Created by artist Paul Erard in the Swiss city of La Chaux-de-Fonds, the petite pistol measures just two inches long but fires with one joule of power.

The gun currently holds the Guinness World Record for the smallest working revolver, and the bullets it fires – which were designed specifically for the gun by Mr Erard – also appears in the book as the tiniest live ammunition ever created.

Small but mighty: Created by artist Paul Erard in the Swiss city of La Chaux-de-Fonds, the petite pistol (pictured left alongside a full-size revolver) measures just two inches long but fires with one joule of power

Looking like something fit for James Bond, the petite pistol measures only two inches long. With a height of just 1.3 inches and only 0.3 inches wide, the gun could easily be hidden up 007's sleeve.

The mini-revolver can be made to order in solid gold – with each one costing a staggering £300,000 to manufacturer, although former watch-maker Mr Erard is selling them for just £4,500 a piece.
