ABSTRACT:
A safety alarm for a weapon such as a hand gun is provided that is mounted in the hand grip of the weapon to warn of possible impending use by either an authorized or an unauthorized person. The safety alarm is mounted within the hand grip and has an alarm connected electronically to a battery in a normally open circuit that is closed only when a switch within the circuit is activated. In one embodiment the switch is in the form of a plunger that extends outside of the grip and is engaged by the hand to be depressed to connect two electronic contacts to complete the circuit and sound the alarm. In another embodiment the switch is in the form of a motion detector such as a mercury switch so that when the weapon is moved from one position in which the circuit is normally opened, the circuit is closed to connect the alarm to the battery and sound the alarm.
