Need some assistance from my fellow at 1911 shooters.

Just looked at mine, if it's anything more than paint I can't tell it.

I'd use model paint and a toothpick.

I have used the toothpick and model paint before and it does the job well. After a few years the paint wore off again and I used some glow in dark model paint to give me cheap night sights. It has held up well and I'm able to do touch ups when needed. Toothpick will be your best tool to apply or reapply.

Another vote for Glow in the Dark paint.

I've redone the sights on my yugo SKS and my glock with glow paint. The kit comes with two little tubes, one a white primer and the other the glow paint. as the others have said a toothpick is the proper way to apply

works great and now you have night sights
the kit is cheap and you have plenty to do many sights

I think i got it at academy, or basspro
if the dot on your sights is paint you can dig it out, if it's not paint just put the primer right over your dot, let dry, then a couple drops of the paint letting dry between drops. The primer is thicker so easier to apply but the glow paint is pretty thin, just dip the toothpick in the bottle then gently tap a small drop on to the white area
