No, The sig will outdo both of them in muzzle energy, but the 7.62x25mm will outdo the 327 in muzzle energy and is slightly faster. Not talking handloads. The revolver is probably more versatile when it comes to that. I'll stay with the tok round.
All that is true unless you want the revolver's form factor. My point was it's hard to compare a revolver caliber to a semiauto caliber, as to many one is not an apt substitute for the other. I apologize if that was not clear.
