My .45 only has a ten round mag while my 9 mm is 16 so I usually carry it. Both CZs. My first real pistol was a Browning ‘Hi-power’ so I got used to and like that grip.
I’ve never read here of a gang of ferals larger than 15. Yep, be prepared. I’ll be happy if I never have to draw again but have had to a couple times.
My 45 is a full sized 1911, so 8+1. My 9mm holds 15+1. I always have spare mags, whichever one I’m carrying. On a recent trip with my wife I brought a carry and a spare carry piece for her (both have our CC permits). Even after 20+ years of marriage communications can break down. She brought a carry and a spare for me. We ended up on our romantic weekend getaway with 4 firearms and 100+ rounds. ;-) I love that woman.
