As the @thedivineinfidel said
Look at this chart @prokybrambora :
Look for the category open carry/concealed carry. Shall issue means that you have the right to be armed for self defense, like in the Czech Republic. May issue means that you don’t have the right but might be allowed to carry for self defense. May issue/restricted means that the theoretical possibility of a citizen being allowed to carry firearm for self defense exists in law, but is in reality impossible (like Charb, the editor-in-cheif of Charlie Hebdo, who was a sport shooter, owned a pistol, was getting daily death threats/had past attacks against him/paper committed, but whose application for concealed carry license was not approved).
Personal protection means that you can own a firearm for self defense, but only keep it at home (like it is currently in Slovakia).
