7.5 FK Field Pistol from BRNO Defense

Recently shown off at the IWA tradeshow over in Germany, BRNO Defense has introduced their 7.5 FK BRNE Combat Field Pistol. Built around a proprietary caliber, the handgun is designed for military, law enforcement, and government personnel.

Externally, the handgun bears a striking resemblance to the CZ series of handguns. Cocking serrations are both forward and to the rear with the sights mounted to the slide. Controls are biased to right-hand shooters with magazine release behind the trigger guard, slide release above and a 1911/CZ safety mounted at the top rear of the frame.

250x250 (1)

Its a decided fail to extended handgun size using a 6 inch barrel and coming in 45 ounces, nearly 3 lbs! Width is an inch (impressively thin), but over all length is 9 inches so it will have a long draw stroke for a combat pistol.

The 7.5 FK is a unique round.  BRNO Defense lists it at 2000 FPS and 880 ft/lbs of energy at the muzzle with the ability to roughly replicate the .44 Magnum in terms of route energy. Accuracy is touted as a 1.5 inches at 100 meters (an interesting mix of units, eh?). The round is rated to pierce Class IIIA ballistic protection (typical combat soft armor is IIIA) at 100 meters as well.

The sights are likewise unique. The front sight is lined up not just between, but inside the rear sight aperture to create the sight picture. Its a novel approach, as it will allow a shooter to see how far the blade is off when the pistol has a downward declination.


No word yet on final specs or availability/price. We’ll keep our eyes peeled for further details.

Specs per BRNO Defense:

Calliber 7,5 FK
Bullet weight 98-103 grains / 6,35 – 6,67 g
Magazine capacity 14 + 1
Barrel length 6 inch / 15 cm
Gun width 1 inch / 2,5 cm
Gun length 9 inch / 24 cm
Gun weight 45 oz / 1280 g

The above post is my opinion and does not reflect the views of any company or organization.


  • iloveczs

    Looks single action. Rebarrel that puppy into something straight walled I can easily reload for and sign me up.

    • DrewN

      DA/SA with some kind of moving mass recoil absorber under the barrel.

    • Paul Joly

      9x21mm with a sabot 5.56 bullet => same performances

      • Giolli Joker

        Which 9×21? Italian 9 or the Russian round?
        Anyway, here the bullet is in the 100grs range, a 5.56 would be in the 55grs range.

        • Paul Joly

          Yes, 9×21 IMI
          If a 5.56 at 2500fps isn’t enough you can increase the pressure or the diameter of the sabot.

      • Israel asskissing conservative

        Sabots can’t necessarily be used by private civilians, since they may easily be 1/4 the weight of a projectile, and the ATF may consider them to be “bullet jackets,” and therefore “armor piercing nuclear ebola darts.”

        Obviously, this assumes American.

        • Paul Joly

          Like simunition for instance?

    • gunsandrockets

      Video describes it as SA.

    • If it’s anything like other 10mm handguns such as the Glock 21 or EAA witness, you could potentially swap out barrels and recoil springs to shoot 10mm, .40, .357 sig, 9×25 Dillon. With some extractor tuning possibly 9×23 Winchester and .38 super as well.

  • Giolli Joker

    Actually it was introduced at IWA 2015…

  • Edeco

    O.O I want that. What’s the guide rod (?) doing that far from the hose? Looks expensive.

    • gunsandrockets

      Not guide rod. According to video it is some kind of recoil dampening mechanism.

  • Looks like a CZ-75 and a Steyr Hahn pistol had a illegitimate off spring. I like the looks though, kind of neat, not sure I would ever buy one.

  • Hensley Beuron Garlington

    I like. I want. Looks like a 1911 version of Robocop’s gun. Robocop meets steampunk.

    • oldman

      Was just thinking the same thing.

    • ostiariusalpha

      All it needs is some Bakelite grips to look like some alternate reality gun, where the Soviet didn’t collapse.

      • Anonymoose

        And decided to make their own version of the SOCOM pistol, way late in the game, just like we did with the Five-seveN and the Russian PSM and OTs-23.

        • ostiariusalpha

          It is very much like some combination of the Mk 23 with a Russian’s idea of what a PDW round should look like.

    • noob

      also this would be the perfect pistol for a darker and grittier Dirty Harry reboot.

      I know what you’re thinking: “Did he fire 15 shots or only 14?” Well, to tell you the truth, in all this excitement, I’ve kinda lost track myself. But being this is a 7.5FK Brno, the most powerful handgun in the world, and would blow your head clean off, you’ve got to ask yourself one question…

      • DJ9r

        “…do you feel Metric? Well, do ya, punk?”

        • Fegelein


      • Anonymoose

        I dunno…the .44 Magnum has a lot more actual power by balancing speed and bullet mass. Really light and really fast give lots of energy, but I wouldn’t take this hunting (unless I was hunting up-armored villains). The .44 is perfect for Dirty Harry because it’s a flashy, ridiculous, hard-recoiling gun. This is about as by-the-book as you could possibly get in an MIL/LE sidearm without going full 9mm.

        • uisconfruzed


    • thedonn007

      Looks more like a CZ75 and crosman 1377 combination to me.

      • MR

        I like the way it looks, as is, but with those MIL/LE/.gov aspirations, I figured there’d be a tac rail for lights, etc.

        • HR Pufnstuf

          A light? At 150 meters?

          • Cymond

            A pistol? At 150 meters?

  • Mike

    Nice to see something different.

    • noob

      I’m loving the innovation in the sights if they are robust enough to not break and clean enough to use under stress without getting confused with all the lines in the rear sight.

      Are ghost ring sights on pistols okay to use in competition?

      will this pistol make major power factor and fit in the box for competition use?

      • Xeno Da Morph

        It makes 200pf so you would want to actually down load it. Or throw a comp and a dot on there and shoot open. That would be awesome.

    • Giolli Joker

      Last year nobody cared. 🙂

  • Joe Schmo

    A 360p video for a promo from an arms manufacturer in 2016… that’s weird.
    The video did not really show much. They just said, “The weight of a .45, the recoil of a .40, and the power of a .44 Magnum” as if that is enough for everyone to drop their current handguns and buy this niche piece.

    I like to see new and different things, but this isn’t enough for me to see the true practical application in civilian, hunting, police, or military use. And I kind of chuckled when they mentioned competition use. Very few people want a competition gun that has recoil similar to a .40 S&W. Some may, but most do not. And being such a niche gun, there is likely not going to be a whole lot of aftermarket support for it. I don’t see this gun catching on any time soon.

    • SpartacusKhan

      .40’s are used in comp all the time, minor and major loads. .40 recoil is nothing, really – sharp, but little push

  • Ceiling Cat

    The most interesting thing since the 10mm.

    • Mazryonh

      How do you figure that?

    • Israel asskissing conservative

      It’s not.

      They give almost no information about the cartridge AT ALL.

  • FrenchKiss

    Wondering if it is legal to hunt deer with that round.

    • Robert Preston

      It would depend on the state in question.

      So long as the bullet is all lead, or designed to expand, and centerfire(which it is) – you can hunt with that cartridge in PA. However it would have to be in a manually operated firearm(no semi-auto rifles/handguns allowed for hunting in PA, unless you are missing one or both hands).

  • Anomanom

    Mmmm, so sexy.

  • Dracon1201

    That is one long barrel to get that kind of performance.

  • Mario AK

    Boberg XR75, the only model I’m interested in.

  • Surfgun

    So it is basically takes the Tokarev type round from 1,600 to 2,000 FPS.

    • Edeco

      Yep, amazing, heavier projectiles too, apparently.

    • Well, it’s based off the 10mm Auto case, not the Borchardt/Mauser/Luger/Tokarev case.

      • Surfgun

        I figured it based of a 10mm case head, with a slightly longer case to accommodate the bottle neck and the stubby bullet to equal about the OAL of a 10mm cartridge.

        • Surfgun

          The case is actuall a 10mm Magnum case trimmed to a length of 26mm. The standard 10mm case is 25mm in length.

      • Southpaw89

        So it uses an existing parent cartridge, that could help it in the commercial market, if the round can be reloaded I would certainly be less reluctant to invest in one. Does it take standard .308 bullets the way the old 7.5×54 does?

    • gunsandrockets

      More comparable to .300 BLK.

  • Martin törefeldt

    They made a good show about what the bullet can do at 100m.
    Just one question.
    A handgun is normaly used at close quarter, so whqt will the bullet to at lets say 5 or 15 meters?
    Will it do the same thing as on 100m or will it just pass trough the target with out doing to much damage?

    • If anything it will penetrate less at 5 meters due to it traveling 500fps faster, which will cause it to expand/tumble more rapidly.

  • Mazryonh

    Introducing a new proprietary caliber is always risky. What’s the caliber in metric again? 7.5mm by how many millimeters in length? Handgun bullets of that caliber haven’t been in fashion since 7.62x25mm Tokarev went out of style.

    And is this handgun going to have an accessory rail?

  • Max Durocher

    If you watch the video you will notice the guy words his statement to make it sound as if the United States Department of Defense has “tasked” his company to test this pistol.

    Playing word games is not exactly the hallmark of an honest company that puts out a quality product.

    Calling it now, this gun is gonna be junk.

    • Ranger Rick

      By junk you mean a POS that malfunctions or just not a commercial success? I’m unaware of BRNO having a reputation for building POS’s.

      A firearm with fine ergonomics and packability vs. a Desert Eagle or S&W 29 could peak my interest.

  • Southpaw89

    I like it, but I have to wonder what niche they’re trying to fill here, would it be for downed aircrew? Seems like folks have tried to fill that role before with very limited success. Civilian side I can see it fitting into the hunting handgun category, or maybe some kind of competitive target shooting, either way it will be interesting to watch.

  • Bob

    Actually, I’m a little surprised companiess haven’t seriously been trying to interest the military in higher powered pistols, given the rise in body armor throughout the world. The Five Seven was a feeble attempt at it, and the TT-33 and variants were too early for such things, but now…

    • Well at this point it’s a mixture of “getting ready to fight the last war” combined with technical limitations. Current handgun selection is trending towards 9mm/.45 handguns using newly approved JHP ammunition for the MHS program. This is based on the assumption that adversaries in the future will be much like the ones we face today – unarmored militants and 3rd world armies.

      If climate change leads to widespread upheaval, mass migration, water wars, and other nastiness that requires “urban pacification missions” around the South, then this is likely the correct call.

      However if the next war is against any type of modern adversary, using level III or IV armor, then the 5.7, 7.5. 7.62×25 will all be as ineffective as 9mm against hard armor (although possibly effective against helmets.) To meet the challenges of that level of protection, it’s going to require saboted tungsten ammunition similar to 6.5CBJ.

      And once your there, it really doesn’t even make sense to use a handgun when micro-PDW’s like the B&T MP9 are only 12″ long and weigh 3lbs, given the forward grip, integral red dot, and folding stock that this slightly larger platform offers.

    • Mike

      Bring back the 7.62×25.
      I believe Norinco make a Sig 226 copy in this caliber

      • William Elliott

        hell, I’m working on a 1911 in that cartridge…doublestack…

    • Bill

      In addition to body armor, chest rigs need to be considered: look at ISIS propaganda and you’ll see the need to batter a way through a rack full of AK mags. Taking a headshot is easier said than done, and hits to the pelvis don’t always disable a bad guy’s trigger or finger or detonator digit.

      • Bob

        I have been wanting to test a couple different things on some old surplus AK mags I have, but the range I go to probably wouldn’t appreciate some idiot trying to scatter pieces of metal and 7.62×39 rounds all over the place. I’m just guessing here, but I figure a fully loaded AK mag would do a fair job stopping a pistol round, but anything in the rifle category, except maybe 5.56, will go through easily enough.

        • William Elliott

          I think “The Box o Truth” did that one already

    • Brian M

      Seriously, why not just reissue TT-33’s and CZ52’s? Those things are what they’ve been looking for for years; the 5-7 was pretty much the 7.62×25’s wimpy nephew. I’ve been saying for years that there is a need and a market for a round like 7.62×25, and here’s a new contender.

  • Will P.

    So kinda a modernized version of the 7.62 Tokarev? I like it! I’ve always wanted a Tokarev, bad little pistols.

    • MPWS

      You said it for me. It also adds little more punch to mentioned cartridge; it all makes sense, but hardly has any use for police force or for civilians.

      • Will P.

        Well they are calling it a “field” pistol and show them shooting an elk with it so I’m wondering if they are trying to market it similar to how the 10mm started. Initially the 10mm was a handgun hunting cartridge that they tried to get military and law enforcement to buy into. It looks like a cool pistol, something kinda fresh is refreshing. But I don’t see this making it in military and LE because it’s not tacticool enough, that and it’s kinda big for a duty weapon.

        • iksnilol

          I am not shooting moose with the equivalent of .44 magnum.

          • Will P.

            No one told you to. But I would have no problems using a 44 for whitetail or hogs.

          • iksnilol

            Sure, whitetail and hogs. But way too small for moose (AKA elk).

          • Phil Elliott

            The Animal that was shot only weighed 360 lb., that’s a small Elk.

          • iksnilol

            Where do you find these young and malnourished Elks?

            Wait, my fault. In Norwegian the word for moose is elg, what you call an “elk” is an Wapiti. At least if my dictionary isn’t wrong. I am thinking of the big deer animal. That weighs like at the very least around 275-375 kg.

      • William Elliott

        you’re kidding, right? With good expanding ammo [I’m tinkering with what Marty Ter Weeme called the 7.62 Moscow Match right now, a Tok round topped with a .30 cal XTP short enough to fit in standard 9mm mags] it should be flat shooting, low recoil and have plenty of oomph for penetration [and if you have a North Hollyweird shooting, switch to hardball instead of having to get your rifle…]

    • Sir Blinchik

      Get one. Zastava M57, only way to go! 🙂

  • BrandonAKsALot

    It’s so ugly I love it.

  • Salty Nuts

    Ballistics similar to .30 Carbine in a neat semi-auto hand-cannon, what’s not to like. Seems like a lot of potential for a mini-carbine too.

    • noob

      Carbine? Hey that just gave me an idea – what would a kriss vector optimized for 7.5FK BRNO in full auto be like as compared to an akm?

      Would the extra barrel length over the pistol get comparable velocity to a 10″ ak pattern rifle?

      Would having a full auto smg that shares ammo with your pistol be useful now that they are chambered in a powerful armor defeating pdw cartridge?

      And what would a 30rd magazine of lehigh defense controlled chaos projectile in 7.5FK look like ripping up a gel block in full auto?

      • iksnilol

        Could be somewhat feasible, I mean, it is only about 80-100 m/s slower than the 7.62×39 from a 25 cm barrel.

      • Daniel Q

        Honestly, this caliber looks like 7.62×25’s ripped stepson, and from what we know about 30Tok, if that one was a mean little round, this one ought to be a champion. As for your imagery, I bet an SMG with a 10-12″ barrel using this could compete in the close protection and even urban warfare categories with rounds like 7.62×39 and 5.56×45. Now we wait for Nat F to show up and lecture us all about how this new round and all new rounds aren’t worth it, because 5.56×45 is t3h besst0rz

      • Israel asskissing conservative

        Kriss Vector has a shorter barrel than this handgun.

  • gunsandrockets

    Oooh! A semi-auto hand-cannon. I like.

  • Xeno Da Morph

    I shoot and hand load the 9×25 Dillon a lot. This 7.5 FK is really a neat development for a small ish caliber high velocity handgun cartridge with a streamlined bullet. Interested to see where this goes.

    • I was also thinking that the specs are nearly identical to 9×25, but with a narrower bullet better suited to high velocity. Hopefully we will see conversion barrels down the road for 10mm firearms to shoot the 7.5.

      In the meantime, how do you like shooting 9×25, and how is the reloading process? I’ve been looking into it as an option for a red dot build G20 Longslide.

      • Paul W.

        OOOHHHH……30 carbine specs with different bullet.
        Can we all say: Ruger Single Action .30 Carbine!

  • Indeed it is!

  • Goody

    That pistol is ugly and huge, but the round is interesting.

    Another video shows them attaining the 1.5″ groups with a laboratory rail gun type set up, bolt action, with a 6″ test barrel. Just because the barrel length is the same doesn’t prove the pistol…

  • DW

    >10mm parent case
    >CZ75 format
    Get ready bois HYPE INCOMING

    • JK

      Bren ten remake?

      • DW

        Except not complete vaporware, and less recoil.

  • Darren Hruska

    Now, THIS is kind of what I’d expect out of a “combat pistol.” Like, not a carry pistol, but one you’d take to war or defend your home with or wherever you don’t quite need something overly compact and concealable. Most of the other ones I’d consider “worthy” are either select fire prototypes and/or probably aren’t going to be shipped over here due to import laws (not readily available to civilian market). Basically, a pseudo-PDW that’s a bit more compact than the typical PDW.

    • Fegelein

      It’s pretty much a TT-33 with a few tweaks. 🙂

  • Giolli Joker

    To me it looks like the bastard child of CZ52 and CZ75.
    I like the forged look of the frame.
    Overall, a very attractive toy.

  • Heebrew Hammer

    That’s 357 AMP Automag accurate…..nice….

  • mechamaster

    wow, the .44 Desert Eagle killer with nearly twice the capacity… ( for game / film enthusiast )
    “Nah, just for fun..^^ ”

    But, I think it’s better to paired it with some pistol-to carbine adapter. ( Even it add some cost and extra tax )

    • Paul White

      what the hell happened to that glock?

      • mechamaster

        It mutated into blaster handgun…. ^^ ( just kidding )

        The Glock is inside the carbine adapter.

  • AD

    25mm at 100 meters? That’s pretty much 1 MOA isn’t it? If that accuracy is for real, then I’m VERY impressed.

    • Doom

      25.4 mm is one inch. this HANDGUN is MOA at 100 meters… Many rifles cant even claim that.

  • guest

    lol archaic gun design with new wildcat cartridge

    sure, it will sell well 🙂

    • Paladin

      Compared to the 1911 the CZ75 is hot off the design table, and yet 1911s sell like hotcakes. I myself am quite fond of my CZ85, accurate, nice trigger, and very ergonomic.

  • santi

    Cheese ball video but I love the gun. I’LL TAKE ONE. But first let me take a chip off the 401k cause this will not be a median priced pistol.

  • thebackwoods

    I have recently installed the 460 Rowland in one of my 1911 45acp pistols, I have not tried it at long distances yet but power wise it looks to be in the same ballpark as the 7.5 or 44 magnum power range. The advantage with the 460 is being able to reload for it as the 460 Rowland brass is readily available and being a straight walled case and common bullet size means projectiles are easily obtained as well. Also if you want to swap back to the 45acp, all you have to do is change out the components and you have the 45acp pistol in it`s original form. That is versatility.

    • Marc

      Having a 10 mm case head this pistol is a barrel swap away from 10 mm, .40 S&W, .357 SIG and possibly even 9 mm (if the bolt face/extractor dimensions allow).

      • thebackwoods

        The 40 cal, 10mm, 357Sig all have the same size case at the primer end, just the primers are different sizes in 357 Sig, 40 and 10mm the 357 Sig and 40S&W take small primers and 10mm take large primers. Although it should not be a major problem if the firing pin is centered correctly.

  • Jarhead0369

    It’s a gun and caliber in search of a purpose. Too big, too heavy, and another oddball in anyone’s supply chain.

  • Madcap_Magician

    Strangely attractive and a cool concept, but it goes on the list of guns that I would buy should I become independently wealthy one day, which is already quite long.

  • Evan

    Sounds like a cool caliber and I definitely like the sights, but that thing is butt ugly.

  • Sickshooter0

    “The autopsy was…delicious”

  • TheNotoriousIUD

    I want that.

  • Nice catch!

    It appears that they also sleeved the primer pocket so they can use Small Rifle primers.

    In some ways it is a throwback to Paul Leitner-Wise’s ill-fated PDW round, the 7.82x24mm. It looks like he intended it as an alternative to the .224 BOZ, designed by Bill Alexander.

    Here is the patent application for the 7.82x24mm:


  • Bill

    The sights are way complex. I’m not real bright, but if I cannot see my front sight it doesn’t take too long to figure out that it’s low.

    For executive protection or those working in the wide open spaces this could be really cool.

  • tenmillimeter

    you lost me at proprietary caliber

    • maodeedee

      A 10mm magnum necked down to 30 caliber producing 2000 fps out of a six inch barrel with a 100 grain bullet is nothing to sneeze at. Those are 30 carbine rifle ballistics out of a pistol.

      10mm magnum Brass is available from Starline, the 10mm magnum case is 1.242 – 1.248 O.A.L while a standard 10mm auto case is only .990 OAL and the 40 S&W is .850
      I like this gun a lot. As far as the sights, I’d actually have to try the gun out before I made a judgment call, but sights are easy enough to change on any handgun and I notice the rear sight is dovetailed,

      • Mazryonh

        I thought that tales about .30 Carbine’s lack of stopping power were relatively common in WWII. It would be interesting to do some gel testing with both .30 carbine and this new caliber.

        • Lysenko

          Lack of stopping power relative to the standards set by rifles of the time. That is, .30-06. It’s a very wimpy RIFLE round. comparing it to -pistol- rounds is something entirely different.

          That said, I wonder about the terminal ballistics at ranges under 100 meters. I notice that that is not discussed in the video. Sure, muzzle energy is super high, but how much of that is actually delivered to the target?

          Is it actually tumbling/fragmenting the way a high-velocity, low diameter round needs to in order to deliver serious damage, or at 5-25 meters are we going to get the same sort of inconsistent terminal performance and overpenetration that led the US military to spend lots of time and money reworking our 5.56 ammo?

  • TJbrena

    I love everything about it but the sights.

  • Squirreltakular

    Very, very cool. Could most of that extra heft be from the recoil reduction system?

  • gunsandrockets

    Even if the pistol never makes it, I hope that cartridge does.

  • Dolphy

    Somebody finally decided to quit messing around and recreate 7.62×25.

  • valorius

    The latest variation of the FN57 concept.

  • Citizen

    Only 90 years late to market.

  • William Elliott

    if the OAL is what I think it is, thats based off the 97 platform [45 ACP, 10mm Auto, .38 super] and not the ’75. Be fun to find out…I’d like to see it in here in the US. Both in the native pistol and as a glock conversion. Might be a .22 TCM killer.

  • Jason

    So couldn’t I just buy a Glock 40 and run Doubletap 135 grain bullets? I won’t have 880 ft lbs, but maybe only 100 less.

  • Lou

    The uninformed think this round does not equal the power of the 44 mag, but the 44 mag loses velocity in the air like pulling a sailboat. This round is small diameter and long so it does not lose velocity as fast.
    They also seem to forget that this round is larger in diameter than a 7mm Rem Mag, no one would doubt it’s ability to take down a large brown bear.
    I would sure like to have one of these pistols. I have a 44 mag revolver and will keep it. But a 44 mag will not penetrate body armor at point blank range, this pistol will do the job at 100 yards.

  • Jason

    Doesn’t my arm do what their recoil damping device does?
