Various types of guns are suitable for home defense depending on the situation, according to Guns & Ammo. These include semiautomatic handguns, revolvers, shotguns and rifles in a variety of calibers.
Semiautomatic handguns are excellent home defense guns, says Guns & Ammo. Revolvers hold less ammunition, but are easier to use and more reliable. Rifles and shotguns are effective weapons, but have drawbacks. Rifles and shotguns require two hands to use and are usually less accessible than a handgun. Popular models in all these categories include the Glock 19, Ruger GP100, Mossberg 500 and Ruger SR-556, according to Chuck Hawks.
