This depends on skill really. However, I usually carry one extra, just in case. I make it a point to go to the range minimum once a month and recommend our students to do so (although I tend to go once a week).
At least one, simply because that is the component that is most likely to create a problem operating the gun. The spare gives you the ability to 'fix' most problems and stay in or get back into the fight.
