Corrected entry: We know from the first movie that the small "cricket gun" is very strong because Will Smith flew backwards and the gun made a huge hole in a big truck. However, in the second movie, when Tommy Lee Jones uses the gun to blow off Jeebs' head, it sounds and acts like a regular plasma sort gun, that only fires a plasma or laser beam.

Correction: The reason that the noisy cricket blasted J back in the first movie but not K in the second movie is because that gun can be "dialed up" in power. According to the website for the first movie, rookie agents were often given noisy crickets dialed up to full blast by their superiors to teach them a lesson in perception.
