The Tapco Tap22099 is a magazine extension designed to add five rounds of capacity to your Glock 19 or Glock 17. If you run a 9mm Glock for duty, sport shooting, or home defense, a mag extension is a straightforward way to squeeze more ammunition into your standard magazines without swapping to aftermarket tube. The Tap22099 extends your Glock 17 or 19 mag from its factory round count to five additional rounds—handy whether you're running drills at the range, competing in action sports, or just want that extra margin on your carry gun. Tapco's extension is molded black to match your magazines and frame.
Installation is simple: unload your magazine, remove the baseplate, and slide the extension onto the magazine body. The extension seats under the magazine catch just like the factory baseplate, so function and reliability depend on proper fitting and a clean magazine tube. Given the close tolerances of Glock mags, fit can be picky—some users report excellent results; others find their mags seat tightly or require a break-in period. Test it thoroughly before relying on it in any duty or defense role, and make sure your firearm's mag well and feeding geometry work smoothly with the added length and weight.
Magazine capacity regulations vary by state and locality—verify your local laws before purchase. This extension is compatible with OEM Glock 19 and Glock 17 magazines only; do not assume compatibility with third-party magazine bodies or other Glock models. Like any magazine accessory, longevity depends on quality of materials, frequency of use, and maintenance. Keep your magazines clean, inspect for wear, and replace baseplates or extensions if they become loose or damaged.
