I did this several years ago. Wow--what a mess. It seems easy until you try it, but rest assured it's not.
I had a smith who specialized in refinishing remove the chrome. It took several closely-monitored acid baths to do this. Not enough and you leave chrome which will not take the park or bluing. Too much and it eats into the metal. And the markings tend to get fainter and go away even if the job's done with meticulous care.
Second problem is that many chromed guns had metal removed from the rails to allow the gun to function with the chrome on them. When you remove the chrome, you now have a very loose-fitting gun.
And of course even though you're absolutely sure that you got every last bit of chrome off, you'll never really know until you try to apply the new finish and it doesn't take in certain areas, typically the slide serrations or areas where there was deep lettering.
It's a project all right. Do it slow and right and you'll have a pistol to be proud of, but it's aggravating and time consuming. I would not try it again personally, but everyone's entitled to one try at it, I guess. Good luck.
