In order to achieve greater accuracy attempts have been made to secure laser pointers on police handguns. The difficulty is that they become dislodged and consequently produce inaccurate fire. Another solution is to place the laser physically in the bullet.
The bullet would have to be a hollow point. The copper jacket of the bullet would be 1 electrode. An insulator, perhaps Teflon tape, would be wrapped around the bullet for electrical separation. The 2nd electrode would be the propellant case. an electric conductor would be swaged between the Teflon tape around the bullet and the case. A plastic tube would be installed into the case to allow propellant to be filled while leaving a space to insert the laser light tube.
The electronic package for the bullet would be installed on the pistol frame. The battery could be installed at eh bottom of the bullet clip, displacing 2 or 3 bullets.
Grips would be squeezed on the front and back of the pistol handle to connect the circuit and activate the laser. If the circuit fails, the pistol would still be operable.
A serious difficulty is placing the electrodes in the pistol chamber. The negative electrode would provide electrons which is what oxygen wants for reactions, there would be a severe danger of corrosion unless the electrode is isolated from the steel . A ceramic insert could be used to achieve this. There is a danger of dislodgement and jamming.
At a muzzle velocity of 350 meters per second, the bullet would drop about 0.1 meter, 10 centimeters at 50 meters range. The light tube might also be slightly misaligned and the laser light would spread over some area. But it should still have effective accuracy at 50 meters, if the laser has adequate light to be seen, particularly under sunlight.
This would be a war crime for military usage since the bullet is open ended. The idea would be to have it available only for police agencies to insure that police have an advantage in gunfights. In the U.S., the lunatic lobby would insist on everyone haveing access to them, which would really be a bad idea since it would make killings much easier.
The pistol would be more expensive and the bullets many times more expensive than conventional designs.
