first of all what kind of gun do you have? if its an automag you can only get it powdercoated unless its got a ule body on it. If its got a ule body or its an electro gun or something like a spyder you can get it annodized. Please don't just paint it, you will not end up being happy when it starts to flake and makes your gun look ugly. Either of the processes I mentioned are pretty expensive and aren't worth it unless you plan on keeping hte gun for a while since you have to send teh parts you want colored away to a company and then be without them for 4-6 weeks usually. If after this you still want to then A+ Annodizing in the states is an awesome company from what I've heard and have done some wicked things.
