Dont know if it helps but i have a 51/2" stainless model with fixed sights and had to remove a couple of mm from the front sight to get it point of aim at 25 yds. Normal load is 18 gns of swiss pistol with 2 scoops of semolina and a .457 ball with wonderlube over the top.
35 grns is a lot of powder! Let us know how you get on.
