I'd rather have a 9mm but the only reason I'm considering the .45 P220 is its thin single stack magazine. I'd like to know if there are factory P229 10 round magazines that are also thin single stacks like the P220's. I live in California (yes, I know, I hate it too) so I'd like to be able to fit two thin 10-round magazines in my vest's magazine pouch vs. one big-fat-useless-limp version of a 10 round magazine. Thank you!
