Woman with double-barreled DP-12 semiautomatic shotgun

When it comes to high-capacity shotguns for self-defense, the old adage, “I’d rather have more ammo and not need it, than need the ammo and not have it” can be liberally applied. The DP-12, with its 16-round capacity, raised the bar, but manufacturers are again pushing the limits with magazine-fed shotguns and capacities reaching 25 shells. Here are our top five high-capacity shotguns for 2018.

1. DP-12

2. Kel-Tec KSG

Kel-Tec KSG shotgun, gray, profile right, high-capacity shotguns
The KSG is the innovative 12-gauge pump action shotgun from Kel-Tech!

Designed primarily as a defensive shotgun, the KSG-25 features a single 30.5″ barrel fed by two separate magazine tubes. A manual selector lever behind the trigger guard allows you to select which tube is feeding the hardened steel receiver. The KSG ejects downward to clear the chamber to give you more reliable operation when you need it most. The dual tube magazines hold an impressive 20 rounds of 3″ shells (10 rounds each), giving you some serious firepower.

The KSG will hold 24 rounds of 2-3/4″ shells (12 rounds each) and its simple, reliable action can cycle shells as small as 1-3/4″ if you want to hold even more shots. A familiar cross bolt-style safety, a pump release lever located in front of the trigger guard and the ability to clear the chamber without feeding rounds are important safety features in any home defense shotgun. The Zytel synthetic forend and pump have top and bottom Picatinny rails for mounting lights, optics and accessories. The synthetic stock has a nice thick soft rubber recoil pad to tame the recoil of this powerful shotgun. Take it to the range for shooting fun during the day and sleep peacefully at night with the KSG by your side.

  1. The biggest point of the KSG that they didn’t really point out is with the selector switch to go from tube to tube you can instantly change what round you want to use for the situation that you come to slugs for breaching the door birdshot for clearing a room

    1. Take heart Dave, no ones perfect. I doubt Mr. Singer is either. If he is, he should be careful. You all know what they did to the last “perfect” man.
