An automatic weapon safety system where power consumption is reduced an d safety is increased is disclosed. The system includes a movement detector operatively associated with the handgrip of a weapon for detecting the presence of a hand on the handgrip. The system also has a transceiver operatively associated with the movement detector for sending a coded signal when the weapon has been gripped. The coded signal is received by at least one remote token whic h receives the coded signal and transmits a coded acknowledgement signal upon receipt of the coded signal. A system is provided for enabling and disabling the weapon, operatively connected to the transceiver for allowing operation of t he weapon when the coded acknowledgement signal has been received. The system may include two tokens, which are worn by the authorized user. In this case, the transceiver further includes an anti-collision module to discriminate betwee n the different tokens and select which one will be permitted to issue the coded acknowledgement signal. Also preferably, the transceiver includes an anti- jamming module. Verification of the token can be done every time the trigger is depressed. Alternately, verification can be done only once, when the weapon is first gripped, and authorization remains until the handgrip is let go.Furthe rmore, since bi-directional RF communication is effected only when the trigger is depressed, power consumption is reduced.
