Randy, there is a specific Mec-gar Magazine for the ATI Titan which is (ATIMG1911457) - ATI sells them for the Titan here : americantactical.us/5850/detail.html --- I would call ATI to verify before purchase at 800-290-0065
"Blue" is a coating process where a chemical is used to cause a protective coating to form on metal. depending on the polishing and actual chemicals used the "blue" can vary from a high gloss black to a dull matte black low gloss finish this is the matte black low gloss finish
Randy I would recommend Wilson Combat Officer Mags. Now mind you, you will need a file or dremel to shave a small amount from the front of the base plate on both sides for a perfect fit in your Titan. The original magazines are unfortunately very hard to find and a few minutes of your time will give you reliable mags for your Titan. Details here : youtube.com/watch?v=rNVnpaty_cA
