ProMag Springfield Armory Kuna 9mm Magazine – 40-Round – Black Polymer – SPR-A23
The ProMag SPR-A23 (708279017377) is a high-capacity 40-round extended magazine specifically designed for the Springfield Armory® Kuna™ 9mm series. Released for the 2026 market, the Kuna is a roller-delayed blowback pistol-caliber carbine (PCC) developed in partnership with Croatia's HS Produkt. The SPR-A23 provides a massive increase in firepower over the factory 30-round magazines, making it an ideal choice for home defense and extended range sessions. Constructed from ProMag's proprietary DuPont™ Zytel® based polymer, this magazine offers exceptional impact resistance and thermal stability, ensuring it remains reliable even during high-volume strings of fire common with PCC platforms.
Internally, the SPR-A23 is built to professional standards, featuring a magazine spring formed from heat-treated chrome silicon wire. This high-tensile spring provides consistent upward pressure to the injection-molded follower, ensuring smooth, reliable feeding of 9mm Luger cartridges. The magazine's straight-body design is optimized for the Kuna's dual ambidextrous mag release system, and the polymer construction ensures a lightweight profile that doesn't upset the balance of the 6-inch barreled PCC. Like all ProMag products, the SPR-A23 is Made in the USA and backed by a lifetime warranty, providing a rugged and affordable high-capacity solution for the innovative Kuna platform.
