What is the fastest handgun?
Fastest in what way? Bullet that travels fastest? That would be
a pistol chambered for a very fast rifle cartridge, such as the
22-250, .204 Ruger, or .220 Swift. Fastest firing? Pistol version
of the American 180 submachine gun- it fires .22 long rifle ammo at
rates of nearly 3000 shots per minute.
