Description
If you’re lookin’ for a compact, lightweight scattergun that handles like a dream in tight cover, the Kel-Tec KSG410 .410 Bore 18.5in Pump Shotgun, Black is a fine choice. This bullpup pump-action weighs just 5.4 pounds and measures a hair over 26 inches overall, makin’ it a natural for truck guns, snake charmers, and walkin’ through the thick stuff after doves. Chambered for 3-inch shells, it packs enough punch for small game without the heft of a full-size 12-gauge.

Key Features
- Bullpup Design – By movin’ the action behind the trigger, the overall length stays short while you keep a full-length 18.5-inch barrel. That means you get good sight radius and velocity without the long gun.
- Dual Tube Magazine – Two separate magazine tubes let you carry different loads — say, birdshot in one tube and buckshot in the other — and switch between ’em with a manual selector. Why it matters: you can adjust your load on the fly without unloadin’ the gun.
- Lightweight Construction – At just 5.4 pounds, this shotgun is easy to carry all day. Why it matters: less fatigue means you stay ready for that late-afternoon flush.
- Picatinny Top Rail – A full-length rail atop the receiver lets you mount a red dot, reflex sight, or open sights. Why it matters: you can dial in your exact point of aim, especially handy when usin’ slugs.
Who It’s For
The KSG410 is built for the shooter who needs a lightweight, compact shotgun for small game, pest control, or as a truck gun. It’s also a natural for younger or smaller-framed shooters who want a .410 that handles like a full-size gun. If you’re a dove hunter who likes to walk the edges of fields or a landowner keepin’ snakes and varmints at bay, this gun fits right in.
Pros and Cons
- Pro: Extremely compact and light — easy to maneuver in tight spaces.
- Pro: Dual magazine tubes let you carry two different loads.
- Pro: Picatinny rail accepts modern optics.
- Con: The bullpup design means the ejection port is close to your face, which can be a bit loud and dirty. Some shooters find it takes a little practice to get used to the manual selector between tubes.
Comparison: Kel-Tec KSG410 vs. Mossberg 500 .410 vs. Remington 870 .410
| Feature | Kel-Tec KSG410 | Mossberg 500 .410 | Remington 870 .410 |
|---|---|---|---|
| Action | Pump-action bullpup | Pump-action traditional | Pump-action traditional |
| Overall Length | 26.1 inches | ~42 inches (with 18.5-inch barrel) | ~44 inches (with 18.5-inch barrel) |
| Weight | 5.4 lbs | ~6.5 lbs | ~7.0 lbs |
| Magazine Capacity | 6+1 (two tubes of 3 each) | 5+1 (tubular magazine) | 4+1 (tubular magazine) |
| Stock | Synthetic bullpup | Synthetic or wood | Synthetic or wood |
The KSG410 is significantly shorter and lighter than both the Mossberg 500 and Remington 870 in .410, and its dual-tube setup gives you more ammo capacity and load versatility. The trade-off is a less traditional feel and a learning curve on the tube selector.
Frequently Asked Questions
What shells does the Kel-Tec KSG410 accept?
It accepts 2.5-inch and 3-inch .410 bore shells. Stick with standard pressure loads for best reliability. Per Kel-Tec specs, the chamber is built for 3-inch shells.
Is the Kel-Tec KSG410 reliable for home defense?
Many shooters find the KSG410 reliable with quality shells. The bullpup design keeps it short for tight hallways, and the .410 with buckshot or slugs offers adequate stopping power. That said, pattern it with your chosen load to ensure function.
Can I mount a scope on the KSG410?
Yes, the top Picatinny rail accepts any standard scope rings or red dot mounts. Just be sure to use a low-profile optic to keep the sight line comfortable.
How do I switch between the two magazine tubes?
There’s a manual selector lever just behind the trigger guard. Push it left for the left tube, right for the right tube. The gun will feed from the selected tube until it’s empty.
