There is a 180gr offering though it is from Double Tap.
The .357mag has more case volume so it is always going to be better suited to pushing heavier bullets faster. Due to that capacity, longer barrels are also preferred to help burn all that powder and increase velocities. For every day carry I just prefer the .357sig, my dad prefers his 7 shot .357mag revolver. For woods carry I would just as soon step up to a .44mag Redhawk.
