Introduced by Colt as an improved version of the older .38 Auto, the Super Auto is identical to the original cartridge except that it uses a more powerful loading. For many years this cartridge was considered the most powerful automatic pistol cartridge made in the US from the standpoint of both velocity and energy. It can give greater penetration than the .45 Auto cartridge, bit is inferior to the .45 Auto in actual stopping power for defense use.
