Hold on cowboy. Thoes extra mags are great if you were to ever also own the XDsc. Just buy extra, or slip the existing sleeve of the sc over the longer mags., and then they work for both pistols. This was a goldmine for me when I got my sc, and rangetime comes around.. i was thinking that i could sell the extra mags and holder and get some of my money back. i only need 3 mags.
