I totally agree the front sight is better. I think the fiber optic looks awful - just my opinion. I did put one on my Ruger MKII target however and it works great.
Here's my 63 with an Altamont grip. It has the red fiber sight, I prefer black Patridge sights on all my revolvers but I don't really use this revolver much. Allchin makes a dot mount for it and I thought it might be fun to put on a reflex sight.
