Abstract
An authorization system for a firearm (10) includes an authorizing device (32) worn by the authorized user, and a firearm (10) with a fire control system, a computer controller (28), and a piezo-electric disabler (60). The computer controller (28) communicates with the authorizing device (32), and if no authorizing signal is received from the authorizing device, sends an electric output signal to the disabler (60) to prevent the fire control system from allowing the firearm to fire. The disabler, upon application of the electrical signal from the computer controller, cams the rearward moving trigger bar (52) of the fire control system clear of the hammer link (54) to disrupt the fire control system. Consequently, the firearm (10) will not fire.
