Hot on the scene is the new Springfield Armory Kuna 9mm pistol! This roller-delayed, little wonder looks to make its mark on the firearm scene as a strong contender as a PDW (personal defense weapon).
The gold standard for a roller-delayed gas system is the Heckler& Koch MP5, or the nearest semi-auto equivalent that is available in the United States, the H&K SP5.
Does the new Springfield Kuna 9mm have what it takes to dethrone the it? Let’s run through the gauntlet to see!
Build Quality & Features: 9mm Kuna Pistol Delivers Affordability Without Compromise
Springfield Armory does a lot of things well in the build-out of this roller-delayed pistol. For starters, their barrel is cold radial hammer forged, which simply produces a better barrel: greater accuracy for a longer duration of your ownership. There is also the monolithic, forged upper receiver that eliminates the stacking of tolerances in other multi-piece upper receivers, a design philosophy consistent with what we’ve come to expect from Armory Life features and insights.

Where To Buy
Moving through the rest of the spec list, you simply see a lot of modern touches in the Kuna’s design. A Picatinny receiver end plate makes for easy mounting of accessories like braces, and stocks – if you go the SBR route. There are also a bevy of ambidextrous kuna features and even a standardized AR pattern pistol grip giving you an abundance of options.

At the time of this announcement, Springfield Armory has 2 versions of the Kuna 9mm model: one with and without a brace. The Strike Industries FSA Brace equipped version we’re checking out today has an MSRP of $1,149 making it an astounding $2,240 cheaper than an H&K SP5.
Performance & Reliability: Does it have What it Takes?
To test the Kuna pistol model, I headed to Josh Froelich’s F5 Range in Minnesota. While there, I put a healthy varying diet of ammo that included full metal jacket (FMJ) range ammo as well as some defensive hollow-points (HP). Roughly 500 rounds in a single range session while shooting both suppressed and un-suppressed.
- Federal Gold Medal Action Pistol 9mm 147 Grain | SKU: GM9AP1 | MSRP $32.99
- Remington UMC 9mm 115 Grain FMJ | SKU 23728 | MSRP $26.99
- Federal HST 9mm 124 Grain HP | SKU P9HST1S | MSRP $39.99
With some different grain weights and bullet profiles, the Kuna chewed through this meal no problem. On a different range day, I fired some fistfuls of mystery ammo out of a 9mm range bucket of mine and it devoured that ammo as well. The Kuna is not a picky eater and ran flawlessly during testing.
Accuracy & Silencers: Can It Hit its Mark?
Being the Kuna is a compact, defensive firearm, we definitely wanted to test it with a silencer. The can deployed for this review was one from JK Armament which could attach to the Kuna’s standardized 1/2″ x 28 TPI threaded muzzle.
During live fire, I spent all of my time within 50 yards or less on steel. With the Kuna 9mm pistol un-suppressed, it was incredibly accurate. I could mag dump onto silhouette steel never missing a single round. Attempting more challenging feats like hitting 5″ steel gongs at 50 yards or less proved not to be difficult at all either. For a PDW, this thing had point-and-hit accuracy. I was calling my shots all day long.
Adding the JK 105 CCX silencer had no point-of-impact shift or change in the accuracy of the Kuna. The advanced roller-delayed gas system still cycled perfectly, eating ammo, and yeeting cases across the range as one would expect.
Close Quarters: How Good is it in Tight Spaces?
As a PDW, the Kuna is incredibly compact (surprise, surprise). So, I opted to add a Strike Industries Bikini Hand Stop to keep my hand on the very small forearm area and to not accidentally extend to far touch a burning hot silencer or the screaming Multi-Port Muzzle Brake.
Whether I was sprinting around a mock pistol stage or attempting to do vehicle work – suppressed or un-suppressed – the Kuna’s form factor is incredibly easy to wield and manipulate in tight spaces.
Moreover, whipping out the brace from a folded position is easy once you get the hang of it.
In the case of self-defense, what often determines a favorable outcome for you, protecting yourself, is being the 1st one to place a lethal shot against a threat.
What this boils down to is the ability to get your guns in the fight and to acquire a fast, proper sight alignment to allow for that to happen. All of which I found to be easy with the Kuna.
Room for Improvement
I speak very highly of the Kuna pistols. So, where can it do better? What aspects did it fall short? From front to back, this PDW runs amazingly well and performs far outside its price point of $1,149. The one element that Springfield should look to improve is the lack of a hand stop. The forearm is such a small area to grip, and it places your hand suspiciously close to the muzzle, a design oversight not often seen in full-size rifles.
- Hand Stop – Add a hand stop for better dexterity and safety while handling.
While the mag well area is textured for gripping, I have never liked gripping the mag well of any platform as it makes you too “choked up” on the firearm. A simple $10 hand stop like the one I used from Strike Industries is all you need.
Final Verdict: BEST Roller-Delayed PDW?
For only $1,149 at full retail, the Springfield Armory Kuna is the best roller-delayed PDW on the market today.
In the month and half of testing I’ve conducted leading up to the announcement of this firearm, the Kuna has proven itself to reliable, accurate, fast to deploy, and affordable. All you need to finish off this PDW is to add your favorite red dot, a hand stop, and a silencer if you own one.
The PDW market isn’t known for being affordable or wholly reliable to be honest. Many manufacturers have this “race to be the smallest” or “most compact,” and this inevitably affects the functioning and reliability of those firearms all at the cost of being able to say something is tiny. The Springfield Kuna has thread the needle of accomplishing reliability along with a compact footprint.
If you’ve been dying to add a roller-delayed firearm and/or PDW into your life, this is it. The Kuna pistol is going to be the talk of 2025. Mark my words.
Personally I have a lot of PCC’s, but I’m always open to getting some more, this looks interesting.
Comes with 2 – 30 round magazines
Are these only available through SA, or will other mags fit it. They look almost like Thril or Sig MPX magazines
Other than that its a nice looking weapon.
Its a new weapon the aftermarkets haven’t gotten their hands on the mags yet. Give them six months. Be advised the cheapest made and least durable will be the first to hit the aftermarket. IMHO
Unless I missed it, this write-up doesn’t discuss the type of magazines it takes which is strange, but whatever. They are proprietary and will run around $25.00.
Other companies do sell the Kuna magazine. However it’s only this magazine since it’s made for the kuna only. They all sell for $25, but everyone is out of stock
I’d buy it from HS Product🙄
bingo bongo.
How much pain in theass paperwork is required to own one?
Here in NY ……..need to be a police officer, over in NH standard for pistol purchase.
Depends on your state. I have a LTC in Texas so was a pretty quick purchase. Like the previous remark, would be a standard pistol purchase and you will to decide if you want the brace already on it. I chose no brace so I could put one I like
Seconds on the mag issue, if its proprietary to this firearm its a limitation and normally a higher cost factor. It mag is common with other pistol platforms that’s a plus if you carry that other sidearm. This in turn may be after market available. I’m underwhelmed by the six inch barrel length. Eight would have provided greater balistics dividend over a four(+/-) holstered carry pistol that can use 30 round mags too and preform the same duties. There’s more grip area (and bulk) than a standard pistol but a 8 or 8.5 inch barrel would make a significant improvement.
You probably mean “roller-delayed blowback”. No gas is tapped from the barrel in a MP5.
Also, no mention of the Stribog, using an identical operating system right down to the backwards / misunderstood BCG mass distribution (and cheaper).
Pretty cool.
Given that the ATF/DOJ is still prosecuting new “brace cases”, I’d pass on the brace and go straight to SBRing this.
those that are able to should.
A – it’s Springfield. Never forget.
B – CMMG has had roller-delayed (and now radial delayed) blowback for years in an AR platform (yeah, a few proprietary parts, but…).
Having a traditional heavy-bolt/buffer 9mm PCC and a CMMG radial-delayed 45ACP with standard H2 buffer, they are similar in overall weight, similar soft-shooting. The CMMG takes glock mags, so ubiquitous. Build-your own CMMG is about 1k.
tip down carry is annoying, but i see it’s not reconfigurable.
How is this any different than a Stribog?
Would love to see it run side by side an Extar EP9 at about half the cost.
IMO The brace definitely needs design modification. The brace release is difficult to work, and a length adjustable brace is definitely needed. I hope aftermarket manufacturers read this.
I know a lot of people don’t agree, but I really think they should import the .40 S&W version too.
The caliber isn’t dead, despite what people think. And the market has a .40 S&W PCC shaped hole in it.
I picked up my Kuna yesterday. The man at the gun shop had never seen one, and was impressed.
I have a collection of 9mm PCC’S, including an Extar EP-9, but this one is special. It screams quality!
I can’t wait to shoot it.
