Under federal law it is a felony for anyone under 18 to possess a handgun. 18 USC 921. The federal Gun Control Act of 1968.
Yes. Federal law prohibits handgun sales by licensed dealers to persons under 21. Unlicensed dealers are prohibited only from selling handguns to persons under 18. Although Wisconsin state law imposes a minimum age of 18 for possessing long guns, there is no minimum age for handgun possession.
Right, wrong? I don’t know.
