What's the advantage of Ruger Mark III's fluted barrel?

LGS salesman showed me another variation. It's grip is more like 1911, and the model name is indeed 22/45 I prefer Luger's grip angle, so I bought this one.

Which one??? That looks like the bull barrel...

You decided against the flutes? I was curious as to how they looked...A member here once asked if a target barrel could be fluted...But it seems as if slabbed barrel is more popular...
