My EDC from day one has been the Ruger SR9c. You can pick one up for a little over $400. Double-stack, 10+1 (or 17+1 if you use the extended magazine, which also gives you a full-sized grip if you need/want one). External safety (which I only engage when I'm not carrying it), ambidextrous magazine release (useful for us lefties), and really fun to shoot. I love the trigger (especially compared to Ruger's LC series): slightly heavy, short reset. And it chews up every kind of junk ammo I've ever put through it, as well as the Hornaday Critical Defense I carry with.
