I've worked this problem from every angle, and have settled on an LCP with a CT laser sight. My reasoning is that a .380 might get the job done if I could get more than one round where I wanted it to go, and the laser improves the odds of that happening quite a bit.
Still, I only carry a .380 when it is simply that or nothing at all.
