Glad it worked for you, the low spring tension of the bolt legs is a common cause of early bolt drop and timing problems, especially in Italian clones where the steel and heat treat aren't up to snuff. You might not need a front sight as long as you can hit what you want point shooting, depends on your grip and ability to shoot without sights. Often, with a percussion Colt, point shooting is closer to target than the sights, which shoot high. I replaced the front sights on two 1860's and the new sights, when filed and adjusted to target are 5/16 inch tall.
