The Springfield Armory Kuna is a compact 9mm Luger pistol built around a roller-delayed blowback action, designed as a PDW-style platform with a pistol brace rather than a stock. It has a 6.12-inch cold hammer-forged barrel and an integral M-Lok handguard, and ships with two 10-round magazines. The monolithic upper receiver is 7075 T6 aluminum with a Type III hardcoat anodized finish.

The Kuna in 9mm draws a lot of comparisons to other roller-delayed PDW pistols, and owners generally describe the action as smooth once broken in, with less felt recoil than a straight blowback gun of similar size. A recurring complaint in this class is that reliability during the first few range trips can be inconsistent until the gun wears in, so some owners recommend a proper break-in before relying on it.

Because it ships with a brace rather than a stock, most owners find the Kuna easiest to run shouldered for stability, and the ambidextrous controls get consistent praise from left-handed shooters. A few owners mention the grip and control layout takes some getting used to compared to a standard AR-pattern pistol.

On value, buyers comparing the Kuna to other 9mm PDW-style pistols like that the handguard uses a common accessory standard, which keeps rail and light options open. Some feel the price sits high relative to a basic AR-pattern pistol caliber build, while others think the roller-delayed action and included brace justify the difference.
