Revolver Cal.45 Peacemaker 5½”, S. Colt, USA 1873.
This weapon was initially used by the US Army. However, within a few years, most of the American citizens got one of these revolvers. The fact that it used ammunition of the same caliber as the Winchester M1873 rifle helped its popularization as a short weapon in the old North American West in the late nineteenth century.
Curiously, this revolver has received numerous nicknames. Apart of the mentioned Peacemaker, also it was known as Frontier or Widowmaker, in reference to the facility of this revolver to left widows among the wives of the time.
The film industry mythified the “Peacemaker” in the westerns of the 40s and 50s, and it was associated with big screen stars like John Wayne or Gary Cooper. Also Roosevelt had one with his initials engraved and George S. Patton used two.
