KelTec KS7 Review: Will this replace your current home defense shotgun?

by Travis Pike

May 2, 2024



KelTec is well known for its odd and innovative designs, and today, we’ll be shooting their bullpup shotgun. No, not the KSG. We have hands-on with the KelTec KS7. Let’s see if innovation equals a good scattergun in this KelTec KS7 review.

So, I originally reviewed this shotgun last year but after a few hundred rounds with it, my opinions have somewhat changed. Let’s take a look at this updated review to see what’s different.

The KelTec KS7 – Keeping It Simple

As a former Marine, I’ve had my fair share of experiences with firearms, and KelTec’s innovative yet sometimes hit-or-miss designs have always piqued my interest. In 2011 KelTec introduced a very odd shotgun. It was a bullpup design with two magazine tubes. This gave the shooters an impressive 14 rounds of 12 gauge ammunition. While neat, it’s big, heavy, cumbersome, and a bit complicated. Admittedly even as a shotgun nerd, it wasn’t for me. A few years later, KelTec released the KS7, a simplified version of the KSG. 

The KS7 retained the bullpup layout but moved from a dual tube format to a simplified single tube magazine design. They made a few other revisions, namely the eye-catching carry handle sight setup. It gives the KS7 a retro space force look to it. That carry handle contains your sight as well as some M-LOK slots. 

A simplified design lowers the weight and the price significantly. At only 5.9 pounds, it’s a very light and handy gun. Additionally, the bullpup layout ensures a short overall length. In fact, it’s only 26.1 inches long. For reference, that’s shorter than a Mossberg Shockwave. The KSG would typically cost close to a thousand bucks, but the KS7 is about half that. 

The KelTec KS7 holds seven rounds of 2.75-inch shells and can chamber 3-inch shells as well. That’s not a bad deal for such a small and lightweight shotgun. The KS7 is a little odd but looks to be a very effective shotgun, or at least it could be. KelTec historically has had some QA problems. 

Will these issues plague the KelTec KS7?

Models and Variations of the KelTec KS7

There are a few different color variations of the KelTec KS7. Here are 3 variations you may want to consider.

KelTec KS7 Review – Our Take

One thing you have to do with the KS7 is toss out most conventional shotgun knowledge. You’ll have to relearn a few things when it comes to the KS7. The KelTec KS7 still requires you to know how to shoot a shotgun, though, especially when it comes to recoil mitigation. You need to exercise a good push/pull technique, or the gun will beat you up! 

KelTec KS7 Patch

Recoil can be sharp with full powered loads. Additionally, you’ll need to watch your thumb on the pump. My thumb naturally points toward the target when holding the gun’s pump. The KS7 has a hand stop built into the pump of the weapon. My thumb would rest on this hand stop, and when I fired, the recoil would thump my thumb. I had to curl my thumb up to prevent this. 

I would have liked an M-LOK slot or rail on the pump somewhere to mount accessories, but that’s not an option, sadly. A vertical grip on the pump would make shooting it much more comfortable. 

The short and light design makes the gun easy to handle and easy to get on target or to transition between targets. There is no weight to swing around. Just turn your body and the gun points where you want it to. Ergonomically it’s a sound design. It works for righties or lefties due to the downward ejection and ambidextrous nature of the controls. 

Loading can be a little awkward, but everything else flows well. I especially like the short length of pull. It makes it easy to assume a good squared-up shooting position and to let the lead fly.

Throwing Lead 

The big triangle-shaped fiber optic sight is easy to see and quick to get on target. Buckshot and slugs are varying types that went exactly where I wanted them to. The point of impact and point of aim aligned perfectly.

KelTec KS7 Damage

The M-LOK rails below the sight offer you a place to mount a light. With that said, somehow, in between shooting the gun and transporting it to the range, the M-LOK slot I had a light attached to broke. Now my carry handle is broken, and that’s likely due to its plastic nature. I plan to replace it with an optics rail now. There is no provision for optics from the factory. 

Outside of that M-LOK rail breaking, I have zero reliability issues. The gun eats high brass, low brass, birdshot, buckshot, and slugs without complaint. The gun does not function with short shells, but that’s not a problem for me. Those are nonstandard shells. The gun never failed, jammed, or double-fed. It just went bang. 

I’ve heard of short stroking issues with this gun, but that’s on the user. It’s not any easier to short-stroke this shotgun than any other. You just need more practice and training to avoid it. 

Price-wise, it’s a little more expensive than a bare-bones 870 or Mossberg 500. That can be a detraction for some. Both of those guns have decades of proven service and a massive aftermarket to support them. The KS7 does not have that prestige.

I really enjoy shooting the KS7. It’s just so different from other shotguns I own. Add in the fact it’s smaller than most short-barreled shotguns, and you get seven rounds, and that’s just the cherry on top.

KelTec KS7 Side View

KelTec KS7 Pros and Cons 

  • Weight – Ultra Light
  • Size – Short and Compact
  • Reliable – Never failed, jammed, or double-fed
  • Fragile Rail – Ours broke in transport and testing
  • Ergonomics – Can Have a Painful Thumb Bump

Report Card


Recoil can be stiff. A sub-six-pound shotgun will do that to you. You really need to exercise a good push/pull recoil mitigation technique.


The gun eats what it advertises. It has zero issues with 2.75-inch and 3-inch shells. The gun fires, extracts, ejects, and loads without a problem. It gets a B due to the broken rail, which remains unexplained.


The point of aim and point of impact is dead on for advanced loads like Flitecontrol and slugs, and it works perfectly with buckshot, as you’d imagine. At shotgun ranges, it does shotgun things and does them well.


The gun does have a lot of high points. Downward ejection makes it lefty friendly. The safety is easy to access, and the LOP is nice and short as well. The main downside is the painful thump your thumb can get if held naturally.


The KelTec KS7 doesn’t break the bank, and for such an interesting shotgun, it’s pretty darn affordable.

  1. I recently bought a KS7 and I’ve not had a single issue with 1.75″ slug shells. I put 40 rounds of mix Aguila and Federal mini’s and 20 rounds of Remington 2.75″ slugs. The rest were a variety 2.75″ buckshot. A little over a 100 rounds total without a problem on my first outing with it.

    I will say 1.75″ shot shells are disappointing in my 590’s in performance. Function was fine, but that’s all I can say.
