New Mexico Gun Laws & Firearms Safety Practice Exam

What type of firearm safety mechanism requires a personal identification number (PIN) to fire?

1. Safety catch

2. Biometric lock

3. Trigger lock

4. Electronic lock

The correct answer is: Electronic lock

The correct choice is the electronic lock, which utilizes advanced technology to enhance firearm safety. An electronic lock typically requires a personal identification number (PIN) or another electronic verification method to unlock the mechanism before the firearm can be discharged. This feature is particularly beneficial in preventing unauthorized use, whether by children or others who may not have permission to access the weapon. While other options represent forms of firearm safety mechanisms, they do not specifically incorporate the use of a PIN for operation. A safety catch is a manual mechanism that prevents the firearm from being discharged until it is intentionally disengaged. A biometric lock uses unique biological traits, like fingerprints, for access but does not rely solely on a numeric code. A trigger lock is a mechanical device that physically blocks the trigger from being pulled without necessitating any electronic means or codes.
