These veterans made a gun safety device that unlocks with a fingerprint

Two Air Force vets made a breakthrough in gun safety. They created an accessory that keeps pistols from firing in the wrong hands.

Dubbed the "Guardian," it uses fingerprint technology to unlock a gun's trigger by the owner. It attaches to most pistols without modifying the weapon and remains in place during use, making it quick and convenient to handle while serving its purpose.

It's similar to unlocking your mobile phone. After authentication via fingerprint, the Guardian unlocks allowing the slide to snap forward granting access to the handgun trigger:

Skylar Gerrond and Matt Barido set out to solve two problems with the Guardian: safety and immediate protection. The best practice with children at home requires firearms be locked away with bullets stored in a different location. But this could defeat the purpose of having a firearm ready at a moment's notice. To remedy this problem, some owners hide the weapon in an easy to access location, which can jeopardize safety. The Guardian solves both problems.

"That's the dilemma that drives people to taking the worse course of action — a loaded handgun, not secured at all, in a 'safe place' where [they think the] kids doesn't know about it," said Gerrond in an interview with The Blaze. "We wanted something that never actually left the handgun. The slide retracts forward in front of trigger guard, allowing access for you to physically insert finger into trigger well."

The Guardian's target price will be $199 when it becomes available. The creators are still in the prototype phase and are using Indiegogo to fund its development.
