judging by your handle you are partial to sigs. However, if you decide to venture outside your comfort zone, you should put the Kel-Tec PF-9 on your short list. At around $280 it's very affordable. But the nicest part about it is that you won't need a holster to carry it. For $18 you can get a little metal clip that mounts on the slide. It makes for a uniquely comfortable and practical carry weapon. I added a CT laser to mine and the whole package costs me $410.
Disclaimer: This gun you shoot because you have to not because you like to. It was what George Zimmerman carried and used, although now I'm sure he wishes he'd stayed safely in his car.
