Revolva - Six Gun

A Six Gun is a revolver that holds six cartridges. The cylinder in a six gun is often called a 'wheel', and the six gun is itself often called a 'wheel gun'. Although a "Six Gun" can refer to any six-chambered revolver, it is typically a reference to the Colt Single Action Army, or its modern look-alikes such as the Ruger Vaquero and Beretta Stampede.

Until the 1970s, when older-design revolvers such as Colt Single Action Armys and Ruger Blackhawks were re-engineered with drop safeties (such as firing pin blocks, hammer blocks, or transfer bars) that prevent the firing pin from contacting the cartridge's primer unless the trigger is pulled, safe carry required the hammer being positioned over an empty chamber, reducing the available cartridges from six to five. This kept the uncocked hammer from resting directly on the primer of a cartridge. If not loaded in this manner, the hammer rests directly on a primer and unintentional firing may occur if the gun is dropped or the hammer is struck.

Six guns are used commonly by Single-Action Shooting enthusiasts in shooting competitions, designed to mimic the gunfights of the Old West, and for general target shooting and personal defense.
