During the U.S. military’s search for a breechloading rifle design in the years after the Civil War, America’s first military bolt-action was deemed both novel and sometimes dangerous.
Perhaps the British could claim at least a small amount of credit for the advent of Smith & Wesson’s Model 1917 .45 Auto revolver. Just into World War II they first contracted with the company to buy Hand Ejector, 1st Model revolvers famously known as “triplelocks” converted to fire their .455 Webley cartridge. Besides that third lock securing the cylinder crane to the main frame, those handguns also had a shroud covering the ejector rod on three sides.
