I'm test driving a lightly used Stock II. It came with 4 mags, one blued and three shiny. Chrome, I assume. The blued mag drops free empty, always. The shiny dudes, however, do not. Only obvious wear marks on mags is on forward top of mag right below where bullet tip would be if loaded. Mags are marked 9mm and a T in a triangle if that helps. Followers are red. Also, how much better can I expect the trigger to get if I diddle with springs and put the KneelingAtlas hoodoo on it? Thank you, resident geniuses.
