I want to replace my damaged rear sight blade.....Can anyone tell me what is the correct rear sight blade height measurement for a 1994 S&W Performance Center, M66-4, F Comp, .357 Cal., 3 inch barrel revolver is?

IIRC while that barrel is 3" the last .5" is port with the sight mounted behind that - effectively giving it the same sight radius as a 2.5" Model 66. That gun calls for a .146" height sight blade. Buy the kit (includes the windage screw) since you have to break the windage screw to remove the old blade.

Adios,

Pizza Bob
