The worlds most powerful handgun

Answer 1

The worlds most powerful pistol is the Austrian Pfeifer-Zeliska .600 Nitro Express Magnum. It is chambered to fire the British developed .600 caliber rifle bullet originally made by Holland and Holland. This revolver was not originally a full production model but a one off, built especially for a wealthy Swiss gent...Mr. Zeliska.

But if you would like one and I am sure that a few of you 'gunslingers' with a bit of disposable income would, then contact Pfeifer arms, and they will make one for you. Priced at 13,840 Euro's. This equates as $17,316* or £11,722* including Tax ( *at Exchange rate as of 20 November 2008 )

So, if you want to shoot one, better lift a few weights first....
