Description
There's nothing else on the market quite like the KSG410. KelTec took the dual magazine tube layout from their famous 12 gauge KSG, scaled it down to .410 bore, and borrowed the bright fiber optic sight setup from the KS7. The result is a bullpup pump gun that measures just 26.1 inches from end to end, runs an 18.5 inch barrel, and weighs only 5.4 pounds empty. This version wears an OD Green finish that gives it a subdued, field-ready look without giving up any of the tactical DNA.
Big Capacity in a Small .410 Package
Each magazine tube holds five 3 inch shells, giving you 10+1 on board, and switching to 2.5 inch shells bumps that up to 14+1. A selector lever behind the pump lets you choose which tube feeds, so you can stage buckshot in one and birdshot in the other, then swap on the fly. The action ejects straight down, which makes the gun fully ambidextrous, and at just 1.7 inches wide it tucks into tight hallways, truck cabs, and gun safes with ease.
Why the KSG410 Makes Sense for the Whole Family
The .410 chambering is the real story here. Recoil is genuinely mild, which makes this a pump gun that smaller-framed or recoil-sensitive folks can run confidently, and the pump action digests just about any shell you feed it. With modern defense-grade .410 loads widely available these days, it fills a smart niche between a full-power defensive shotgun and a handgun. Picatinny rail up top gives you room for an optic, the bottom rail accepts a light or vertical grip, and built-in sling loops round out the package.
Living With the KelTec KSG410
The checkered polymer furniture holds up to rough handling, the 13 inch length of pull fits a wide range of shooters, and the roughly 5 pound trigger is respectable for a working shotgun. Whether it ends up on pest control duty, by the nightstand, or just turning heads at the range, this one earns its spot.

Frequently Asked Questions
How many rounds does the KSG410 hold?
The KSG410 uses dual magazine tubes that each hold five 3 inch shells, giving you 10+1 total capacity. If you run 2.5 inch shells instead, capacity jumps to 14+1. A selector lever lets you pick which tube feeds, so you can load different shell types in each side.
Is the KelTec KSG410 good for home defense?
It's a strong candidate. The 26.1 inch overall length and 1.7 inch width make it easy to maneuver indoors, and the mild .410 recoil means just about anyone in the house can handle it. Modern defensive .410 loads have come a long way, and the double-digit capacity gives you plenty on tap.
Is the KSG410 left-hand friendly?
Yes. The bullpup action ejects spent shells straight down rather than out the side, so the gun runs the same way for right and left handed users. The controls are laid out symmetrically as well, making it a fully ambidextrous design.
Can I mount an optic or light on the KSG410?
You can. There's a Picatinny rail on top for a red dot or other optic, plus a bottom rail on the forend for a weapon light or vertical grip. It also ships with a fiber optic front sight, so it's usable right out of the box before you add anything.
