I saw you missed out on a Mitchell Right Side Mag Release. I have one for a 1911 and one for a 2011 that I'm no longer using if you want to buy one of them for the same price. Let me know.
They are not altered. They both worked as drop in parts for my guns. I would ship both of them to you for $160, or $80 each. I'll send you pictures later tonight, assuming I don't forget. I'm in the office now.
