Situation determines what's carried for me.
Some things are larger, some are smaller. The situation is the situation.
I do not feel many calibers are "puny"--they are all typically better than a sharp stick.
So, I have no reluctance to carry a round as middle-of-the-pack as 9x19.
Now, in full fairness, I'm also of an inclination that, if there's to be a firefight, I'm more inclined to want to have a Battalion Landing Team to deal with it. So, all handguns are a bit "puny" in my book, and inherently a compromise.
Life is a compromise and the situation is the situation..
