The Springfield Armory Kuna .40 S&W Pistol with Brace

The Springfield Armory Kuna .40 S&W with Strike Industries FSA Brace (KN90640B-FSA) brings heavy-hitting ballistic performance to Springfield's high-performance, compact PDW platform. Built around an advanced roller-delayed operating system, this configuration effectively mitigates felt recoil and muzzle rise, providing exceptionally flat tracking and rapid-fire control in a powerful cartridge.

Chambered in .40 S&W, the Kuna features a rigid monolithic aluminum upper receiver paired with an injection-molded glass-filled polymer lower. It sports a cold radial hammer-forged 6.125-inch threaded barrel with a multi-port muzzle brake, hybrid flip-up iron sights, a full-length top Picatinny optics rail, a reversible non-reciprocating charging handle, a factory-mounted Strike Industries FSA side-folding stabilizing brace, and high-capacity 30-round translucent magazines.

One 30-round magazine is included.
