Iconic Sci-Fi Gun: the Terminator's .45

True story: the making of the Terminator's laser-sighted .45 pistol via ars technica

This wasn't the first time Reynolds had put a laser on a gun. As early as 1978 he designed a laser sight for the Colt Trooper .357 Magnum. "It was a viable product out in the marketplace, primarily law enforcement. They were also very expensive, and we highly modified the weapon. We had to machine the frame and mounts; the sights were taken off the weapon to mount the laser on top. We designed a power supply that was smaller than a small candy bar and had to fit inside the grip, fed by a rechargeable 12 volt battery."

Cool.
