Bugs, If you're wanting to do it yourself, I'll describe how I have done it. I first detail strip the slide, and the frame too, if I'm going to be refinishing that. I mean totally detail strip, everything. Then, I either do a fine bead blast using Brownells 270+ or Harbor Freight #80 glass beads at 60 psi or so. If you decide to do the alloy frame too, you'll have to be VERY careful. You just want to gently blast the anodized alloy frame with low pressure and holding the blast gun further away than with the slide. Almost just a cleaning using the glass beads. If an alloy frame just has a clear coat,I would not use this process at all. In that case I'd recommend back to the manufacturer, or one of the painted on type gun finishes. After blasting, clean with solvent,air pressure, Q-tips,etc. The tiny glass beads will get into ever crack and crevice. Then clean, and clean again, before reassembling.....ymmv
