From Terminator Wiki
The Westinghouse M-27 Phased Plasma Battle Rifle is a sidearm used by Skynet forces in the Future War. It has a bullpup configuration and utilizes plasma technology in the 40 watt range. It is possible that the underslung barrel is a form of laser used to ionize a channel through the atmosphere to the target making transmission of the plasma bolt easier.
