TFB REVIEW: KRISS Vector in 10mm!

It’s hard to believe that more than a decade has past since the development and release of the original KRISS Vector. By now, if you haven’t shot a KRISS, know someone who owns one or at least handled one in a gun store, it’s safe to say you’ve been seriously lost: we are talking Tom-Hanks-desert-island kind of lost. Love or hate the design and ergonomics, this is what firearms innovation looks like. And now, after all these years, KRISS has finally released the Vector in the the sledge hammer-force caliber of 10mm.


“What’s that? Yes you can suppress 10mm , Wilson!”

Here’s the deal: if you are looking for earth-shattering reveals in this review, be prepared to be disappointed. Aside from the caliber change, this is the same Vector that has been shot and reviewed hundreds of times over on the internet and in print. In fact if you just plain hate to read, I’ll summarize the review in a few short words: reliable, good and bad ergonomics, 10mm, heavy, fun, bore height, 10mm, quality and 10mm.

Still here? Good. Let’s lay it all out.




Probably the most controversial aspect of the Vector is the articulating mechanism and delayed blowback operation that works to reduce felt recoil and prevent muzzle climb. At the end of the action’s travel, the inertia block and bolt are forced down into a recess behind the magazine well. The theory is that the lines of force are directed downward rather than back toward the shooter as perceived in-line recoil.



It’s an interesting concept that has been debated for years and I will say that the select-fire versions of the Vector are extremely flat shooting, especially for their dizzying rates of fire. The semi automatic 10mm version also had little to no muzzle rise. But without some scientific equipment (or modeling) I am unable to discern if the inertia system, the gun’s weight or a combination of the two should be given the credit.

This version, the SDP, is the pistol variant of the Vector. Carbine and Short Barreled Rifle (SBR) models are also available. At the end of the review I’ll offer my two cents about which one I’d grab given the choice.




Included below is the official 2016 specification sheet for the Vector Second Generation SDP. My one highlight here is the weight: this “pistol” clocks in at nearly six pounds – unloaded. Forget extended one-handed point shooting, the Vector is a beast.


I’ll pose this next question like the beginning of a bad joke: “How do you shoot an almost seven pound pistol chambered in 10mm?” Answer: Carefully. But seriously, the other important specification that makes the Vector SDP manageable is a single-point sling attachment on the pistol cap. More on that later.




Last note on the weights and measures. The Vector’s barrel is threaded in a standard right-hand 9/16 x 24 pitch. Most .40S&W and .45 caliber suppressors can handle 10mm.* So repeat after me: “I will be suppressing my new KRISS with a dedicated silencer.”

* Check with your manufacturer before jerking that smoke wagon.




I really like the overall handling of the Vector – it seems to fit my shooting style. Bring everything in close to the body tight and compact. The support hand seems to fit perfectly on the integrated vertical foregrip VFG magazine well. (Remember form our AOW discussion a few weeks back, a pistol with a VFG falls within the boundaries of the National Firearms Act (NFA). But since the support hand grip area is purpose-built as a magazine well, feel free to use it as you wish.



In my opinion, the pistol cap single point sling attachment is really what makes the Vector SDP useable as a “pistol”. Once attached, pushing forward with your strong hand creates a sturdy shooting platform that almost mimics having a stock. Almost. But it definitely helps manage the KRISS’s hefty weight.



If you didn’t already know, all of the Vector variants utilize Glock magazines, which is great for many reasons. For one, all of Glock’s products are built to work – including the magazines. Second, if you own a G20 (10mm Glock) you now have two guns that share the same ammunition feeding device. Always a bonus.



For now you are limited to the stock 15-round capacity since the magazine extension available for the .45ACP version will not work with the 10mm magazines without “serious modifications”. Suck it up: if 15 rounds of 10mm and a few magazine changes won’t get the job done, that T-Rex just isn’t going to go down.



The build quality of the Vector really is confidence inspiring. If you have ever had the displeasure of holding a shoddy-feeling polymer gun, fear not. The KRISS is the opposite of cheap.




I’ll get my gripes out of the way first:

With normal strong-hand positioning, the safety selector seems to dig into my knuckle when switched into the ‘fire’ position. After shooting a few hundred rounds, the feeling wasn’t pleasurable. I’m willing to admit that my personal shooting style or hand positioning could be to blame. But no matter how many grip positions I tried, I couldn’t get it to work for me.





On the other hand (literally) my support grip seemed to interfere with the bolt hold open lever. Every three or four rounds, the bolt would stay locked to the rear. And adjusting my grip didn’t seem to help – my palm seemed to always find its way back to the lever, perpetually riding the hold-open setting.

Again, this could simply be my personal hand placement or grip style, meaning other shooters might not ever notice the issue.



Let’s face it, the Vector is a close quarters gun. And it’s built for that duty in every way but one: the height of the sights above the bore line. With the included Magpul flip-up sights, the point of impact feels miles below the shooters point of aim. For CQB-style shooting, I like to envision the worst case scenarios – like taking a well placed headshot at seven yards.

Using the Vector for hostage-type shots is a challenge. My offset was so high that the intended target was completely obscured. I didn’t bother trying to adjust the site elevation either – even if there was enough movement, which there isn’t, zeroing at ten yards would leave all other range distance estimations skewed to the nearly unusable.

Now for the good news: everything on the 10mm Vector ran flawlessly. As big and weighty as it is, the KRISS is fun to shoot, accurate and I didn’t experience a mechanical stoppage of any kind. Recoil was light and sweet. Ejection of spent cases was at a textbook three o’clock position. Working the action was tight and repeatable and the trigger had a satisfying and useable pull and reset.

Again, the KRISS is one of those guns that gives you confidence just to hold it, but being chambered in 10mm is just icing on the cake.




Ok, so, would I buy this gun for myself? Probably not. Here’s why:

  1. I don’t reload or stock 10mm ammunition.
  2. The hand and control placement options don’t work for me.
  3. The bore line is too far below the sight picture for close shots.

Would I dissuade anyone else from buying the KRISS Vector in 10mm? No. Here’s why:

  1. If you own a 10mm Glock pistol, the Vector is a great complement with native magazine interchangeability.
  2. The ergonomics may be a perfect fit for you.
  3. It is a smooth shooting package that is fun, reliable and accurate.

Hand positions aside, I could easily see myself getting behind a suppressed Vector SBR in 9mm. I’m guessing that setup would be super-fun.

My one regret with this review is that I wish I had some real “full powered” 10mm loads to run through the Vector to rate its felt recoil-reducing operation. Next time.


From the KRISS USA Website:

The KRISS Vector GEN II is the next evolution of the Vector platform, taking it from a firearm into a multi-caliber weapon system and is compatible with the ubiquitous Glock magazine. Changing between calibers can be done in seconds, without any tools. The KRISS Vector GEN II is more ergonomic with a redesigned trigger, a short throw ambidextrous safety lever, and a more comfortable pistol grip.

The KRISS Vector SDP is the Non-NFA semi-automatic pistol variant of the KRISS Vector platform. It features a short, threaded, 5.5” barrel. A rear quick detach sling point assists with carrying the firearm. Additional standard equipment on the KRISS Vector SDP are the Magpul MBUS sights, full length picatinny top rail and a Glock Magazine. Although this SDP maybe small, it still has the same capabilities as its larger counterparts and is civilian legal in most states.

The SDP is available with either a 5.5”” threaded or non-threaded barrel.

A very special thank you to ARMSCOR USA for providing plenty of 10mm ammunition to test the new Vector. The next time you are shopping for rounds, please consider ARMSCOR’s line of quality and affordable ammo.

  • Disarmed in CA

    Needs a 15″ longer barrel, a fixed stock and 10-round fixed mag and Cali here we come!

    • Pete – TFB Writer

      Loading that fixed mag doesn’t give me a warm and fuzzy.

      • Noigiallach

        All about the featureless.

      • Stan Darsh

        On the opposite side of the magazine size spectrum, I’ve actually had surprisingly good luck with a few of the KCI 27 round .45acp mags in my 10MM G20 after reshaping the feed lips.

        • Pete – TFB Writer

          Good to know. Thanks.

    • Noigiallach

      The 10mm Carbine is already in CA. Saw one at Turners.

  • nova3930

    Gah, now I’m gonna have to get one and a G40 to go with it…

    • Pete – TFB Writer

      I like that idea. KRISS should partner up with Glock to offer package deals.

      • nova3930

        I’d go for it. I’ve already got a couple of 10mm but a 10mm pistol/sbr and a long slide with an optic and mag compatibility would fit right in….

        • JSmath

          That seems like the opposite of what’d be useful, to me.

          If you are going to go full doodads and optics with the KRISS, then I would think you’d want a standard or compact frame so you can/would actually carry the Glock as a backup.

      • CS

        Not likely to happen since KRISS is also an importer of Sphynx pistols.

        • CS

          Maybe a dealer will do a package deal, but I doubt you’ll see such an offer from the MFGR.

        • iksnilol

          Oh the humanity, KRISS imports actually good pistols?

          • Pete – TFB Writer

            Take two weeks off from being anti-Glock. Good for the soul.

          • iksnilol

            If I wanted salvation for my soul I’da reconciled with my family and went to a place of worship.

            I don’t intend on doing either of those.

        • Pete – TFB Writer

          Excellent point.

  • Porty1119

    Lost? I’ve never even talked to anyone outside of the internet who’s heard of the thing, let alone seen one in the wild. If I were in the market for a heavy, overpriced subgun, I’d be buying a Thompson. At least Thompsons have class.

    • .45

      Ditto. My sole experience with it has been in Far Cry video games. Don’t recall ever seeing one in a gun shop, and certainly never fired one.

      • Richard

        I’ve seen a few in gun shows in Florida before. The dealers don’t like to stock very many of them.

        • .45

          Only ever went into one gun shop in Florida, but I have been in pretty much every gun shop for fifty miles around where I live in my home state. In said gun shops I have handled everything from WW2 Arisakas all the way up to the civie version of the Styer AUG, but still never seen a Kriss, not even next to the Desert Eagles and other movie guns. Just not a thing where I am.

    • Stephen Paraski

      Open Bolt?

  • Paul White

    only 1250 more dollars to go…unless I get distracted by something first. Damn I want it though

    • User

      Recoil midigation basicly is only usefull for fullauto. The cartridge is low pressure and basicly low performance. And sucks at penetration. A P90 is shorter, the PS90 propably similar lenght than a Kriss without some ATF stamp (i dont know how that works), and if you use a more heavy bolt carrier, you can load some really hot stuff that outperforms .45
      Expecally the extrem lenght and just stupidly short barrel on the kriss is ……
      The P90/PS90 have a way, way, longer barrel in the same package and 50 rounds!

      If you think about it, it really isnt that great.

      • Nick

        Yes the 5.7 will defeat body armor but it is essentially a glorified centerfire .22 mag. If you don’t need the capability to defeat soft armor like most civilians a 9mm would be a better choice as would 10mm. With some of the hotter loadings a 10mm out of a 16″ barrel has the same or better M.E. than a lot of/most .223 loads. For the role that these were designed for I’d take a 10mm Vector carbine/sbr over a PS90.

  • c4v3man

    A firearm doesn’t have to have a point to exist. It can merely be cool, novel, or just be available for sale to have a spot on the market.

    That being said, the Vector seems focused solely on the recoil reduction feature, which seems lost on semi-auto fire. The guns an anti-bullpup, putting the action way out in front of where you’d expect it to be to where it seems really space inefficient. I just don’t see the point. That being said, the 10mm cartridge might actually make some sense in the non-sbr 16″ format… ballistics by the inch shows light-to-medium weight projectiles gaining about 200fps or roughly 15% increase in speed/30% increase in ft-lbs of energy if that’s your thing.

    Novel design though, wish we could buy the full-fat version instead of just diet-vector. If only we could get the NFA or GCA ’86 repealed…

    • Joe

      If the recoil redirection is as significant as claimed, why not apply the concept to 7.62×51? Make it a bullpup too; with the space saved at the rear you might achieve a reasonable LOP.

      • User

        People tryd it. And you dont really save space actually. And there are WAY better ways to reduce overall lenght, and recoil.

        Also 7.62×51 doesnt make a lot of sence. Too heavy, un aerodynamic, etc.
        6.5 Grendel outperforms it at 1000meter. And 6.5 Creedmore even more so. And there still way better cartridges possible.

        • Nick

          I don’t really know if 1000m performance is a good enough reason to choose the caliber for this hypothetical bullpup. I do agree that there would be a better option than 7.62×51 but 1000m performance wouldn’t be part of my criteria.

    • Ryfyle

      Well Trump did get elected. time to get back to pushing those issues.

  • Der Fuhrer

    What’s the point? $1400 for a 10mm pseudo-pistol?

    • Duray

      Pretty sure the point is shooting stuff.

  • Joshua

    I have a 9mm with a brace. I love it. ETS and Pmags work great. I’m getting the brace converted into a side folder using factory Kriss USA parts. As a faux sbr, it works great

    • Stan Darsh

      Hopefully you’ll send in a photo when the side folder is ready to TFB for a pic of the day article.
      P.S. How do you like the ETS Group mags?

      • Joshua

        I shall when I have it back. The ETS 31 round magazines work great. No issues feeding so far. I have about 10 of them and I think I need to invest in some more and give the 17 round mags a try. I will be getting some of the 27 round pmags when they become available.

  • TexianPatriot

    I have said it before and will repeat it now. The KRISS is an excellent design for full auto recoil mitigation, but for civilians it make absolutely no sense to have unless you are a little short in the pants and need to impress someone. It has a pistol length barrel, fires a pistol cartridge, is longer taller and heavier than a pistol (in pistol form) it is longer taller and heavier than almost all other pistol caliber carbines, it also cost 2 to 3 times the price of said pistol. I see no plus for the civilian side.

    To add to this. KRISS developed a intuitive, compact action that fits in a very small area, then they ruined it by putting it in a standard format instead of bullpup. This action, in a bullpup, in a rifle caliber, could be a great weapon.

    • Bullphrog855

      You’re right that it’s not practical, but the KRISS is cool so it doesn’t mater.

    • JSmath

      I find it ever slightly ironic to your sentiments that you’re a Texan. A suppressed 10mm KRISS SBR seems like an ideal hog dispatching tool. 10mm isn’t super easy to handle in pistol form, and the extra weight is a boon in that regard. Having one paired with a Glock backup just-in-case seems like one of the best ways to roll into the field, particularly if one were a fan of 10mm.

      It’s f-ing expensive, for sure. But after having a ton of fun and eventually breaking my sub2000, I feel like I’d rather upspend if I gave the PCC thing another go.

      • somedingus

        “10mm isn’t super easy to handle in pistol form”
        As an avid G20 shooter I would dispute that statement.

        • Blaine

          What would you say the recoil is like? I’ve never shot 10mm.

          • Richard

            Think like .45acp but faster.

          • Nick

            It’s definitely a little “sharper” with true 10mm loads, .45 is more of a gentle shove where 10mm is a little more violent. Still far from hard to handle, I was pretty impressed with how fast I could get back on target with my G20 and a dueling tree using moderately hot ammo. Definitely still faster with my G17 but far from slow and inaccurate with the G20.

        • RSG

          Avid being the key word there.

      • iksnilol

        I dunno, for dispatching hogs I’d recommend a PKM to be honest.

        • Marc

          200+ gr 10 mm has plenty penetration for glorified pigs.
          Ted Nugent killed a Cape Buffalo with his Glock 20.

          • iksnilol

            Yeah, and my neighbour knows someone who killed moose with a .22.

            Still going with the PKM for hogs.

      • TexianPatriot

        I have a purpose built, short barrel, 300 blackout for pigs. And it was built for a fraction of the price. No irony needed.

        And I really think the notion of your main weapon and back-up/sidearm sharing ammo and mags is stupid. I didn’t at first but after a little thought it becomes clear.
        When are you most likely to use a back-up? Sure, a failure would cause the need, but most people that have firearms take care of them, and if you are using something prone to failure, you probably are too dumb to carry a reliable back up anyway.
        No, you are most likely to use your back-up when the ammo for your main goes dry. But if your back-up shares ammo and mags, your out of luck.

      • Mazryonh

        JSmath, if you’re in the market for a PCC in 10mm without breaking the bank you might find getting a Mechtech Carbine Conversion Unit which attaches to a lower of a Glock 20 and can use the same magazines, so you could use a Glock 29 for backup. You would need to thread or shorten the CCU’s barrel through another gunsmith though.

  • iksnilol

    I don’t see why a .40 S&W suppressor shouldn’t work on 10mm Auto. I mean, most 10mm ammo is just lower pressure .40 S&W (factory ammo that is).

    • Blaine

      I believe a .40 can does in fact work. In Nutnfancy’s Glock 20 video, he shows this. (Idk why I watched it)

      • Jared A. Faber

        You had a few days to kill?

    • Blaine

      That being said, do any suppressor brands actually make .40 cans anymore? I thought 9mm and .45 were the only ones being made.

      • SP mclaughlin

        I think there are .40 Silencerco Ospreys.

  • mig1nc

    Bore height doesn’t matter with 10mm. A near miss will still knock your leg off.

  • Richard

    If I had the money on hand for it, I would think about the alpine color one and sbr it.

  • noob

    I guess they’re not writing “grip zone” on the magwell any time soon

  • Mazryonh

    If Kriss wanted to promote this, they should have a side-by-side comparison showing how much easier their KRISS SMG in 10mm is to control compared to the older MP5/10 in the same caliber. That’d be something to see.

  • janklow

    “By now, if you haven’t shot a KRISS, know someone who owns one or at
    least handled one in a gun store, it’s safe to say you’ve been seriously
    lost: we are talking Tom-Hanks-desert-island kind of lost.”

    so i go to gun shops, go to gun shows, have dozens of guns and shoot them regularly… but because i haven’t had enough random KRISS time, i’m lost? huh.
