Adults under 21 years old can now obtain concealed carry permits in the Hawkeye State. On Friday, Republican Governor Kim Reynolds signed House File 924 into law. The legislation lowers the minimum age to legally carry a concealed firearm. It also lowers the age at which it becomes illegal to sell a used gun to another person. Both are now set at 18. “I joined the Marines when I was 18, I graduated from boot camp when I was 18. I was carrying firearms in the military, ready to defend my country when I was 18, along with hundreds of thousands of other young men and women,” Republican Representative Steven Holt, who sponsored the bill, told The Des Moines Register. “So the idea that an 18-year-old, a 19-year-old, a 20-year-old, doesn’t have a right to own a firearm in protection of their families—which is really what the Second Amendment is about, right?”
