Handgun hunting is a form of hunting primarily done with specialized handguns that have long barrels and mounted scopes (optical aiming devices). Even the largest animals, such as elephants, can be killed with modern hunting handguns, although most handgun hunters only use handguns when hunting medium-sized game like deer and wild hogs. Most hunting handguns are either single-shot pistols, single-action revolvers, or double-action revolvers.
