SHOOTALL, I have carried at one time or the other, the Para P-13 in 45acp, the Commanders, the Lightweight Commanders, the full size 1911s and so on, and one of the best was the Glock 23 in 40s&w, and liked them all for what they were. The nines were very short lived in my carry stable although I spent 10 years training officers to fight with them, I could not in clear conscious carry one myself. On one occasion AFTER an actual fight in 1978 where a car was used for cover, I left the 1911 behind and immediately went back to the 357 magnum.
After leaving L.E. after 20 years I went back and forth between the 45acp and the 357mag, and finally settled on the 357mag most likely permanently. If after 5 to 7 rounds I am still fighting, what I'm doing isn't working, and I need to think about leaving. Even in the 1978 incident I only fired 5 rounds and it was over. In my present environment, all fighting will be purely defensive, unless a family member is threatened, and then the perp will find hell coming out of no where.
Round capacity looks good on TV with running gun battles and such, but my experience, and the experience of friends, it's over as fast as it starts. I'll take the power over the quantity. If your happy with lots of 9mm, or 45acp then by all means carry it.
