Abstract

A universal firearm locking assembly prevents unauthorized access to a trigger of a firearm. The firearm locking assembly includes a first side member and a second side member which pivot relative to each other about a pivot member. A locking mechanism locks the first side member relative to the second side member after the side members are clamped around the trigger and a trigger guard of the firearm. The locking mechanism includes a spring which is wound around the pivot member with enough force to prevent relative motion between the spring and the pivot member. The spring is secured to one of the side members and the pivot member is secured to the other. An access code input into the circuitry via a keypad will unlock an unlocking plate which can then be rotated to release the spring from the pivot member allowing them and the side members to move relative to each other.
