Uh, no. Airsoft guns fire pellets that are in the neighborhood of 3 grams. The type of gas pistol used in the video is a self-defense item intended to be non-lethal, and the more popular models fire rubber bullets that are about 11.5 grams. At close range, they can cause lethal injuries.
Calling it an airsoft gun is like calling a stick of dynamite an M-80.
