Well, we males have “guns,” but the wimmin, theyse got cannons !
find yourself a remington 870 home defense HD model pump shotgun in 20 ga.
It should have a capacity of about 5-6 shots.
Most of these models come with an 18-inch barrel.
You can usually find one at a well stocked gunstore for around $350.
Id also sign up for an NRA certified training course, or get some instruction from a local self defense instructor or a police officer you can trust.
My mother..for instance, has a 20 ga mossberg that I cut the barrel off to 18.5 inches. She and my father keep that around as their main home defense gun. She has a 22 caliber smith and wesson Kit Gun loaded with CCI stings (6 shot 3 inch stainless J frame revolver) while my dad has a J frame chief’s special snubby which he carries everywhere. In addition he has his Colt Gold Cup 45 auto and my 357 smith and wesson K frame revolver that is loaded with 38 special Cor Bon ammo.
