Springfield Armory Kuna Features The Kuna pistol-carbine uses a cold hammer-forged steel barrel and gas-operated action to maintain smooth cycling and reduced recoil. A multi-port brake helps manage muzzle rise and the flat-face trigger promotes consistent shot release. These features make the 40 S&W PDW a strong option for shooters wanting compact control with reliable ballistic performance. Its Strike Industries FSA pistol brace adds a stabilizing rear point of contact improving comfort and handling during extended firing. The M-LOK handguard and full Picatinny rail receiver provide broad accessory and optic compatibility while ambidextrous safety controls support adaptable operation. With an AR-style grip two included 30-round magazines and a rugged anodized receiver the Kuna delivers a reinforced PDW layout ready for practical defensive roles.
