Choosing a home defense gun in Kansas

A home defense gun has one job: protect your family at close range, in the dark, under stress. The best choice is the one you can store safely and shoot well. This guide compares the main options for Kansas homes. It is general information, not legal advice.

The 9mm pistol

A full-size or compact 9mm pistol with a weapon light is the most common choice. It fits in a quick-access safe by the bed, leaves a hand free, and 9mm is affordable for practice. The Glock 17 and 19, SIG P320, Smith and Wesson M&P and CZ P-10 are proven choices.

The pistol-caliber carbine

A 9mm carbine or large-format pistol is easier to shoot accurately than a handgun, with light recoil and a red dot sight. It uses the same ammunition as your pistol and is quieter indoors than a rifle. See our Scorpion and PCC guide for the rules on pistols, carbines and braces.

The AR-15

A 5.56 carbine is light, accurate and holds 30 rounds. Defensive 5.56 loads fragment and often penetrate fewer interior walls than people expect, but every round must be treated as capable of passing through walls.

The shotgun

A 12- or 20-gauge pump loaded with buckshot is simple and powerful at indoor distances. It kicks hard and holds fewer rounds, and buckshot passes through drywall.

Storage

Keep a home defense gun in a quick-access safe with a keypad or biometric lock, and lock up everything else. Children and visitors should never be able to reach a loaded gun.

Kansas law

Kansas has a castle doctrine and a stand-your-ground law. A person may use force, including deadly force when justified, to defend themselves or others and to prevent an unlawful entry into a dwelling, place of work or occupied vehicle. Each case turns on its facts; a class on the use of force is worth the time.

Practice

Shoot at a public range on the KDWP list or an indoor range, practice reloads and malfunctions with dummy rounds, and plan with your family what everyone does at night.

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