Stand up, out in the open face to face gunfights don't last 32 rounds. If your gun runs dry and you're still alive, it's because the threat has been neutralized or you have moved to cover. You have plenty of time for a magazine change there.
6+1 x 9mm in my Kahr PM9 + an extra mag is good.
7+1 x 45acp in my Colt Defender + an extra mag is very good.
18+1 x 9mm in a Glock + an extra mag is awesome
