Abstract
A Browning high power pistol with a concealed radio transmitter. The wood side pieces on the hollow gun handle are recessed to hold a microphone and radio transmitter circuitry in one side piece and an antenna, including its ground plane, in the other. The usual magazine casing is modified to have a false bottom and a compartment below the false bottom for receiving a standard 9-volt battery. The usual spring-operated pusher for bullets is in the magazine casing above the false bottom. The wood side piece holding the battery and its ground plane support a pair of switch contacts that are engaged by switch contacts on the outside of the magazine casing when the magazine casing is fully inserted into the gun handle. These switch contacts, when engaged, connect the battery to the transmitter circuitry and the antenna.
