You looking for concealed carry? If so I highly reccomend the beretta nano. I just picked one up the other day and I love it. It's completely smooth on the outside, nothing to catch on the side, no slide release, takedown lever, or safety. The nano comes in 9mm and is 6+1. I have medium sized hands and the gun feels comfortable but I'm definately waiting for and extended mag with an extended grip. I had a Taurus 40 cal and I traded it for this one, and I believe I made the right choice.
Like most people have already said, you just have to educate yourself on the brands, their price ranges, and application. Once youve looked into that and you go look at firearms you'll be able to tell what feels right and is the best bang for your buck.
