Phaser - Star Trek: The Motion Picture (1979) Has multiple settings (Stun, Thermal Effects, Disruption Effects)
Can easily reverse polarity of the beams, for several different effects.
Lots of power, but fits in your pocket.
Lawgiver - Judge Dredd (1995) Fires standard bullets, grenades, signal flares, and of course, everything at once.
Can only be operated by the palm print of the gun's owner.
Nothing else quite says, "I am the law."
