Springfield Armory Kuna FSA 9mm — 6.13" Barrel, 30-Round
The Kuna is Springfield Armory's roller-delayed 9mm pistol, built around a monolithic 7075-T6 aluminum upper and a lightweight polymer lower. The roller-delayed blowback system meaningfully reduces felt recoil and improves control over a standard blowback pistol-caliber platform, making follow-up shots faster and tighter.
This one is in stock now and moving fast — the Kuna has been in high demand since release, and availability on this configuration is limited.

Frequently Asked Questions
Does the FSA folding brace require an ATF tax stamp?
As sold, this configuration is classified and shipped in compliance with current ATF regulations. Brace and pistol-stabilizing-device rules have changed multiple times in recent years — confirm current regulations in your state before purchase, and contact us if you have questions about this specific configuration's classification.
What's the difference between the Kuna's roller-delayed system and a standard blowback 9mm pistol?
A roller-delayed blowback system uses rollers to briefly delay the slide's rearward movement under pressure, rather than relying purely on the weight of the slide and recoil spring like a standard blowback design. This meaningfully reduces felt recoil and muzzle rise, making follow-up shots faster and more controllable.
How many magazines are included?
Two 30-round detachable magazines with reinforced metal feed lips ship with every Kuna FSA.
Can the FSA brace be removed or swapped?
The brace mounts to an integrated Picatinny receiver end plate, so it can be removed, though doing so may affect the pistol's legal classification depending on your state and intended configuration. Consult current ATF guidance or contact us before modifying.
