Great magazine - Chip McCormick Power Mag .45 ACP

I purchased this magazine for my Springfield Range Officer. Fits in perfectly. Magazine has the base extension with the letters "Chip Mccormick Custom LLC Power 10". It does not look like the picture. It inserts nice and snug with a click to indicate full insertion. Once out of the box it took a few inserts to get broken in. With the magazine inserted this still fits in the center console of my 2014 Ford Fusion. This my first one, I plan on buying more. Its is black with a black base. Round go in smooth. No failure to feed.
