I dunno what you carry. Some want 18+1 and 3 spare mags. Some carry a 5 round j-frame and feel fine. Its up to you.
This is why I always carry at least one extra in my pocket. It may malfunction. You may hit the mag release accidentally and it ends up under a car or down through a grate. I think carrying an extra to get you back in the game is cheap insurance.It's not just about have ammunition. The magazine are wear parts and can fail. It's about keeping your pistol operational. Plus, the only time you can have too much ammo is when you are trying to swim.

It is surprisingly easy to accidentally press the mag release on some guns under stress. You may never know it when you're taking your time with marksmanship practice with a perfect grip. Add a timer, movement, multiple targets, reloads, etc. and things get a little more complicated and that perfect grip can stray a little.
Downside to carrying an extra mag is weight and loss of space on your person.
Downside to not carrying one could possibility mean your life or a loved ones life.
I have got into the habbit of carrying one. Not for the fact that I'll need the ammo (if I know I'm headed into a gunfight, I'm taking my rifle. And that's only IF I go. Best way to win a gunfight is not to be there.) I'm more worried about a malfunction than running out of ammo.
My 2 EDC's are a 9+1 and a 19+1.
