The concept of a revolver chambered for 45 ACP goes back to WWI, when Colt and Smith & Wesson brought out their Model 1917s to fire the semiautomatic-pistol cartridge through the use of half-moon clips. With the more recent introduction of full-moon clips, these six-shot revolvers can be reloaded very quickly as long as you have a supply of loaded clips. The original S&W Model 1917 had a detent to hold the cylinder fully open, which helped expedite the reloading process. Recently, revolver maestro Jerry Miculek proved just how fast a 45 revolver can be reloaded. He fired six shots from his gun, dumped the empties, reloaded, and fired six more—all in less than three seconds.
