I have used a toothpick to put a white dot on traditional T/C front sights. Dip the toothpick in white paint, and apply to the front bead by tapping a round white bead. This actually works quite well. I have also used T/C fiber optic sights to replce the factory originals. I do not recomend the older style T/C fiber optics. The top of the rear sight moves, and it is just a cheap set-up. Williams Sight Co. makes the fiber optic sights for the newer T/C MZ's, and these are much improved. They also can be had, to replace factory originals.
