I would even advocate this technology being integrated into the grip of the gun as a requirement of owning one.
IDENTILOCK for Glock
Works very well as advertised.
I have never used a trigger lock before so I don’t have anything to compare to. However,I am extremely pleased with my new trigger lock. It is exactly what is needed for the weapon I keep in my night stand.
This thing is awesome. I’ve tried my best to bypass it and it stays locked every time. Easy to set up, easy to use, I love the reminder to charge app. Got it for my wife so she could carry safely with our children.
Not having young folks 24/7, I've looked for a safety lock for pistol and think this is a great idea. But set-up instructions are lacking in finite detail … like using the override key & when to remove it, also setting a fingerprint. But it's made well.
