Whether you're running drills at the range, training for a competition, or preparing for duty use, extra ammunition on tap means fewer mag changes and more time focused on your shots.
Shield Arms engineered this extension with a user-friendly floor plate design that lets you access the spring and follower without removing the extension from the magazine body—a genuine convenience when you're maintaining your gear. The extension features index cuts on the body for a solid, indexed fit and is machined to work seamlessly with the factory spring. It's USA-made, fits most aftermarket flared mag wells, and carries a lifetime warranty backing the craftsmanship.
