Go to duracoats website and order there or from brownells. I would strip it down to the frame and spray everything but the internals, frame, trigger, hammer and all just not inside the frame or barrel for obvious fit and function (safety) reasons. Its pretty cheap if you do it yourself and is a very tough finish and will last a very very long time. Also, you dont hae to bake your parts when your done it cures on its own and dont worry if you dont have a compressor they have kits that include their own propellant just have a nice long look at their site, they have a sh*t ton of colors to choose from have fun.
