I know. 10 round mags are better than having no extra mags. I bought several inexpensive 10 round mags from ebay that I initially used as range mags. Then I temporarily moved to New Jersey and my range mags became my regular mags. Go figure. 10 round back up mags are ok for me, especially in this time when things can be hard to find.Ebay doesn't allow mag sales over 10 rounds.
