This is a review I've been really looking forward to. The Kriss Vector is iconic for me because it was one of the first "space" like movie guns I remember from my teenage years.
What is the Kriss Vector?
The Kriss Vector is a gun that looks different from most others. It is known for having less “kick” or recoil when you shoot it, which makes it easier to aim and control.
This is because of its special design that helps reduce the force that pushes back on the shooter.
The gun is used by some police forces and military, but it is also popular with people who like to collect and shoot guns for fun.
It can shoot quickly and comes in different calibers and models to fit different needs.
Overall, the Kriss Vector is famous for its unique look and how easy it is to handle when firing.
Vector SDP vs SDP Enhanced: Which Model?
Kriss offers the Vector in several configurations, and the naming can be confusing. The two main pistol variants are the SDP and the SDP Enhanced, and understanding the difference helps you choose the right one.
The standard SDP is the base model. It comes with a shorter handguard that doesn't extend past the barrel, Picatinny rails on top, and the core Vector features. It's a solid gun, but the handguard limits your accessory mounting options.
The SDP Enhanced adds a longer M-Lok handguard that extends further forward, giving you more real estate for lights, lasers, and vertical grips. It also includes QD sling mounts and a slightly different aesthetic that many prefer. For most buyers, the Enhanced is worth the modest price premium because the accessory options are significantly better.
I went with the Enhanced specifically for the handguard. If you plan to run a suppressor, the longer handguard gives you room to mount a light forward of where your hand naturally grips the gun, which matters for practical use.
Gen 2 vs Gen 3 Vectors
At the time of writing, Gen 2 Vectors are what you'll find on dealer shelves. The Gen 3 has been teased by Kriss but doesn't have a firm release date yet.
The biggest confirmed improvement in Gen 3 is an ambidextrous magazine release. The Gen 2's mag release is right-side only, which is a notable limitation for left-handed shooters. Gen 3 also promises refinements to the trigger and controls, though specifics remain scarce.
Should you wait for Gen 3? Probably not unless ambidextrous controls are essential to you. The Gen 2 is a proven platform, and waiting for a "next gen" product with no release date means missing out on range time now. If you're left-handed, consider how much the right-side-only mag release actually impacts your shooting before making it a dealbreaker.
Why a PCC?
A pistol caliber carbine (PCC) is a type of firearm that shoots pistol-caliber rounds instead of rifle rounds but is typically in a rifle size configuration instead of a handgun.
Here are two key reasons why a PCC can be a great choice:
Increased Accuracy: A PCC is easier to shoot accurately than a regular pistol.
This is because you can hold it with both hands and brace it against your shoulder, which helps you keep the gun steady.
The longer barrel gives the bullet more time to stabilize, making it more accurate.
Small and Easy to Handle: PCCs are smaller and lighter than most traditional rifles.
Their compact size makes them easy to carry and maneuver in tight spaces, such as around corners or in small rooms.
This makes them a good option for home defense or shooting in places with limited space.
Best Caliber for the Kriss Vector
The Vector comes in 9mm, 10mm, 45 ACP, and .22 LR. Each has its place, and the "best" caliber depends entirely on what you want from the gun.
45 ACP is the original Vector caliber and the one that showcases the Super V recoil system best. The heavier, slower round benefits most from the downward bolt travel, resulting in noticeably less muzzle rise than you'd expect from a 45. If you plan to suppress, 45 ACP is naturally subsonic in most loadings, so you don't need to hunt for specialty ammo. The tradeoff is magazine capacity—you're limited to 13+1 with the extended Glock 21 magazines.
9mm is the practical choice for most shooters. Ammo is cheaper and more available, magazine capacity jumps to 33+1 with Glock 17 magazines, and the recoil is already mild enough that the Super V system almost feels like overkill. If this is a range toy or training gun, 9mm makes financial sense. The downside is that 9mm is supersonic, so suppressed shooting is louder unless you buy subsonic loads.
10mm splits the difference in some ways. It's more powerful than 9mm with better terminal ballistics, but magazines are harder to find and ammo costs more. The Super V system does good work taming 10mm recoil. This is the caliber for someone who wants genuine stopping power in a PCC platform.
.22 LR exists for training and plinking. It's fun and cheap to shoot, but it's not a serious defensive option.
I chose 45 ACP because I wanted the gun for suppressed shooting, and the look of a Vector with an Osprey suppressor was too good to pass up. If I were buying purely for practicality, I'd probably go 9mm for the capacity and ammo savings.
Ergonomics & Firearm Overview
The Vectors' most significant selling point is that the gun has extremely controllable recoil and excellent ergonomics.

The first Vector I shot was in high school; a friend's dad had purchased a 16" barrel model, which was a lot of fun to shoot.
I knew early on that I had to get my paws on a Vector one day, and about a year ago, I finally picked up a Kriss Vector.
The Kriss Vector I'm reviewing is the Kriss Vector SDP Enhanced Gen II in Multicam Black chambered in 45 ACP.
Why did I choose this model?
Simple. I knew I wanted to put the classic Silencer Co Osprey suppressor on the gun.
I wanted that look, and if I'm going to suppress the gun, why not buy a gun that's ammo is already subsonic?
So that's why I landed on the 45 ACP.
The Multicam Black spoke to me because it matches so well with several range bags that we make here at Lynx Defense.
Picking the Enhanced model option came down to the enhanced attachment features, which I liked the best.
Safety
Safeties can be tricky on unique firearms like the Vector.

For example, I hate the stock AP5/MP5 safety selector because it sits so high in the safe position, making it hard to actuate.
The Kriss Vector safety is as good as it can be.
The safety is at the top of the grip frame, so your thumb naturally falls on it when you grip the gun.
It has a short but stiff throw and is ambidextrous.
Pistol Grip
With the Vector, the grip ergonomics are a weird blend of pistol and AR-15.

It has a very comfortable grip and decent texturing, but nothing extreme.
An aggressive grip texture is unnecessary for this gun because even in 10mm, it's a very low-recoiling gun.
The pistol grip connects to the magazine well which doesn't impact the ergonomics but brings us to our next section.
Magazine Well
The magazines for all Vectors are Glock pattern magazines.
So the Magpul magazines and anything Glock based will work with the Vector.
I like to stock up on magazines and so I got a bunch of Glock 21 magazines and added the Kriss Vector Magazine Extensions.
But buying ready-to-go magazines for the Vector is an option as well.
The one downside to the Gen II Vectors is the lack of a magazine well flair of any kind.
While it's not a big deal, don't expect any help funneling your magazine into the well.
Magazine Release
The magazine release is located on the vertical portion of the gun, where most people's hands will likely fall on the Vector platform.

That makes it easy to drop magazines when the time comes for a reload.
Unfortunately, the magazine releases are not ambidextrous on the Gen II models.
However, the Gen 3 Vectors will have ambi magazine releases (release date unknown).
Bolt Release/Hold open
With a unique design, look, and feel you can only imagine some of the controls are going to be different.

The Bolt Release/Hold open is one of those unique controls.
It sits just about the magazine well, almost directly in the middle of the gun.
It works on a pivoting system and is large enough and easy to use.
While shooting the other day I had my hand over the bolt hold open and shot the last round.
The hold open, slapped my hand, and startled me, but it didn't hurt my hand.
I realized I was holding the gun and had my hand over the hold open, and it was doing its job and going to last round bolt hold open.
This is something you don't have to worry about on AR-15-style guns because those controls are nowhere near where you grip the rifle.
It was nothing bad and not a criticism, just something that happened that was worth noting.
Charging Handle Configuration
The Gen II charging handle lays flat along the left side of the gun.
For the most part, it just sits there and minds its own business until needed.
It's pretty easy to grab but not as easy as a fixed charging handle that sticks out.
On my 45 ACP model, the charging is extremely stiff, but the stroke is extremely short, so you don't have to pull it back very far.
Stock and Brace Option
I purchased the Vector as a pistol without a brace with the intent to Form 1 it and make it an SBR (which I did).

I added the Kriss Vector stock (again, in terms of aesthetics, I was going for the classic version of the Vector) and the Kriss Verticle foregrip.
I can't speak to shooting this gun in the pistol configuration because I didn't touch it until Form 1 came back and all of the accessories I wanted were put on it.
Factory SBRs are hard to come by, but they do exist.
So if that's your thing, you can find one. Just be patient or buy a pistol and Form 1 it.
Muzzle Device
There is no "muzzle device" for the vectors.
You either get a long barrel version with a shroud or a short barrel version with a thread protector.

If you are considering a Vector, I highly recommend you buy one to suppress if it's allowed in your state.
Ammo for Kriss Vector
I shoot 230 GR AAC 45 ACP amount out of the gun almost exclusively since I bought it.
Blocksy: Content Block Filter
I have had no issues with 230 GR ammo but haven't tried anything outside that grain weight.
Shooting the Kriss Vector
I love shooting the Kriss Vector.
It's one of my favorite range guns to take out and stretch out.
Rapid fire is smooth and staying on target is extremely easy.
If you are looking for a smooth-shooting gun that is fun to take to the range, I'd highly recommend the Vector.
However, I will say all of my shooting has been done suppressed and I haven't shot an unsuppressed Kriss Vector in 15+ years.

Here is my target sight at 25(ish) yards. As you can see, the Vortex UH-1 that I was using was low out of the box but dead center.
I never touched the windage; I only had to adjust the elevation.
Not my best sight in work but I could see the walk up so I didn't group multiple rounds on #2 and #3.
Once I knew I was close, I went back to grouping and ended with a 2 shot test group, as you see next to #5.
Kriss Vector Reliability
The Vector has a reputation for being somewhat finicky, and I want to address that directly because it's one of the most common questions I get about the gun.
In my experience over approximately 1,500 rounds, I've had zero malfunctions. No failures to feed, no failures to eject, no light primer strikes. The gun runs. However, I've exclusively shot quality 230-grain ammunition through it, so I can't speak to how it handles lighter or oddball loads.
The concerns about Vector reliability seem to stem from two sources. First, some early Gen 1 models had issues that were largely resolved by Gen 2. Second, the unique bolt system creates anxiety for people who've never seen anything like it—the bolt traveling downward into the grip feels wrong until you understand the engineering behind it.
The Super V system is mechanically sound. It's been adopted by military and law enforcement units in various countries, which doesn't happen with unreliable firearms. The delayed blowback action is robust, and the Glock-pattern magazine interface is proven.
Long-term durability is the real question mark. Kriss claims the system is good for tens of thousands of rounds. Most reviews, including mine, are based on hundreds to low thousands of rounds, not the 10,000+ that would truly stress-test the design.
My take: the Vector is reliable enough for range use and home defense. I wouldn't bet my life on it without more personal round count, but that's true of any gun I haven't extensively tested myself. If you buy one and experience issues, Kriss customer service has a good reputation for making things right.
Range Bag
The Vector's unique recoil system deserves unique storage. The Bronx accommodates this 16" carbine and its distinct profile, and if you have a Multicam Black one like mine, you can order a made-to-order Bronx in Multicam Black.
Kriss Vector for Home Defense
The Vector makes a compelling home defense gun, though it's not without caveats.
On the positive side, the compact size and low recoil make it easy to maneuver in tight spaces and fast to get back on target if follow-up shots are needed. The Super V system genuinely reduces muzzle rise, which matters when you're shooting indoors under stress. A 45 ACP or 10mm Vector delivers more energy than a handgun while remaining controllable enough for anyone in the household to shoot.
If you add a suppressor—and I strongly recommend it for home defense if you're in a state that allows it—the reduced noise helps preserve your hearing during an indoor shooting event. Even with supersonic ammo, a suppressed gunshot is less damaging to your ears than an unsuppressed one in an enclosed space.
The downsides are mostly practical. At around $1,500 before optics and accessories, the Vector costs significantly more than a quality shotgun or AR pistol. The Glock-pattern magazines are reliable, but 13 rounds of 45 ACP isn't a lot if you're concerned about capacity. And while pistol calibers are adequate for self-defense, you're giving up the terminal performance of rifle rounds.
Would I choose the Vector over an AR-15 for home defense? Probably not, if we're being purely practical. But I do keep my Vector in a home defense role because it's the gun I shoot best under stress, and that matters more than theoretical ballistics. A gun you're confident with beats a "better" gun you're not comfortable shooting.
Final Thoughts
Is the Vector a practical firearm?
Yes and no.

I love shooting the Vector at the range. It's a fantastic gun that's fun and looks awesome.
Does it have a practical application?
Yes, any application a pistol caliber carbine could have the Kriss Vector would work for.
I like the Kriss as a home defense gun for several reasons.
However, it does have its limitations, such as the range and terminal ballistics of handgun caliber rounds.
There are some claims about the Vector's longevity, but after a year of ownership, I haven't had any issues with it.
The Policy backpack carry insert is purpose-built for transporting compact firearms like the Kriss Vector in any standard backpack.
It comes down to whether the Vector does what you want it to do.
