No.
FO rods are fragile when not taken care of, like any other part of your firearm.Personally, I'd never consider TFO's, or any FO on a fighting handgun--far too fragile.
Gold beads can't puke a tube, or have their tritium vial rupture or have a half-life...gold doesn't tarnish, and has a high albedo so will reflect light in dim conditions.
That being said...I do run tritium (mainly Trijicon) on most of my social handguns.
