Call S&W, they are available and very inexpensive. Any time you change a blade it is very easy to lose a ear sight detente pin and plunger, While you are ordering one, best get two. Then, whenever removing the blade and you have to screw the windage all the way out, do it inside a large clear plastic bag.
