As long as the wedge draws everything up tight without binding the cylinder you are OK but I can understand your not liking it sticking out so far. I have a number of Piettas in which the lug goes through enough that the spring latches on the frame or almost does and an equal number in which the wedge only comes flush with the right side. If it bothers you take a file and carefully remove metal from one face of the wedge or the other till it goes in (not much) further. Touch it up with some cold blue and it won't affect the function at all. I have two Pietta 60 Armys, consecutive serial numbers, on one the wedge is flush on the right and the other it's far enough through the spring is on the verge of snapping over the edge of the lug. All the parts have a manufacturing tolerance, a maximum and minimum size, and when they start assembling guns a maximum wedge in a minimum slot just won't go in as far and it doesn't take much.
