The 45 ACP and 357 don't seem to be talked about much anymore. Have they been declining or just about these days.
As for the .357 Magnum, it was first touted as the ultimate handgun hunting round, but was dethroned in that by the .44 Magnum. That still left it as king of the police handgun calibers, but when they went to autos it lost its position there too.
