The ATF has issued an officer safety advisory on what is called the world’s smallest gun after a CBS 2 inquiry. The Alert has been issued both in the New York and nationally to all Alcohol, Tobacco, Firearms and Explosives criminal investigators and will be passed on to other federal agencies. The ATF has confiscated thousands of disguised or miniature guns from flashlights that shoot a .25 caliber bullet to pen guns. The latest miniature gun that is alarming the ATF community is the Swiss MiniGun.
