Customizing an Interarms Firestar M-40
I just bought an Interarms Star Firestar M-40 in .40 cal a week ago from a friend. It's in good shape, but I want to polish the trigger, hammer, barrel, guide rod, safety, slide stop, magazine floorplate and the grip screws. The barrel and guide rod look like they're blued, but the rest look like they're parkerized or something. They're kind of a dark gray color. I already know distilled white vinegar will take the blue off. But what about the other small parts?
Also, I plan to strip the blue on the frame and slide and parkerize them. I'm not much of a fan of bluing. I just want a nice matte black finish on them. Would parkerizing achieve this? Or would I just have to duracoat them? And would I have to strip before duracoating? Or maybe just strip, parkerize and then duracoat? I saw someone on youtube saying he swears by parkerizing and then using duracoat for double protection.
Any help would be appreciated.
