Fastest hand held gun

Answer 1

You will have to define what you mean by fastest. Do you mean the fastest velocity of a bullet in flight, or how quickly it can fire a second or thrid shot? For the fastest velocity, probably a handgun such as the T/C Contender, firing a rifle type cartridge. For rapid fire, there are several machine pistols (fully automatic) that fire several hundred shots each minute. Of course, thre is the mini-gun used by Jesse Ventura in the movie Predator- it fires several THOUSAND shots per minute. But you won't find those at your local gun shop.
