I have a few used 20 round magazines with the original alloy followers. All show finish wear, but one is starting to develop a relatively small divot where the edge of the last round is stripped off of it. Since this follower is down to the bare alloy I was wondering if I should refinish it. Anodizing would be nice, but since I'd rather not have it wear away the inside of the mag I was thinking of getting it plated and just doing the rest of them at the same time. I am considering nickel or chrome, and possibly having them bead blasted on the top to produce a matte finish on the area that would show with the bolt locked back on an empty mag. There is a place that does chrome plating near my parents' home and I am going to see if they would do it cheap. Do alloys need to be nickeled before chroming? I know there are different grades or types of aluminum so does anyone know which one I am dealing with? Also, is the original finish on the Colt alloy followers anodizing or something else?
