When a single stack mag isn't a single stack...

So I ordered two brand new single stack Blackhawk CQC mag carriers for my USP Compact .45 and it turns out that my single stack mags aren't really single stack. They are too wide to fit in the carriers. The person that I bought them from will take them back if I pay for shipping myself :evil: Not worth doing it money wise so I'm hosed unless someone has two new double stacks they want to trade :roll:

Guess you learn something new every day. BAH! I still can't believe this is a double stack:

offset double stack like my walther P22. single stack visually but offset stacked to hold 10 rds.

Is there a way to make it a true dbl stack to hold more rounds? It's 8 rounds now.
