NH, I have done the "salt & pepper" thing on 1911's, Ruger MKII's and even a S&W 469.
The results are even more dramatic when the SS parts are brought to a high polish, depending on what effect you are trying to achieve.
As stated above, most parts are drop in, but if you find one that is troublesome, you can always reinstall the original pieces until you figure out the course of action.
The rear sight is easy, it just "knocks out".
The front sight is "staked" in and is best not messed with, as far as ripping it out.
But, you can dot it yourself...I use a hammerless punch, putting it where needed, leaving a indentation, then follow with a drill, sized depending on how large you want the dot to be.
Then either a mixture of epoxy and white enamel or just white (model car) enamel, fill in the hole with a toothpick.
I like my front dot "painted" flush so I can wipe my finger over it to clean it while shooting.
Most factory jobs are concave, holding in debris.
Good luck on your project.
