## Abstract

Systems for universally locking a trigger of a firearm are provided that require authentication to transition the firearm to an unlocked state. In general, examples of the systems for universally locking a trigger of a firearm described herein are located in an interchangeable grip portion of the firearm or mounted to an accessory rail of the firearm. Embodiments of the system generally include trigger interference or blocking members to prevent actuation of the trigger until the authentication system has authorized the user to fire the firearm. Once the system is authenticated, embodiments of the system remain in an unlocked state while the user is grasping the firearm. When the user removes their hand from the firearm, embodiments of the trigger locking system automatically returns to a locked state, reducing or eliminating unauthorized use of the firearm.

## Claims

### Claim 1

A firearm trigger locking system for a firearm having a trigger extending from a firearm body, the firearm trigger locking system comprising:
an authentication system configured for selectively locking the trigger, the authentication system comprising:
an actuator in communication with a central processing unit that is activatable by the central processing unit when an identification component recognizes a stored authorization key;
a trigger interference member moveable by the actuator between a first position, wherein the trigger interference member engages the trigger external to the firearm body and prevents movement of the trigger, and a second position, wherein the trigger interference member allows movement of the trigger;
a block moveable by the actuator from a first position to a second position when the identification component recognizes the stored authorization key, wherein the block abuts the trigger interference member in the first position to prevent movement of the trigger interference member within a slot for preventing actuation of the trigger; and
a continuous firing button configured to maintain the block in the second position while the continuous firing button remains depressed.

### Claim 2 (depends on 1)

The firearm trigger locking system of claim 1, wherein the block is moveable from the second position back into the first position when the identification component fails to recognize the stored authorization key to prevent movement of the trigger interference member within the slot for preventing actuation of the trigger.

### Claim 3 (depends on 1)

The firearm trigger locking system of claim 1, wherein the identification component comprises a radio frequency identification sensor configured to receive the stored authorization key from a separate component external to the firearm trigger locking system embedded with the stored authorization key.
