I have a Pietta 1851 Colt Navy .36 cal. I have been tuning this for reliability and finally have many issues corrected. The final one is that I noticed that the front sight is canted about 5 degrees to the right. I always wondered why it shot to the left when rested. I think that I want to have a sight dovetailed in so I can drift it for my eyes and zero it in at 15 yards. Any of you had the front sight dovetailed in?
