The Kel-Tec KSG is a 12-gauge pump-action shotgun built on a bullpup layout that keeps the overall length to 26.1 inches while running a full 18.5-inch barrel. Its dual magazine tubes hold 14+1 rounds, so you can carry two different shell types and switch between them at the selector.

Detailed Features 

 
The bullpup configuration places the action behind the trigger group, cutting overall length without shortening the barrel. That geometry changes weight distribution noticeably compared to a conventional pump, so new owners typically need a few range sessions to get comfortable with it. 
 
The dual-tube magazine is the KSG's defining feature. Each tube holds seven 2.75-inch shells, and a cross-bolt switch routes feeding from one tube to the other mid-session. A cross-bolt safety handles safe/fire, and the receiver is drilled for Picatinny-style accessories. The flat top will accept optics, lights, or a foregrip. 
 
Build materials are a mix of synthetic polymer furniture and steel internals. The tan-finish stock resists weathering well. Feeding reliability depends on the pump stroke being completed fully; short-stroking under stress is the most common complaint with any bullpup pump.

The KSG draws strong interest because the 14+1 capacity and bullpup compactness are genuinely hard to match in a pump gun. Most owners who put time into learning the manual of arms come away satisfied. The dual-tube setup is praised for letting hunters or home-defense users stage different loads: buckshot in one tube, slugs in the other.

On the critical side, the weight distribution feels front-heavy to shooters used to traditional stocks, and a few report feeding hiccups when the pump is short-stroked under pressure. The grip and controls can feel cramped for large hands, and the lack of iron sights means you need to budget for an optic or rail-mounted irons. These issues tend to smooth out with practice, but beginners should expect a steeper learning curve than with a conventional pump.

Compact and maneuverable, mine cycles both mini shells and standard shells.
