Mk 1 phase pistol

The Mk 1 phase pistol was a hand held energy weapon used by United Earth Starfleet and the Federation Starfleet from 2151 to 2259, at which point it was superseded by the Type-2 phaser pistol. Despite its replacement by Starfleet, it continued to see use in the civilian sector as a personal defense weapon, though a number of restrictions on the ownership of these weapons were enforced on many worlds.
