Choosing a home defense gun in Arizona

The best home defense gun is one you can store safely, reach fast and shoot well. This guide compares the main options for Arizona homes. It is general information, not legal advice.

The pistol

A full-size or compact 9mm pistol with a weapon light is the most practical choice for most homes. Glock-pattern pistols, whether factory or built on a serialized frame with quality parts, are popular because parts and holsters are everywhere. Test any pistol thoroughly before you trust it.

The carbine

An AR-15 or a 9mm carbine is easy to shoot accurately with light recoil and a red dot. It is larger to store and harder to maneuver in hallways.

The shotgun

A 12- or 20-gauge pump with buckshot is powerful and simple. It recoils harder and holds fewer rounds.

Storage

Keep a home defense gun in a quick-access safe, and lock up every other gun, especially if children live in or visit your home.

Arizona law

Arizona has a castle doctrine and no duty to retreat where you are lawfully present. The law allows deadly force in defined circumstances, including to prevent certain violent crimes in your home, but every case is judged on its facts.

Practice

Practice at an AZGFD-supported range, run drills with dummy rounds, and plan with your family.

Shop pistols, rifles and shotguns, and read the concealed carry guide.
