Fiber Optic rod diameter

[TOMC]

I have a 5" Pro and the front sight F/O rod broke. I called S&W...he had no clue and gave me Hi-Vis phone #...no answer. I called Brownell's and they said they did not know specific diameters, and suggested I try to insert a small drill rod to find diameter...good idea but I don't have one that small.
Does ANYONE know what diameter F/O rod I need, .20 .30 etc.
Thanks!
