A federal appeals court has ruled that the ban on handgun sales to individuals under the age of 21 is unconstitutional. The decision by the 5th Circuit Court overturns existing federal law that restricted gun purchases for those aged 18 to 20, citing violations of the Second Amendment. This ruling is part of a growing debate over gun rights and regulations in the United States, as the court acknowledges the need for young adults to have access to handguns despite concerns over rising youth violence. The decision is likely to prompt further legal discussions and legislative actions regarding age limits for firearm sales.
