As seen in the TV series Star Trek: Discovery, this costume accessory was created using reference taken from the original screen-used production assets, and produced in the exacting manner that the screen-used pieces were for production.
The phaser features “Stun” and “Kill” settings that can be selected by a side switch on both the left and right side, with lit “ring” indicator light at top. (“Stun” is blue; “Kill” is red.) It also features a removable “P1” / cricket phaser from top, with a spring-loaded pop-up scope, and a rotating barrel.
A removable magnetic battery “clip” with lit indicator light goes into pistol handle, just like the original asset. The phaser also uses replaceable consumer batteries which means that there’s no need to worry about shelf-life for unserviceable, custom-made rechargeable batteries.
