I just put this information into another guy's thread and thought it would be useful to some other folks. So here it is:
I have a Pietta 1860 that I replaced the front sight on. It is not tough to do, and kind of fun. The sight is pressed into a half-moon shaped slot in the barrel. Kind of like a key slot on an electric motor shaft. Take a brass punch and drift it out, back to front. If you can't get enough purchase on it, put several layers of tape on your barrel and use a cold chisel on the sight. Then get a scrap piece of brass (I got mine from the hardware store) and cut a piece off it that is longer and wider than the sight slot. You might want to leave it long to give your vise or bench clamp something to grip. Carefully reduce the thickness until you can just start a corner into the slot with tight interference. Then shape it so that it is just as long as the slot, and round the bottom edge until it pretty much matches the bottom of the slot. Cut the blank off so that it is a little taller than what you think you need it to be, with the top being square to the barrel. Set the blank on the slot and hammer it straight down until it won't go any farther. You can round off the top now with a file. You will have to test fire and adjust height until you have the height you want. Also, the new sight will be too wide and probably need to be adjusted for windage. Put tape on your barrel to protect it while you file the sight to the width you at the top. The sides will be sloped from bottom to top. While doing this, test fire to see which side will need more material removed for your windage adjustment. Don't try to knock the top of the sight to adjust it. I used a jeweler's file to square off the rear sight notch before making the final tweaks on the front sight. Good luck.
