Preface
Last fall, a few other writers and I were invited to Geneseo, Illinois, to tour the Springfield facility and see some of their new products. As we walked through the 180000 square foot facility, I enjoyed seeing how streamlined their process was. With my background in Industrial maintenance, I enjoyed it a bit too much. Before we had finished the first section, I found myself lagging behind the group, trying to identify what function each machine served in the production line. Larry, one of their engineers, was kind enough to quench my intrigue and explain some of the processes in more detail.
We talked about the best uses of EDM (Electrical Discharge Machining), the simplicity of their parkerizing process, his experience with the robotic arms they use to apply cerakote, and much more.
After the tour, we drove just out of town to Springfield’s private range. That day, I was one of the first to shoot the compact Prodigy models, the Echelon 4.0C, and the Kuna. In addition to the new stuff, we also got to shoot a variety of M1As, including one setup to fire rifle grenades. Lobbing those practice grenades down range was some serious fun.
Even with all the variety of guns I shot that day, the Kuna was the one I requested to review personally. At the time of writing, I had my loaner Kuna for six weeks and put about four hundred rounds through it. This is not a full durability test, but I have gotten a good feel for the pistol’s performance.

Initial Impressions of the Kuna
Honestly, my initial impression of the Kuna was not great. As it was being passed around Springfield’s training room, I thought, “The market does not need another generic sub gun”. Almost as if they had heard my thought, the Springfield rep began detailing every feature that sets the Kuna apart. By the time we finished shooting, my initial impression had been turned on its head.
General Overview
Starting at the muzzle, this pistol comes with a nice multi-port brake. The six-inch hammer forged barrel is threaded 1/2X28”. I was happy with the stock muzzle device, but I decided to swap it for a single-port ASR brake so I could run my suppressor.
The barrel is shrouded by a slim M-LOK handguard that stops just short of the muzzle. I use one of the slots to run my Streamlight ProTac 1L. This light is not the most powerful, but its compact size fits this pistol well.
On the top portion of the handguard, you will find the charging handle. It is non-reciprocating and springs closed when not in use to stay out of the way. Mine was originally on the left side, but I swapped it to the right after mounting the light to keep it clear of any obstructions. Moving it was incredibly simple and only took me a minute.
Sights and Optics
Still focusing on the upper portion of the pistol, I would like to highlight the integrated flip-up sights. Both front and rear sights are built into the weapon and fold flat out of the way when not in use. They are very sturdy and feature adjustments for both windage and elevation. My main complaint is that they are too short. I am running an absolute cowitness height red dot, but that sits too high to co-witness with the sights. I could low mount a red dot, but then I can’t use a magnifier.
I suppose it would be a good idea to mount the optic as low as possible. This will mitigate any height-over-bore issues from the low barrel position.
The Brace
With the Kuna, you have the option to get it either braced or unbraced. The braced model comes with a Strike Industries FSA brace. This is my first time using an FSA, and I am a fan. The hinge mechanism is sturdy and offers the right amount of resistance to keep it folded. It folds easily and does not add much to the pistol’s width.
One disadvantage of the slim design is that it may not be very comfortable to shoot with the brace shouldered. That’s common for many braces, but still worth mentioning. Just be sure to talk to your wife before heading to the range, “No, that’s not a hickie on my collarbone; I swear it’s from the brace”.
Roller Delayed
The prime feature that sets the Kuna apart from other pistols in its price range is its roller-delayed operating system. The bolt integrates a spring-loaded roller mechanism that locks with the receiver as the bolt closes. When the round is fired, the recoil first unlocks the roller before it acts on the bolt to cycle the action. Thanks to this simple yet precise mechanical system, the Kuna displays a significantly quicker recoil impulse than blowback-operated firearms.
The roller delay action also improves suppressor effectiveness by reducing the amount of ejection port flash and gas blowback. Other than a 22 pistol, this is probably my favorite gun to shoot suppressed.
Kuna Controls
Considerable thought was put into the design of the controls. The bolt release, bolt catch, mag release, and safety are all ambidextrous. And more than just ambidexterous, they are effective. My trigger finger can manipulate the bolt catch, bolt release, and mag release all without shifting my grip. This makes clearing the pistol, locking the bolt back, and reloading smooth and fast.
The Kuna’s trigger is a bit tricky to describe. It breaks reliably at five pounds, which isn’t too heavy, but it feels like mush. The wall is deep and uneven, with no real sign of when you’ll break through. As I said, it’s usable, but I wish it had a cleaner break.
A Practical Use Case
While there is nothing wrong with buying a gun just for fun at the range, I always like to think about what practical application it fills. While technically compact enough to fill the role of a bag gun, I think that role is better filled by something smaller like a FLUX Raider. I have carried it in a backpack a few times, but it takes up the entire bag and isn’t so quick to deploy. Plus, there are only thirty round mags available for the Kuna. Maybe when they come out with a more compact magazine, I will reconsider this position.
I see the Kuna best fitting the role of a bedside gun or truck gun. Its small size makes it great for working around the tight spaces of a home or vehicle, plus the folding stock makes it easy to store out of sight.
At the Range With the Kuna
As I already mentioned, this gun is loads of fun to shoot, especially suppressed. 9mm is still one of the cheapest center-fire cartridges, so you can blaze away at the range or put in a substantial amount of training without breaking the bank.

I have shot a variety of ammo, both suppressed and unsuppressed, without a single malfunction. I’ll attribute this to a well-designed action but also a well-designed magazine. I questioned why they decided to use a proprietary mag, and Springfield said they simply weren’t happy with the durability/reliability of the available options. From my limited experience, it seems they achieved their goal of producing a reliable magazine. The gun has two mags, and I’m told spares will run around $25.
Final Thoughts On the Kuna
By now, it should be obvious that I am a fan of the Kuna, and the price makes it even better. After handling it for the first time, I fully expected an MSRP over $2000. When they said their goal was to bring the Kuna to market with a brace for under $1200, I was a bit unsure if they would hold to it.
Now we have the final prices, and I am happy to say they met their goal. The Kuna, including the brace, is $1149, and the unbraced version is $999. For those in the market for a compact sub-gun, the Kuna has proven itself to be a very competitive option. Be sure to check out the Springfield website for more info on the Kuna and to learn the interesting origin of its name.

Any idea if this will be available from Springfield as a SBR with the original folding stock and tri-lug barrel? That would be the ultimate home protection rifle.
Nice. I want a carbine version with a 16 inch barrel and an actual folding stock. Stay safe. j
Just wondering how this stacks up against a GP Stribog. My first glance impression was that they copied the Stribog and after reading your review I’m more convinced that that’s what they’re doing. Guess I’ll have to check one out & find out.
Hello, what was your range distance when shooting groups with the Kuna? What is the distance which the Kuna can accurately be shot? Thank you!
Seems odd they didn’t make fifteen or twenty round mags available initially along with the 30’s since one of its main markets in the US and worldwide is as a PDW.
basically they photocopied a MP5 moved the bolt release to shooting hand instead of your stabilizer hand, added a proprietary mag and called it a Kuna.
It is worth noting that the Kuna, as shown here, will get you charged with possession of an unregistered short barrel rifle if you aren’t a member of one of the organizations that have sued to stop the ATF’s rule on pistol braces. None of the cases against the ATF pistol brace rule have been settled, so the ATF position remains that the rule is valid and still in effect. They are blocked from enforcing the rule by separate injunctions issued in each of the cases, but those injunctions only apply to the organizations that sued the ATF. Taylor Taranto is currently still facing charges for possession of an unregistered SBR for having bought a braced CZ Scorpion EVO 3 without being a member of any of the organizations covered by the injunctions.
As of today, the SBR charge against Taylor Taranto has been dropped. Happened a few days ago and the ATF admitted it had been filed mistakenly.
Braced pistols have been legal since June 13, 2024 when the Thompson v. ATF ruling and Johnson v. ATF which reaffirmed the judgement which said the ATF’s ruling was “arbitrary and capricious” and thus vacated the ATF’s ruling on braces nationwide and is not dependent on being a member of a particular group.
Yes, the SBR charge was dropped and they are just charging him for possession of an unregistered pistol. Originally they had charged him with possession of BOTH and unregistered SBR and an unregistered pistol for the same gun. Obviously the gun cannot be both a pistol and an SBR so they had to drop one of the charges. The US Attorney took the easier path, but that doesn’t mean that all braces are always legal.
The legal cases you mentioned were about the ATF’s new Pistol Brace RULE with its arcane “factor” system that was intended to outlaw nearly all braces without blatantly saying so. The courts threw out the rule on the basis of not meeting the standards of the Administrative Procedures Act. The rule with its factor system is out, but that does not change the law about short barrel rifles. You can still be charged with possession of an SBR if the ATF and DOJ think they can prove that what you call a “brace” was actually a “stock.”

A Member? Since when did the 2nd recognize any membership other being a U.S. Citizen??? Are you saying being a member of those organizations means you won’t be charged? That’s a blatant violation of the 14th Amendment’s equal protection clause.
‘rules for thee but none for me’ ISN’T in the Constitution nor it’s Bill Of Rights.
I find it all very confusing since I live in Illinois where the firearm is produced and could never be a plaintiff in either case. Under Pritzker Illinois has threatened citizens that were party to a lawsuit with arrest if they purchased a firearm while protected by an injunction. I guess the USSC has no problem with ‘justice delayed.’
And the defendant in the pistol brace cases, would that be AT Pam Bondi? I trust her a little less as each day goes by. Yeah, she done some good things and talks an OK game. Here is what would help bring back some trust of Bondi, drop the controversial Dettelbach cases, he is an idiot. Investigate the federal cases that involved needless home raids and cost human lives, (Brian Malinowski, Craig Robertson). Bring charges where the feds were criminally negligent.
Admit that the most disturbing case files of Epstein, the JFK assassination, 9/11 et cetera will never be released for the unwashed masses to view.
The proof that the most telling evidence will never be released is exemplified in the JFK assassination. Just seconds after JFK was murdered, federal agents identified every person with a camera, approached and seized almost every camera at the crime scene. Today that time period where federal agents were able to calmly confiscate the ‘evidence’ would now be called an ‘active shooter.’ The feds were unconcerned with being shot, why? Where is all that ‘evidence’ that the feds confiscated from those filming the event?
I am afraid Bondi will never put herself at cross purposes with the fake law and order of the deep state. She is looking more and more like Sessions and Barr.
