The Peacemaker
I was half watching a program on the History Channel today about the evolution of the revolver. They covered the history from before the period of European Pepperboxes to the latest revolvers.
Of all the antique revolvers shown on the documentary, my favorite was Sam Colt’s venerable Single Action Army revolver. The show mentioned the caliber of the gun as simply being “.45 caliber.” I seem to recall that these guns fired a .45 Long Colt, not to be confused with the .45ACP ammunition for semi-automatic pistols. According to GunWiki, .45 ACP ammunition is regulated to under 21,000 lbf/in² (145 MPa), while .45 Colt must be kept under 14,000 lbf/in² (97 MPa) to be safe in older guns.
Technical details notwithstanding, the Peacemaker sure is a pretty piece of Firearms Americana. Clickable image.
