Mobile Phone Gun

This is mobile (cell phone) that appears to be like any ordinary phone from the outside but is in fact also a .22 calibre gun. Its a properly working phone that can be used to make and receive calls and not one of those gimmicky phones merely designed to hide its main purpose - the gun. I would assume that in this case the main purpose is probably the phone, or both in equal measure.
Inside the phone there are 4 barrels and pins with bullets. The gun is able to fire these shots in quick succession as the video below demonstrates. The keypad on the phone works as trigger for firing. I must say it was quite discomforting watching that even if it was only a demonstration.
I would assume a product like this would be banned in the UK and much of Europe, however, it may be available to be bought in the US and other countries freely where gun ownership is much more readily accessible, although I am not totally sure.
