This is completely correct. However, there's more to the idea that is significant to know. The attempt was to duplicate this performance in the typical auto carried by LEO; for example, standard size and compact size Glocks. Of course, the idea was to give cops the best stopping power (statisically speaking) while also providing the advantages of the auto; large capacity and quick reloads.

That is the light under which comparisons should be made. To compare 357SIG performance to what .357Mag is ultimately capable of, is simply invalid, as that was not its purpose.

That having been said, the ballistics of the 357SIG are exactly the same as the ballistics of the ammo/revolver combo it was meant to replace. Suffice to say that you would not be at any disadvantage by replacing your typical carry .357Mag revolver with a 357SIG auto.
