A proximity alarm for a firearm having a trigger and a trigger guard is disclosed. The proximity alarm is for detecting when an object, such as a user's finger, enters the space between the trigger and the trigger guard, whereupon the proximity alarm alerts the user and any surround individuals that the object is in a position to depress the trigger to fire the firearm. An embodiment for mounting the proximity alarm onto an existing firearm is disclosed, as well as another embodiment wherein the proximity alarm is incorporated into the firearm itself to form a total firearm safety system. In the first embodiment, the proximity alarm includes an enclosure mounted proximate to the trigger guard of the firearm. The enclosure includes a firearm mounting means and at least one proximity sensor cooperating in such a way that an included proximity sensor is positioned to detect the object entering between the trigger and the trigger guard. The proximity alarm further includes an alarm circuit electrically connected to the proximity sensor and housed in the enclosure or, in the embodiment wherein the proximity alarm is incorporated into the firearm, within the firearm itself. The alarm circuit includes a power source, such as a battery, and an alarm means, such as an audio alarm, a visual alarm, or a tactile alarm. The alarm means may further include a wireless transmitter that transmits an alarm signal to a remote alarm unit for remote monitoring of the firearm.
