The 10mm Auto

The 10mm Auto arrived in 1983 with the Bren Ten pistol, and the FBI adopted it in 1989. Its full-power loads proved a handful, which led directly to the shorter .40 S&W a year later. The 10mm case was also necked down to create the .357 SIG.

Related pistol rounds: .357 SIG – made from the 10mm case – plus the .45 ACP and 9mm.
