Kahr P9 is my favorite. Since most bad guys like dark, I have a Crimson Trace laser on it. If it's winter, a Glock #19, with laser. If summer and real hot, a Kahr .380 with laser. If my eyes were like they were when I was 30, I'd lose the laser but at my age, it helps a lot at night. I'm not particularly fleshy and don't have much to soften the outline of a weapon so size matters.
Also, I try to shot at least average of half a box of each of my carry guns every other day. Much more than a "9" and my hand gets sore. Sometimes I'll throw my Springfield .40 or one of my .38s in the mix but not regularly. Being over 60, my hands are not up to the task any more.
