I just purchased a 686-3 8 3/4 inch Revolver in the Target Champion configuration with four position front sight. Manufactured August, 1990, "BFF" prefix s/n.
I'd like to get a PDF scan of the Smith and Wesson manual that describes adjusting this sight. The more modern manual is available on the S&W site, but it doesn't cover this front sight.
Does anyone have a copy of this manual to share?
