Want to change the front sight on a S&W 686-6

[nonferrous]

I would like to change the front sight on my 686 to a hi viz. The sight blade has a pin holding it, but I am sure that it's not as easy as it looks. Before I start, can anyone give me a heads up as to what is involved?
Thanks

I am interested also, The BIL want's to try a Williams fire sight, since they work so well on the other revolvers.

you knock the pin out.
You take the replacement site, clamp it very tightly in the slot.
Drill a hole thru it and then repin it.
You want the site to sit as tight as possible

Thanks,
It's a .060 roll pin and I have the punch, thanks for the instructions, they removed the guesswork and give a little confidence.
Thanks again, Len

The new site doesn't have a hole in it.
You only drill it when it is clamped in the pistol
