lawgiver
A fictional futuristic looking handgun from the Judge Dredd stories in the 2000 AD comics anthology and the 2012 Dredd film.
The Lawgiver is the standard street judge personal weapon. It responds to voice commands thanks to its built-in advanced microcomputer and can also fire several different types of ammunition, which include sound-suppresed bullets, standard bullets, armor piercing bullets, incendiary bullets, full-auto, semi-auto and single-action bullets, 2-shot arc "Double Wavy" bullets, high explosive rounds and electric discharge stunning rounds.
The Lawgiver also has an advanced "DNA check" user verification system that only allows the owner of the gun to fire it.
