[1/3] A prototype of the Biofire Smart Gun is seen at Biofire Technologies headquarters in Broomfield, Colorado, U.S., April 18, 2022. Biofire's gun can also be enabled by a fingerprint reader, one of several smart gun features designed to avoid accidental shootings by children, reduce suicides, protect police from gun grabs, or render lost and stolen guns useless. That could make it the first commercially available smart gun in the United States since the Armatix briefly went on sale in 2014. At least two other American companies, LodeStar Works and Free State Firearms, are also attempting to get a smart gun to market. Many gun enthusiasts have become skeptical of smart gun technology, concerned it will fail when a weapon is needed for self-defense at a moment's notice.
