This is how I modified the front on my Pietta 1862 snubby in order to have it shoot to point of aim. First I removed the sight from it's dovetail and clamped it in a vise. Next I cut off one of the sight blade supports and removed the blade. I then filed the remaining blade support into a triangular shape, shortened the sight base, sanded and blued the new sight, and remounted it in the barrel. Hopefully this will raise the point of impact to about the right spot!
