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 six high-capacity shotguns for 2019.
1. DP-12

The DP-12 is one of the high-capacity shotguns designed for the most discerning shooters who demand extreme firepower and require consistent reliability.
The stock has a QR code you can scan with your smartphone or tablet to download the manual and other information. It also includes a lifetime warranty. (Be sure and fill out the warranty card and send it to Standard Manufacturing.)
The spreader choke tubes are designed to shoot a devastating pattern at 25 yards. The choke tubes have Tru-Choke thread patterns. (Breeching style chokes are sold separately.)
The DP-12 provides accessory rails and slots that allow you to customize it with your own accessories. Please see our website to select your accessories: lights, lasers, sights, scopes, muzzle breaks and more.

2. Kel-Tec KSG-25

The KSG ejects downward to clear the chamber and 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-25 by your side.

When I ordered the Desert Tan DP-12 and it came in Flat Dark Earth twice in a row the folks over at Standard Manufacturing informed me that the Desert Tan had been discontinued and were kind enough to fast track production of a Gold Edition equipped with the Aluminum Forward Grip with flashlight/laser, Red/Green reflex sight and Stiletto Chokes and matching harness. Absolutely love this weapon and it has effortlessly handled every custom load I’ve thrown through it. Now I’m just waiting on my IWI Tavor TS12 and my Charles Daly Honcho Tactical Triple to come in and I’ll consider my shotgun collection complete (for the moment at least)
I would like to buy a db12 shotgun. Is there a place i can contact for the finacing.
Absolutely love my Standard Manufacturing Company DP12 and my KSG 25!! Of course I love my Saiga 12 gauge too, but I might get that UTAS UTS-15 next cause it looks like it would be bada$$ too!!
I stick with my tried and true mossberg 590A1, battle proven very reliable and one of the few weapons adopted for use by the military that has stood the test of time.
Is it just me, or does the ksg look like it belongs in a Mad Max movie? Capacity yes, looks great…not so much.
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
How the Hell can you NOT mention the UTAS-15?! This shotgun clearly belongs in the Top 5. I have yet to see a MKA 1919 work without a single malfunction!
Good point. I knew I forgetting something… ~Dave Dolbee
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.
Amen Brother! Stay safe out there… ~Dave Dolbee
