I made a bunch of guns with tall sights, and frankly, I like this style at the range, when the barrel eats up and mirage plays with the number of sights you see. Or is that old age?
I have tended for more traditional height sights lately, because I have become more traditional as get into the historical aspects of the American 18th Century gun. My sights are still taller than most originals, running about 1/8 tall, a sort of compromise height.
Most early sights I have seen are VERY low. In general, these guns were not made as fine target guns, but tools to bring dinner home with. Or pick the enemy off at 200 yards.
