Guinan with a weapon from Magus III

The Magus III energy weapon was a type of energy-beam rifle.

In 2367, when REM sleep-deprived crewmembers aboard the USS Enterprise-D began to draft conspiracy theories about their inability to escape the Tyken's Rift in Ten Forward, Guinan grabbed the weapon from under the counter, set the setting on the weapon to one, and fired the rifle into the ceiling above the mob, which defused the situation. Guinan informed them she had acquired the rifle on Magus III and asked if anyone wanted to see setting two. (TNG: "Night Terrors")

In the script, the weapon was described as a 24th century version of a shotgun. [1] It was also seen in the Buck Rodgers episode "The Hand of Goral" [2]
