A Smart Gun Is Finally Here, But Does Anyone Want It?

A mass shooting during his teen years left Biofire’s Kai Kloepfer determined to make a safer handgun. Now the entrepreneur faces his moment of truth.

In an office parking lot about halfway between Denver and Boulder, a former 50-foot-long shipping container has been converted into a cramped indoor shooting range. Paper targets with torsos printed on them hang from two parallel tracks, and a rubber trap waits at the back of the container to catch the spent bullets. Black acoustic-foam padding on the walls softens the gunshot noise to make the experience more bearable for the shooter, while an air filtration system sucks particulates out of the air. It’s a far cry from the gleaming labs of the average James Bond movie, but Q might still be proud.

The weapons being tested at this site are smart guns: They can identify their registered users and won’t fire for anyone else. Smart guns have been a notoriously quixotic category for decades. The weapons carry the hope that an extra technological safeguard might prevent a wide range of gun-related accidents and deaths. But making a smart gun that’s good enough to be taken seriously has proved beyond difficult. It’s rare to find engineers with a strong understanding of both ballistics and biometrics whose products can be expected to work perfectly in life-or-death situations.
