Works like a charm - IDENTILOCK GLK-A1 Biometric Trigger Lock for Glock

The set up is quick and painless. The device unlocks very quickly. I’ve tested it many times and it seems to work flawlessly. It does have to be charged periodically but you can register for reminders if you have difficulty remembering. I would highly recommend this product if you want close accessibility to your firearm and safety for your family.
