Allen Universal Trigger Trigger Gun Lock

The Allen Universal Trigger Gun Lock is a straightforward mechanical security device designed to prevent unauthorized firearm discharge. This universal trigger lock fits most handguns and revolvers, making it a practical choice for securing firearms during storage, transport, or when leaving firearms unattended in vehicles or homes. The lock is engineered to block trigger access while remaining simple to install and remove by authorized users with the included key.

Installation requires positioning the lock's two sides around the trigger itself, with the post secured behind the trigger. Once the included security screw is tightened using the key tool, it seats flush with the lock body—eliminating any protrusions that might catch on holsters or gear. The mechanism is optimized for triggers positioned toward the rear or middle of the trigger guard, though it is not suitable for lever-action rifles. The lightweight design (0.06 lbs) adds negligible weight to firearms or storage systems, making it practical for duty stations, safes, or field applications where quick-deploy capability must be balanced with physical security.

This trigger lock addresses the core duty of any responsible firearm owner: preventing accidental or unauthorized discharge. Law enforcement personnel, military operators, and civilian shooters rely on mechanical trigger locks to meet storage compliance in jurisdictions that mandate secured storage when firearms are not in active use. The universal fit eliminates the need to purchase multiple locks for arsenals containing different handgun models, reducing overhead while maintaining consistent security across platforms.

Trigger locks serve as a first-line mechanical deterrent—distinct from safes or locked cases, they work independently and can be deployed on any firearm regardless of location, making them an essential component of any comprehensive security strategy.
