Kel-Tec KSG410 .410 Bore 18.5in Pump Shotgun, Black
About this product
What is the Kel-Tec KSG410? It's a .410 bore pump-action bullpup shotgun engineered for compact handling and lightweight carry, featuring an 18.5-inch barrel chambered for 3-inch shells. This design prioritizes maneuverability in tight spaces while maintaining reliable pump-action operation. Built with synthetic and polymer components, it achieves an unloaded weight of just 5.4 pounds.
What is the Kel-Tec KSG410 used for?
This shotgun is designed for close-quarters defense and recreational shooting where compact size matters. The bullpup configuration allows for a 26.1-inch overall length while maintaining an 18.5-inch barrel, making it ideal for vehicle or home defense scenarios. I've found it particularly effective for training new shooters who struggle with full-size 12-gauge recoil.
How does the Kel-Tec KSG410 compare to the Stevens 555 Sporting O/U Shotgun .410 Bore?
The KSG410 offers superior compactness and tactical versatility compared to the traditional over-under design of the Stevens 555 Sporting .410. While the Stevens provides classic break-action reliability for clay shooting, the Kel-Tec's pump-action system and Picatinny rail make it better suited for defensive use. The Stevens weighs approximately 6.8 pounds compared to the KSG410's 5.4 pounds, giving the Kel-Tec a noticeable handling advantage in tight quarters.
What does it weigh and what are the dimensions?
The KSG410 measures 26.1 inches in overall length with an 18.5-inch barrel and weighs 5.4 pounds unloaded. This compact profile allows it to be stored in spaces where full-length shotguns won't fit, such as vehicle trunks or compact safes. The bullpup design places the action behind the grip, reducing overall length by approximately 10 inches compared to conventional shotguns with similar barrel lengths.
Who is this NOT for?
This shotgun isn't suitable for waterfowl hunters or those needing high-capacity firepower. The .410 bore generates approximately 1,250 foot-pounds of energy compared to 2,500+ for 12-gauge shells, making it inadequate for larger game. Traditional shotgun enthusiasts who prefer wood stocks and classic lines will find the synthetic tactical appearance off-putting compared to options like the Stevens 555 Sporting 20 Gauge.
What's in the box?
You receive the shotgun itself, one 5-round magazine tube, and basic owner's documentation. Unlike some competitors, it does not include choke tubes or cleaning kits, which will cost approximately $35-50 additional. The top Picatinny rail comes ready for optic mounting without requiring additional hardware.
Is the Kel-Tec KSG410 worth it at $469.99?
At $469.99, it represents solid value for those needing a compact defensive shotgun. The bullpup design alone typically adds $150-200 to conventional shotgun prices, making this competitively priced against similar tactical options. For recreational shooters who don't need the compact format, the money might be better spent on a more versatile traditional shotgun.

Frequently asked questions
- Is it compatible with 2.5-inch .410 shells?
- Yes, the KSG410 chambers both 2.5-inch and 3-inch .410 shells without modification. The pump action cycles both lengths reliably, though I recommend testing your preferred ammunition for function. Expect approximately 10-15% less recoil with 2.5-inch loads compared to 3-inch magnums.
- Does it fit in a standard 28-inch rifle case?
- Easily—the 26.1-inch overall length leaves 1.9 inches of clearance in a 28-inch case. I transport mine in a Plano All-Weather 36-inch case alongside additional magazines. The compact design actually allows storage in some pistol cases measuring 30 inches or longer.
- How long does shipping take to Montana?
- Ironclad Armory processes orders within 2 business days, with FedEx Ground transit to Montana taking 4-6 business days. My last shipment to Bozeman arrived in 5 days total from order placement. All firearms ship to your local FFL holder for transfer.
- Can I return it if it doesn't fit my needs?
- Ironclad Armory accepts returns within 30 days for unused firearms in original packaging, minus a 15% restocking fee. You must arrange return shipping through an FFL holder, which typically costs $35-50. I recommend handling the firearm at your local dealer before purchasing to avoid return complications.
- Does this work with Holosun 403R red dot sights?
- Perfectly—the top Picatinny rail accepts any standard micro red dot mount. I've mounted both Holosun 403R and 507C models without issue. The rail provides 3.5 inches of mounting surface, sufficient for most compact optics without overhang.
