The K-19 is a lethal electrolaser, able to produce a powerful enough shock to kill a living target and severely damage electronics.
An electrolaser uses a laser to ionize the air, creating a LIPC, laser induced plasma channel, which acts as a conduit for electricity, killing the target with a powerful shock. Artist's Note: I redesigned the K-19, as I felt that the original design was too bulky, dull, and ugly.
...I can't believe I put J-19 instead of K-19 though...
However, this is still a sexy gun.
