After leaving cookie crumbs around the world for months, Springfield Armory on Tuesday announced the Kuna large format pistol platform is available in the U.S. – and we have a full review.
Springfield Armory Kuna Review: The Kuna is a disruptive 9mm large-format pistol that brings roller-delayed blowback technology to a sub-$1,000 price point. While traditional PCCs rely on heavy bolts and stiff springs, the Kuna offers the ultra-smooth recoil impulse of an MP5 in a modern, modular package. In this review, we subject the Kuna to a 1,000-round torture test to see if it lives up to the hype as the new king of the budget-friendly PDW market.

9MM Roller-Delayed
Kuna (Base Model)
Features a monolithic aluminum upper and a Picatinny rail end plate for versatile custom brace mounting.
Designed by popular Croatian gunmaker HS Produkt, the Springfield Armory Kuna (Croatian for "Pine Marten," the national animal of that country) sub-gun first surfaced last October when it beat the top-shelf B&T APC40 and Steyr M40 for a contract with the PMESP, the Sao Paulo Military Police – the largest police force in Brazil. Chambered in .40 S&W, it also appeared at EnforceTac in Germany back in February with a promised 9mm variant inbound as well. The word was that the svelte little burp gun, using an advanced roller-locked system of operation, had been developed with international counter-terror teams in mind.
Now, it is available in a semi-auto pistol variant in the U.S., initially just in 9mm. It will be sold at launch in a standalone pistol variant (KN9069B) as well as a more deluxe version (KN9069B-FSA) sold with an installed Strike Industries side-folding stabilizing brace. The MSRP varies between $999 to $1,149 with the braced model running higher.
We have the latter option on hand for a review.
The overall length of the brace-equipped Springfield Armory Kuna is 24.5 inches with the brace deployed and a more compact 15.5 inches folded. The gun can be fired in either position. (All photos unless noted: Chris Eger/Guns.com)
For full disclosure, Springfield Armory provided this Kuna pistol for review purposes. All testing was done on this one gun, which has been under evaluation since January.

Features
The Kuna falls in line with the rest of Springfield's Croatian family tree, including the Hellion 5.56 NATO bullpup rifle, the Echelon pistol series, and the Hellcat micro-compact handgun.
The rollmarks show HS Produkt production in Croatia, along with Springfield's familiar ordnance wheel.
One thing immediately apparent in the ergonomics is that the Kuna's AR-pattern grip runs the company's familiar adaptive grip texture that has proved popular on the Echelon and Hellcat. Of note, the Kuna's grip has a built-in storage compartment.
It really is identical.
The magwell has a similar texture. Note that the bolt has a side-swappable folding charging handle.
The overall length is 24.5 inches with the brace deployed.
The Strike Industries FSA is a robust steel-hinged design that offers a ton of stability when engaged. The single-side folder design quickly deploys and easily collapses when not wanted – simply lift on the arm and fold to the left.
Note the sling band slot. The brace also has one QD point at the 6 o'clock facing position.
Should you want to remove the brace from the rear Picatinny block, it comes off simply with a T25 bit.
Without the brace, the Kuna loses about an inch in folded length and 11 ounces in weight.
With QD sling sockets on both sides of the monolithic upper receiver, the braceless Kuna is easily set up for use in the old sling-tension method, reminiscent of the 1980s British SAS.
With the brace installed along with a Vortex Crossfire red dot on a tall mount and a Streamlight Pro-Tac HP-X light, the Kuna easily fit inside a 5.11 Rush series 12 2.0 24L backpack, which only has an 18x11-inch main compartment. There was also plenty of room for mags, ear pro, and range snacks.
The barrel is threaded in a common thread pitch (1/2x28 TPI), and we fitted a SilencerCo Omega 36M suppressor. A modular can, the 36M is a modular, multi-caliber suppressor designed for rifles, pistols, and magnum calibers. The Kuna easily fits inside a milsurp ($20) M60 spare barrel bag without taking off the Omega.
The removable muzzle device incorporates top ports to help mitigate recoil. Sadly, it is not tri-lug, which would have been a solid bet. Note the folding, non-reciprocating charging handle.
The aluminum upper includes six M-LOK slots, two each at the 3-, 6-, and 9-o'clock positions. All NFA rules apply when using the bottom-facing slots concerning forward vert grips, but bipods are fine.
The steel rear sights take a page out of those used on the Springfield Armory Hellion. They are dual flip-ups for close-in fast acquisition and a peep aperture for long-range work.
The same can be said of the front sights.
Going past the installed sights, which are excellent and allow an 11-inch sight radius, the Kuna has an 8-inch top M1913 Pic rail for optics. We installed a Vortex Crossfire on an elevated mount for the length of our evaluation. It's tough to beat a nitrogen-purged (fogproof/waterproof) Crossfire for use on a PCC, as it has 11 intensity settings (2 NV) and a 50,000-hour battery life while only adding 4 ounces to the gun.
When it comes to controls, they are all easily manipulated and simple to operate. Here we have the two-position safety selector, push-button magazine release, and AR-style bolt release. The safety was pretty stiff at the beginning of the evaluation, but it smoothed out after a few dozen rotations.
They are mirrored on the right side for use by lefties, although the ejection port is fixed.
For taking a peek at the internals, the Kuna field strips easily by pulling out two captive disassembly pins, one in the rear of the upper and the other at the front pivot of the lower. Make sure the magazine is removed, the chamber is empty, and the safety selector is on "safe" beforehand.
Further breaking the Kuna down, pivot and slide off the Picatinny end cap, then carefully remove the recoil spring assembly.
And there you go.
The bolt then is easy to remove. It is an interesting design engineered to carve away reciprocating mass, which in turn cuts down on felt recoil by employing a roller to temporarily lock the bolt into battery, like the action on an HK MP5. This gives it a boost over more rowdy straight blowback designs such as the CZ Scorpion, most PCC AR-9 kits, or the KelTec SUB2000.
The lower is an injection-molded, glass-filled polymer design and includes the trigger group and surface controls.
Going past the basic field strip looked fun, but we didn't attempt it. (Graphics: Springfield Armory)
Trigger
The Kuna has a flat-faced aluminum trigger with a short travel, covering just under a third of an inch, until coming to a wall that broke clean at an average of 6.5 pounds. The reset was short and positive with an audible and tactile "click." It was easy to run fast, and it helped with accuracy.

Reliability
We put just over 1,000 rounds through the Kuna in testing, running the gun right out of the box with no additional treatment or preparation. We kind of abused the gun a bit, running it most of the time with a suppressor mounted and with an unrealistic variety of ammo. To elaborate on the "unrealistic," besides a host of factory-fresh ammo from Federal/CCI/Speer in 115-, 124-, 147-, and 150-grain weights, I also ran a bunch of downright dated Remington, UMC, Winchester, Wolf, Tula, Fiocchi, and Nosler rounds of assorted bullet weights and types.
Despite the funky diet, we found the gun to be utterly dependable.
Below is a typical 30-round suppressed run, using more than 20 different types of ammo in the same magazine.
The bulk of the ammo used in the review was provided by Federal, including 147-grain Syntech Training Match, 115-grain Syntech Range, 115-grain CCI Blazer brass, 150-grain Syntech Action Match, 124-grain Syntech Training Match, and 115-grain Train and Protect JHPs. It ran clean and proved both accurate and reliable.
The magazines, which favor those used by the SIG MPX, are proprietary to Springfield. Translucent polymer with steel lips, they proved tough in testing. While we hate proprietary mags, Springfield says these will only run $25 for extra mags, which is nice. Of note, we could usually squeeze 31 rounds in the magazines without affecting function.
Accuracy
The Kuna leads to easy practical accuracy – almost like a cheat code. Little wonder, as it has outstanding iron sights in two different formats with a long sight radius of 11 inches compared to a 2011's 8 inches. Added to this is a super solid stabilizing brace, smooth roller-delayed action, and a large AR-style pistol grip with good ergos.
It was almost too simple to zap Alphas on IPSC targets offhand out to 25 yards in a fairly rapid double cadence, especially with the Crossfire installed.
Moving to the bench, groups ran from 4 to 8 inches at 50 yards (keep in mind you are still using a 6-inch barrel here with a 2-MOA red dot). Switching to Federal Premium 147-grain Action Match, we were able to drop that down to repeatable five-shot groups in the 1.5-inch range.
The Kuna at 50 with 147-grain Federal Match, stabilized on sandbags at the bench in slow fire. The Crossfire is a 2-MOA red dot.

Pros & Cons
Pros
Springfield Kuna: The Verdict
What We Liked (Pros)
Value: Highly affordable price point for a roller-delayed 9mm.
Soft Shooting: Simple roller-delayed system offers superior recoil management.
Ergonomics: Fully ambidextrous controls with a reversible charging handle.
Out of the Box: Features a crisp trigger and excellent factory iron sights.
Suppression: Threaded barrel is suppressor-ready and cycles mixed ammo reliably.
Ready to Carry: Integrated QD sling sockets and a sturdy stabilizing brace.
The Trade-Offs (Cons)
Magazines: Uses proprietary mags; not compatible with Glock or MP5 patterns.
Aftermarket: Limited initial support for triggers, handguards, or specialized parts.
Conclusion
Nobody was looking for the Kuna to roll into 2025 and instantly turn heads. Well-made 9mm large-format handguns in the SMG/PCC style have been increasingly popular in recent years, and it is clear that the folks behind the Kuna did their homework and did it well. You get a smooth-shooting and reliable platform that allows easy use with suppressors, lights, and optics, for right around $1K. Taking notes from the Echelon, Hellcat, and Hellion when it comes to ergonomics and sights, Springfield is playing the hits here. It feels like a smoother and more updated version of the MP5K on the range.
The Kuna proved a sewing machine with a can installed, here seen with a SilencerCo Omega 36M.
About the closest competitor in the delayed blowback 9mm PCC space to the Kuna that isn't an MP5 is the Grand Power Stribog SP9 A3S, which is about $200 more.
The only complaint we can enumerate on the Kuna is that the mags are proprietary, as are most of the components other than the grip, which is an AR-15 pattern. While there is no support on the aftermarket for this gun, that will surely change so long as it remains in production.
And we bet that Springfield will soon be cranking them out to meet high demand.
