It's not the accuracy that is your problem, it's the point of impact. They are amazingly accurate, once you get the front sight lifted. A Colt Navy type needs from 1/4 to 5/16 tall front sight to get on target, and a dovetailed blade type is the best way. I have done it two ways, I used an Uberti 58 Remington dovetailed blade purchased from VTIgunparts.com, which is too tall, but cut down to about 1/4 inch tall with a straight back and radiused front looks good and shoots well. I have also made them from scratch from brass using a Brownells dovetail cutter for the slot and the sight base both for a perfect match. They could also be made from mild steel.
