I can see the barrel line up with the top of the blade, but sadly, if you were to make a straight line from the top chamber of the revolver to the "barrel" of the gun, you would see that it doesnt line up with the point that you claim to be the end of the barrel, and actually would shoot back into the tip of the sword where it comes to a point. I prefer the energy idea, as I can't imagine a gun barrel being curved, and the side barrels and other ideas like them have been disproved by pictures. Also, consider the flexibility of steel used to make swords and bladed weapons, then remember what would happen to the perfectly round barrel of a gun that is constantly being used as a sword. Although to be honest, the scars that are traded at the beginning of the game if given by real blades, would have a Squall without a maxilla (his upper jaw), and Seifer would have a broken orbital bone (above his eye) because the weapons would be so heavy that they would shatter, not cut, bone. Oh well, its Magic I guess
