I live in rural Illinois. I am thinking about buying a small gun for security. I am also going on a road trip with my family to Florida in March. Here are my questions: 1. Do I need any permit to own a .22 caliber pistol or a rifle in IL? What if I buy a 9MM pistol/rifle? 2. I know IL do not have concealed carrying permits, can I keep a .22 caliber handgun/rifle with me in my car when I go to unsafe neighborhoods? 3. What is the law on carrying a gun in the trunk while going out of state to FL? Advanced thanks for answering.
