What is Revolver?
{{otheruses}} [[Image:Anaconda-502.jpg|thumb|upright|{{center|.44 Magnum revolver}}|alt=]] A '''revolver''' is a type of gun. Revolvers are repeating [[firearm]]s with a [[Cylinder (firearms)|cylinder]] that spins. Revolvers have several [[:wikt:chamber|chambers]] each holding one [[Cartridge (firearms)|cartridge]]. Most are handguns, but other types of weapons also use revolving cylinders. They are also called '''revolving guns''', though ''revolver'' is used far more often. The first revolvers date back to late [[1500s]] in [[Europe]]. It was not until the 1700s or 1800s, however, they became affordable.<ref>{{cite web|title=S&W history|publisher=Smith and Wesson|url=http://www.smith-wesson.com/webapp/wcs/stores/servlet/Category4_750001_750051_757941_-1_757938_757812_image|accessdate=February 7, 2014}}</ref> Revolvers are sometimes used by [[law enforcement]] agencies. On some occasions, these guns can be reset by one hand, then loaded with the other.<ref>{{cite web|title=Revolvers' Actions and Tips for Lefties|publisher=The Gun Week|url=http://www.gunweek.com/2000/lefties.html|accessdate=February 7, 2014|archive-date=September 16, 2007|archive-url=https://web.archive.org/web/20070916000826/http://www.gunweek.com/2000/lefties.html|url-status=dead}}</ref> == Action == === Single-action === [[File:Single Action Evolution..jpg|thumb|right|From Top: Replica of 1849 vintage. .44 Colt Revolving Holster Pistol (Dragoon); Colt Single Action Army Model 1873; Ruger (New Model) Super Blackhawk- Mid and late 20th Century.]] In a single-action revolver, the hammer is manually [[wikt:cock|cock]]ed. This is usually done with the [[thumb]]. This action turns the [[cylinder (firearms)|cylinder]] to the next [[cartridge (firearms)|cartridge]]. It also locks the cylinder in place with the [[chamber (firearms)|chamber]] aligned with the [[barrel (weapons)|barrel]]. The [[trigger (firearms)|trigger]], when pulled, releases the hammer, which fires the round in the chamber. To fire again, the hammer must be manually cocked again. Th
