The zat gun is recalled as stunning with one shot, killing with a second and disintegrating its target with a third. Later scenes allow a victim to survive two shots, challenging that rule. Ancient technology can supply an explanation within the story without explaining the physical mechanism. The criticism therefore concerns both internal consistency and the distance between the fictional effects and known physics.

The zat gun's stun, kill and disintegration sequence is used to question claims of consistent Stargate physics.
