Over time, guns wear out, and your Smith & Wesson revolver is no exception. One common thing that finds itself in need of attention is the revolver's rear sight blade. It can become bent or chipped or loose, and that might mean it's time for a replacement. This video guide from MidwayUSA will show you the steps to replacing a factory rear sight blade on your S&W revolver, so you have an accurate and improve sight picture.
It's a pretty simple process to replace your sight blade, and all you need to do is turn the windage screw until the nut breaks, then remove the screw and nut. Tap the blade out of the sight body and insert your new one, followed by the windage screw. Turn it into place and attach the windage nut. Then just move the sight blade to the center and sight in.
