My beater is a Model 21 that I bought pretty cheap a few years ago and had had the triggers painted. I tried to get the gold paint off of them and never could so I just left them alone. Don't know what kind of paint they used but it sure is great. Has never worn of either. If I wanted to paint a gun flat black, I might try the paint that you can buy to paint the fire brick in the back of your fireplace to keep it uniform/all black. Now that paint is hard to get off too. It takes quite a few fires to burn it off. Good luck.
