In reference to guns do you call it a clip or mag?

Also if you're in the US are you from the North or South. From who I've talked to it seems Northerners typically say clip and Southerners mag. Reposting this cause I couldn't edit the post from a bit ago.

Edit: I know I should have added an option for non-US people, but I can't edit the poll and I'm not doing this a third time.
