Get down to a gun store and start picking up models. You really need to find something that fits well. Especially considering you said you have small hands. My wife has small hands and the compact Storm is a bit thick in the grip for good control. She handles it well, but a bit narrower would help. I changed the back strap and it helped a bit but still not great.

Sub compacts basically are just shorter in the grip. Meaning they hold a few rounds less.

I like watching the reviews of guns on youtube. Some are good, but most are just for entertainment.

I signed up for gunbroker.com and found they have very good information.
