Taser

Tazers, also known as stun guns are non-lethal weapons built and used by the Tau'ri. Those weapons seem comparible to Zat'nik'tels and Wraith stunners.

The weapons were used by the Atlantis Expedition during their first year of operation, to capture a Wraith for intel on their plans. It is proven that enough Tazers has the ability to stun a Wraith, but would still not knock them out enough for them to initiate a Self-destruct. A year later, Lieutenant Colonel John Sheppard used the tazer to subdue Steven Caldwell's Goa'uld long enough for him to give Sheppard the abort code for the self destruct.
