Abstract: A safety lock device for lever action firearms. The safety device has two hardened side plates and transverse hardened pins. The safety lock device must be designed for each specific lever action firearm onto which it is intended to be used in order to insure the most secure fit and the highest confidence in the inability for disabling the device once installed onto the firearm. The combination of the hardened pins and a trigger channel and a separate lever channel for the open lever provide protection against the disabling of the lever action safety lock device.

Abstract: A firearm trigger locking device with two sides and fixed hardened steel pins. The device is designed to be universal for a particular family of guns—e.g., all rifles, all shotguns, or all handguns (or all revolvers or automatic pistols)—of a given firearm manufacturer. The device further features a pin behind the trigger to prevent firing, hardened steel plates in each side sufficient in size to cover the trigger guard and prevent transverse application of a saw to the trigger guard, and a ring of hardened steel pins around the periphery of the trigger guard to prevent application of a saw between the plates. The method for producing this trigger locking device uses lateral and axial profiles of the family of firearms to develop features and feature locations that will allow it to be used with any member of the family of firearms.
