<p>A firearm safety system is described herein which may be configured to be personalized for use by one or more individuals who are authorized to use that firearm. The firearm may have the one or more authorized individuals pre-authorized such that one or more of their biometric identifying information becomes associated with the weapon. During use, the firearm may readily identify whether the user is an authorized individual in which case the firearm may be used normally. In the event that the biometric feature of the detected user is an unauthorized individual, the firearm may become rendered unusable by automatically disengaging or inhibiting the firing mechanism.</p>
