AzCrazy;
Great suggestions by all and IMHO especially those of BBoomer. No need to repeat, but think of this as well.
See if you can find a local range that has a rental program and if so spend some time there to "TRY" before you buy.
It will save you a lot of griefe in the future and you will feel much better about your final decision.
I own a range and have been providing this service for the past 20 years and even my fellow dealers around the area send their customers over to rent and try different guns, calibers etc. see us at

I am not the brightest bulb in the socket but I have been around long enough to tell a tv from a dishwasher and I can tell you the difference between sig and Glock or sig and XD (any of the three an excellent choice) is nearly the same by comparison.
You mentioned you had/have small hands. I would be more than a little surprised if given the choice, you would therefore choose a sig over either of the other two.
In fact a person with smaller hands is not likely to pick any of the double-single action guns in my experience and that covers about an average of sales of 9 guns per day of all ages, builds/sizes and genders.
At least in the beginning and then depending upon how much, how often and which caliber you choose, your accuracy will definatly not be what you would prefer. You will shoot more accuratly out of the box with the single/"safe" action of either the glock or the xd without a doubt.
So my point is to
try a bunch before you put your money down. I am convinced you will be a much happier buyer in the end. (also, you may want to ask for an hour of time with a good instructor to go over proper grip, stance and sight picture). It will be money well spent.
Good luck and enjoy whatever your choice.
Remember also if you have a choice before you buy your first gun, you may want to buy drugs instead. I think over the years you will save a lot of money and you can always quit drugs, just look at all the movie stars who do it several times a year. But once you begin buying guns and the goodies that accompany them, you are hooked forever, you cannot quit.
I wish someone had told me that before I bought my first gun back before the middle of the last century.
