To my understanding: The .357 Sig doesn't have quite the power of a .357 magnum...but it's penetration performance matches that of a LIGHT .357 magnum load (125 grain). Beyond that, the .357 Magnum comes out well on top especially with heavier loads like the 158 and 180 gr.

Some have said, I won't swear to this, that the 10mm semi auto has energy equal to that of the .357 magnum...but someone else smarter than me can comment ont his
