McCormick is the best value I feel. But I have more Wilson mags than McCormick. I think of them as an investment since I will always have a 1911 around.

Something to consider. Whatever you buy, buy one and see how it works in your gun. 1911 magazines will differ slightly.

Wilson magazines in my DW Bobtail will not lock back after the last round but McCormick mags do. And one of my Kimber won't feed reliably with McCormick.
