Saweet! The guns you have been shooting are certainly all fine firearms. If your first purchase is going to be an all purpose handgun that can do double duty as a carry gun and a home defense gun, gotta give the G19 and the 229 the edge, in that order, for ease of carry and reliability etc.
If your not ready to carry, you just can't beat the 226 and the 92FS for full size service pistols.
Assuming that you are talking 9mm I would say the 226 and 229 are the lightest recoil and most accurate, with the 92 being so close it is hardly worth mentioning. The only thing more reliable than a Glock 19 is the sunrise.
If you decide at some point that you would like the option of carrying, do a little research and you will find more advice than you could probably imagine on the subject. A quick tip about searching the forum is to use google. Just type "Northeast Shooters" and your question, and you will get great results.
Don't be afraid to buy a gently used handgun and save money. Lots of decent deals to be found in the NES classifieds.
As a female, you are part of the largest growing segment of lawful firearms owners... and I think it is awesome. I am so glad I got my 22 year old daughter into shooting.
