I think the gun in your link w/ the two 13 round mags is still a "compact" model w/ the shorter grip. If you still have worries, you could always call the seller or send an email to confirm.
Good luck and keep us up to date
Thanks to everyone.
This is exactly what I hope it means. I already own two 9 round clips for this gun. If they send me 2 13 round clips with mag extension, that would be perfect.
I'll have 2 9 rounds, and 2 13 rounds.
If it would be the long hand grip, then my 9 round clips would have been useless.
Ill call them and update thread for those interested.
