I have long time ago for my personal use found original lugers with 4" barrels to light and I needs more weigth.
I have made a dramatic change in my competition results with adding the heavy oktagon barrel.
I am pretty sure that most people finds the same with the navy as its better balanced and they get better results with it.
But the results is due to the balance and not the sightradius.
