Just took delivery on my Ruger Alaskan. The front site is a black finished blade. My eyes have a difficult time picking it up, so I am considering changing it out for a fiberoptic site. In reviewing the procedure on youtube it seems that I must drill a hole in the site blade to align with the hole in the frame, and drive a roll pin in to secure it. Is it possible to instead secure it with crazy glue? I realize it would become non removable, just thinking outside the box. I am unsure how I would mark the site blade for proper alignment of the hole.
