This is the Springfield Armory Kuna 9mm 30-round magazine. 

Whether you’re in need of some replacements or a couple of extra magazines for your Springfield Armory Kuna, you’ve found them!

Designed specifically for the Kuna, these impact-resistant translucent polymer magazines are an exact fit and feature steel-reinforced feed lips for superior durability. Inside, anti-tilt polymer followers and high-quality steel springs provide the reliability to match. Thanks to the polymer construction, these remain lightweight and are perfect for a run-and-gun-type firearm like the Kuna.

You’ll also find side-facing round count indicators to help you assess your remaining capacity. There isn’t much left to be desired, except for maybe a few more rounds!

Being that these are proprietary, they may sell out quickly. We recommend grabbing a couple while you still can!
