Better still, did they mention what ammunition was used? Police typically use +P+ ammunition, especially in smaller calibers like .32 and .380. I have no doubt that the original inventor used standard pressure loads or even sub sonics to decrease the chance of a failure such as this. In the end the gun was a POC anyways, designed to show what could be done.

What I find more disconcerting is the continue emphasis on how the gun is "undetectable". While it is certainly harder to detect because of the small number of metal pieces, you still have the ability to detect bullets!! Or are they so focused on the gun itself that they haven't kept up technology to detect gun powder?

As others have mentioned.. its all about drumming up noise to defend their removal of this information from the Internet.
