock functionality. Drop tests confirm the extension holds up to repeated impacts without failure.
Built from durable polymer with an impact-resistant finish, the basepad has a lip on the front that acts as an over-insertion stop. This protects your pistol frame during high-stress reloads when you're running drills. The extension adds real-world capacity without making the magazine bulky—you get a manageable package that works for both daily carry and range use. Whether you're looking to run extra rounds in competition or just want more ammo between reloads, this extension delivers the capacity and reliability that comes from a purpose-built design.
Yes, the MTX extension is designed specifically for factory M&P9 and M&P9 2.0 magazines. You simply remove the factory basepad and follower, keep the magazine tube and follower, then attach the MTX extension with the included spring. It uses your factory magazine body, so there's no compatibility issue.
No tools required. The MTX extension is designed for tool-free installation that takes just seconds. You swap out the factory floorplate for the MTX basepad and add the included spring—that's it.
