The ProMag SPR-A23 Springfield Armory Kuna 9MM Extended Magazine delivers a generous 40-round capacity in a slim, curved profile designed specifically for the Kuna’s roller-delayed 9MM action. Built around a rugged DuPont Zytel polymer body, this magazine is engineered for long-term durability while keeping weight to a minimum for extended range sessions.

This extended magazine is ideal for shooters who want more time shooting and less time reloading, whether they are practicing fundamentals, running drills, or setting up a competition-style course. The heat-treated chrome silicon spring and injection-molded follower work together to promote smooth, consistent feeding from the first round to the last. It is a practical upgrade for range training, competition, and home-defense setups, backed by ProMag’s reputation for innovative aftermarket magazines.
