Luger Sight Picture

I just brought a Mauser 42 shooter from Ralph. Of course after picking it up from the gun shop, my next stop was the range. It was then that it truely hit me that I was looking at a different sight picture from my old colt .45. Just what is the proper sight picture for a V notch Luger? Is the tip of the front sight suppose to be just under the desired point of impact a la a M-1911? Or should more of the pyramid cover the target?
