The Klingon disruptor started life as an Eminiar Sonic Disruptor in Episode 23, “A Taste of Armageddon.” Later, with the introduction of the Klingons in Episode 26, “Errand of Mercy,” there was a need for a new hand weapon, and as the producers had no plans to return to Eminiar VII, they had the propmakers redress the sonic weapons with new tips and a housing on top with a scope. And so the Klingon disruptor was born.
