Best Home-Defense Shotgun Setup
Gauge, pump vs semi-auto, buckshot vs birdshot, and how to set up a shotgun for home defense — community-tested answers.
The Quick Take
A home-defense shotgun is devastating at across-the-room distances, but only if it's set up right. Start with a reliable pump (Mossberg 500/590, Remington 870) or a soft-shooting semi-auto (Benelli M4) in 12 or 20 gauge — 20 gauge is a legitimate, lower-recoil choice for smaller shooters. Load quality buckshot (00 or #1), never birdshot, which under-penetrates.
Add a weapon light so you can identify your target (non-negotiable), keep the gun cruiser-ready per your training, and pattern your specific gun with your chosen load at your actual hallway distance so you know your spread. The questions below cover gauge, pump-vs-semi, ammo, and sight choices from people who've set theirs up.
