I seem to bounce back and forth, but right now I am leaning more towards S&W revolvers. In handguns, I am a bit specific in my wants for most applications: S&W revolvers and 1911 autoloaders. I own a few other handgun types that are all purpose-specific firearms.
By sheer numbers, I have many more revolvers than autoloaders. I always seem to return to revolvers due to simplicity (not too many failure drills), but I sure like the trigger and flatness of the 1911.
