A gun with you, no matter how small, beats a hand cannon you left at home. That being said, carry the most powerful sidearm that works well for you and that you can conceal comfortably.

I am a 1911 fan. I do not criticize my Beloved because she carries the .357 revolver that was her duty gun in her former life as a cop. I went with a Kimber Pro Carry (but would never turn down a good LW Commander), because I wanted a bit less weight that my full sized stainless steel 1911, but did not want to go shorter than 4" of barrel. Everyone must make his own decision. We're all different.

If it's comfortable for you and you're confident with it, then carry it.
