SigSauer pistol with concealed radio transmitter
First Claim
1. A SigSauer pistol having:
- a hollow metal handle body of generally rectangular cross-section with a front wall, a back wall, and opposite side walls with respective openings therein, said handle body having a longitudinal cavity between said front, opposite side and back walls which is open at the lower end of said handle body for the slidable insertion and removal of a magazine casing for holding bullets;
a plastic grip having a back segment on the outside of said back wall of said metal handle body and side segments on the outside of said side walls of said metal handle body covering said openings in said side walls;
said back segment of said grip having a shallow recess which is open at the front of said back segment;
an antenna assembly received in said recess, said antenna assembly including a radiating element;
one of said side segments of said grip having a shallow recess which is open at the inside of said one side segment and registers with said opening in the corresponding side wall of said metal handle body;
an insulation panel received in said recess in said one side segment of said grip, first and second spring contacts on said insulation member, said contacts being exposed at the inside of said one side segment of said grip and projecting through said opening in the corresponding side wall of said metal handle body, said first contact being conductively connected to said radiating element of said antenna assembly, and insulated electrical wires connected conductively to said first contact and extending outside said recess in said one side segment of the grip;
a hollow magazine casing slidably insertable into and removable from said longitudinal cavity in said metal handle body through said open lower end, said magazine casing having a front wall, opposite side walls and a back wall, a pair of electrical contacts on the outside of one of said side walls of the magazine casing for engagement respectively with said spring contacts when said magazine casing is fully inserted into said longitudinal cavity in said metal handle body;
a false bottom in said magazine casing spaced above the lower end of the magazine casing, a spring-operated follower slidably received in said magazine casing above said false bottom for pushing bullets up along the magazine casing;
said magazine casing having a chamber below said false bottom, battery switch contacts in said chamber for engagement by battery terminals, and a radio transmitter and microphone in said chamber having electrical connections to said battery switch contacts and said electrical contacts on the outside of said magazine casing.

Abstract
A SigSauer pistol is modified to hold on the inside of its plastic handle grip an antenna assembly and spring contacts connected conductively to the antenna assembly. A modified magazine casing in the handle of the pistol has a chamber below a false bottom for receiving batteries and a printed circuit board carrying a radio transmitter and microphone. Electrical contacts on the outside of the magazine casing engage the spring contacts on the inside of the handle grip when the magazine casing is slidably inserted into the usual metal handle body on the pistol. Corresponding contacts on the inside of the magazine casing engage contacts on the printed circuit board that are connected electrically to the transmitter. Downwardly-facing battery switch contacts in the chamber are connected electrically to the transmitter and are positioned to engage respective terminals of two series-connected batteries.
