When we talk about pistols, we usually mean the small firearms that people carry with them or use for hunting. You might hear someone say they have a pistol permit or that it's against the law to carry a pistol in public places. Some countries also have laws about how many rounds of ammo you can buy with a pistol, which is why some people prefer to own shotguns instead.
