Bullpup shotguns are quirky and eye-catching. They boast a couple of advantages too. In fact, a bullpup configuration naturally suits the role of a tactical shotgun well. A hypothetical home defense situation might demand the need for tight cornering, for instance, and a bullpup shotgun’s length is typically a little over half that of a traditional full-stock shotgun. Perhaps counter intuitively, a few shotguns on this list boast a high capacity (even higher than most traditional shotguns). As a result of their emerging capabilities, bullpup shotguns as a whole are expanding their market share of tactical shotguns. It’s worth noting they don’t sell well to hunters and skeet shooters (which probably is to be expected).

For some, home defense is a top priority.


In order to try and rank these guns, I’ve decided to use a typical home defense situation where you would need to shoot buckshot about 10-15 yards away as a metric. Other typical civilian situations seem to be better suited for traditional guns (except maybe simply showing off a new toy). Also, a disclaimer: all five of these shotguns were very similar in many categories. The distinctions that separate them are very tiny, and so the rankings had to be more subjective than I would’ve liked.

3: Mossberg 500/590 Bullpup

The Mossberg 500/590 bullpup edition will start the countdown at #3. These Mossbergs are 80’s movie stars, starring in Predator 2, the Running Man, and Robocop probably due to their futuristic appeal. Collectors should be on alert: their value is set to only rise, because there isn’t anything like them currently being manufactured by Mossberg. And, being a Mossberg, they carry a certain degree of intrinsic reliability.

Like reliability, there are more pros that aren’t just superficial…the Mossberg 500/590 bullpups are good shotguns, too. Even though the stock has a lot of gadgetry in it (as with most bullpups), it does really well to mitigate recoil. This attribute is in part due to being heavy, which could be seen as a con. They still boast an 18.5” or 20” tactical-length barrel. They are easy to clean and break down for whatever purpose. The pump action is smooth and makes a great intimidating (for some too loud) sound, and it comes with a nice grip.

There are, of course, some nitpicky cons that prevent it from being higher on the list. The sight is disappointing . Admittedly, you won’t need a good sight if the target is close enough. Admittedly, you can change the sight to any one that you wish if you know your way around a gun. However, I don’t think I’m crazy when I think that a sight doesn’t need to double as a carrying handle. Personally, I don’t value a carrying handle enough to start sacrificing optics. There have been vast improvements in optics since the gun came out in the 80's, so my critique might be a little unfair.

Anyway, moving on, here is a list of other cons:
Annoying and unnecessary grip safety (there’s another safety on the trigger)
Heavy by any standard
Long/heavy trigger pull, although not unreasonable
The Mossberg 500 has a low capacity relative to others on this list (5+1), 
although the Mossberg 590 has a better capacity (8+1).
High cost because they’re pretty hard to find
Ejection port is going to be on the right side next to your face (and literally 
in your face as a lefty, so lefties can’t use it).

The Mossberg conversions are still very good weapons, and there isn't much that separates them from #1 on this list.

2: UTS-15

Number two on the countdown is the Turkish UTAS UTS-15. I’m not sure why they didn’t go ahead and just call it the UTAS-15, they were only one letter short. Anyway, it’s a gun that immediately catches the eye (perhaps the word ugly comes to mind, but I prefer the term eye-catching). The UTS-15 has a lot of cool features that makes it and immediate competitor in the bullpup shotgun market. If you haven’t heard of its maker UTAS, you probably aren’t Turkish. I hear UTAS is kind of a big deal over there.
With that being said, it’s not a brand that I would immediately trust simply out of lack of familiarity. As expected, most of the negative comments that I’ve seen have been about reliability. The sources that I trust more seem to agree that it is in fact reliable. Nevertheless, I would recommend trying the gun out as much as possible before buying. Reliability is why I’m timid to rank this gun higher. Well, reliability and these small cons:

Loud when moving. No choice of pump grip. The grip it comes with is frighteningly 
slippery, especially (potentially) when wet.Speaking of that, in my opinion, there 
isn't enough guard to prevent a hand from slipping in front of the muzzle. Like 
the Mossberg and Remington it only ejects to the right side, next to your face 
Expensive in that most go for over $1300, and you’re going to need to add a sight 
Relatively bulky

With all of those cons, does it really deserve a high place on this list? I 
believe so, for two main reasons. For one, it holds 12+1 2 3/4" 12 gauge ammo 
and 14+1 3" ammo. That’s a ton. There aren’t a lot of situations where that 
isn’t enough to get the job done. The second reason compliments the first. 
The UTS-15 feeds from two different barrels, and UTAS designed a selector 
switch that allows you to choose which barrel to feed from. Not only is it nice 
to be able to choose what type of ammo you want, but also you’re given the choice 
to alternate between the barrels. Also, one feeding barrel is selected and then 
emptied, the UTS-15 automatically switches to the other barrel. The selector 
feature is unique and offers quite a bit of versatility in a small package 
allowing you to potentially choose between two different types of ammunition 
on the fly.

There are a few smaller pluses as well. The UTS-15 is incredibly light and 
durable because it is manufactured with state-of-the-art materials. It can 
optionally come with a built-in flashlight, laser, or an attachable extended 
barrel. The extended barrel could be handy if you wish to shoot skeet. It wouldn’t
be anyone’s first choice for a clay gun, but it might be kind of a fun one to
take to the range. It has rails to attach a sight, and like I said before you'll
probably need to do that. Lastly, it's easier to reload than the other pump
shotguns.

And with that, we move to #1...
Numero uno: The Kel-Tech KSG shotgun
https://vayserarms.com/firearms-in-stock-shotguns.html#!/Kel-Tec-KSG-12-Tactical-Shotgun-Titanium/p/48138488/category=12498162

The KSG is Kel-Tech's first shotgun, and it set the a good standard for bullpups. I must admit I get a little swoony over it, so I must ask that you bear with me. The KSG started as a curiosity for most gun owners but it has earned some enthusiasts since it came out in 2011. Unfortunately, demand is high and they have gotten very pricey.
Finally, we come to a bullpup that ejects downward, making it 100% ambidextrous. This wouldn't be such a big deal if the conversion kits and UTAS were more accepting of lefties, but when comparing it to other guns on the list downward ejection seems like a luxury. Also, at the range the KSG is more pleasant simply because there is less heat and smoke in your face.
You want capacity? You have capacity. The KSG can hold 7+7+1 rounds, meaning it has two feeding tubes that hold seven rounds each and of course you can chamber a round. Like the UTS-15, this means that you can have 7+1 rounds of one type of ammo and 7 rounds of another, and quickly choose between each whenever you desire. Also, there's a handy slide release on the trigger.
What really sets the KSG apart for me however is its lightness and compactness. There isn't a shotgun off the top of my head that I would rather have in tight corners or spaces. It doesn't look or feel like it should have 14 round capacity or an 18.5" barrel. Thus it is a true representation of what a bullpup shotgun should be. Plus, it looks pretty sexy. The most similar gun, the UTS-15, is bigger than the KSG but I don't like the feel as much, and you don't get anything (except for a selector switch mode) that the KSG doesn't offer. There are pictures of the KSG everywhere for good reason.
It's also pleasant to have rails. Like any of these bullpup guns, if you're used to shooting traditional shotguns you'll probably have trouble at first. The KSG can be fitted with any optics you desire to fix this problem, and you can add things like a grip guard and other accessories to the bottom.
The overall package is just a fun and reliable shotgun. When the KSG is laid out on a table next to other guns, it's hard not to pick it up first. Hopefully Kel-tech will come out with another model and/or there will be more shotguns like it in the future. For a first gen model, they knocked it out of the park.
