Abstract: A firearm safety apparatus is provided that includes two or more locking arms or coverings connected by a hinge and configured to engage a trigger guard of a firearm, in a closed position preventing access to the trigger. A locking mechanism retains the arms in a closed position until opened by an activation signal. A firearm safety apparatus is also provided that includes a housing connected to a firearm. A trigger guard cover is slideably or hingably connected to the housing. A locking mechanism is coupled to the trigger guard cover to surround a trigger of the firearm until an activation signal is received. The locking mechanism exposes the trigger through a hinged or slide motion. The housing is amenable to inclusion of various tactical accessories such as a light source or a camera.
