With the few responses you have received you have the information to go forward and start you adventure.
Not knowing your expirence level I would like to make suggestion. I have a favorite that is a 1911, but also have a Glock 36 because it is easier to conceal at times. I like many others disliked the looks of the plastic gun, however they are great reliable weapons, but not one I would recommend for beginners.
My suggestion is this. When and if you go to a range to fire rentals be very honest with your level of handgun knowledge, or ask if someone there could provide you with some one on one training. I am not trying to judge you, but based on the question I feel you may be knew to handguns. My first handguns were all single action when I was younger and I still shoot them today for sport and hunting. LEO years were mostly with revolvers, I worked at a department that did not allow auto loaders, my last year there is when the change took place and things got interesting. When I started getting aquianted with the auto loaders I sure had some learnings to get under my belt.
Other than that it is fit, feel, and function. Have a great time shopping and don't get in a hurry there are allot to chose from. Did I mention my favorite is a 1911, I just love those things.
