The .357 Sig was originally designed for one purpose in mind -- to give police who were still holding on to their .357 Magnum revolvers a semi-auto cartridge that would emulate the performance of one round -- Remington's 125-gr. semi-jacketed hollow point, which at that time had a well proven track record as an excellent fight stopper.
It wasn't designed for versatility, or for sporting purposes. It was conceived of and promoted as a police and defensive cartridge.
