Introducing the world's smallest gun that fires deadly 300mph bullets - but is just TWO inches long

This is the world's smallest gun - and although it might look like a harmless toy to some it is anything but as it is capable at firing deadly bullets at a speed of 300mph.

The Swiss Minigun, being marketed as a collector's item, is two inches long, and fires 4.53mm bullets.

Costing £3,000 in stainless steel, a gold-plated, diamond-studded version is also available.

It cannot be imported into the UK, and buyers in Switzerland and Europe must get a permit from police to own one.

The gun is banned in the US - because it is too small to qualify for sporting purposes.
