I have small to medium hands, size 8.5 gloves, and I am a lefty. The biggest factor will be how the grip and trigger feel in your hands, after you ensure you are gripping it correctly. By far, the best small hand gripped gun in typical caliber is the S&W M&P. The CZ 75/85 is very good in fit ans size, but the DA trigger seems a bit far. The H&K was acceptable as was the Beretta 92 or any of the clones. You will find most of the 1911 style pistol grips are too large, but they can be reduced. Even though I wanted to buy one, the SIG 226 did not feel comfortable in my hand. As suggested, a G4 Glock will feel smaller as well.
You should like how it feels before you buy it. Sometimes you preference may change after firing a few hundred rounds, but each pistol has a certain feel you may like, or learn to hate. As well, depending on what you want to do with your guns, you may have to customize it or compromise on the way it feels. For instance, I didn't like how my STI open gun felt in my hands until I reduced the grip; it is much better now, but I still need to fix one issue, lowering the safety to keep my thumb on top while shooting and to reduce the pressure point the beaver tail creates on the inside of my thumb. By comparison, the CZ Shadow fit is like a custom glove.
