Kzinti phaser
The Kzinti phaser was a hand-held weapon used by the Kzinti during the 23rd century. It had a stun setting, which temporarily knocked its victim to the ground. 

The crew of the Traitor's Claw used these weapons against Hikaru Sulu, Spock, and Nyota Uhura on a planet in the Beta Lyrae system, although the Kzinti were prohibited from possessing such weapons by the Treaty of Sirius. ()
