Do you guys have any suggestions for me? Can't decide between Glock 26, 19, or some of the other models from S&W and HK? Also, where to buy online, I have used GunsLot.comand GunsBroker.com and I like them both. GunsLot.commore for the community, video, etc and GunsBroker.comfor the guns... Suggestions?

I suggest you go to nearest gun store and handle all different models/brands and see which fits you best. The gun that has best natural fit will help you shoot best. A thought is possibly move up to .40s&w.
People with smaller hands pick kahr semiautos quite often. I might also suggest para ordnance in the smaller models (my favorite brand).

Your gonna have to take her to a gun shop and see what fits her best. Para is also my favorite handguns but all that i have seen have larger grips on them because of the double stack mags and being chamberd in 45. There are many great guns out the. I will also suggest a snub nose 38 or 357 for her. She might have trouble working the slide on semi-autos.

+1!

First things first, though: why do you need the pistol? Self-defense? Plinking? Competitive target shooting? Hunting? Once you answer the why, the which become much easier to answer.

Fit is crucial. I never understood why there were so many kinds of handguns, until I realized that there were so many kinds of people. In the realm of shoes, you may love spike-heeled pumps, but I have, as yet, not found a pair that I feel comfortable in! As for pistols, I know most people swear by Glocks, but they just don't fit me well. On the other hand, most Sigs feel like they were built lovingly just for me, and many people don't care for 'em at all. So, find the one that feels great to you, and ignore the rest of us!

One caveat, however, is to use the weight of the pistol as a check & balance against the fit. A Kahr may give you a wonderful fit in your hand, but its light weight will make it less comfortable to shoot than a heavier model.

Hope this helps! And I hope the shoe analogy didn't gross you out!

Fit is important so let her pick up and feel as many models as possible. S&W make a model in pistol and revolver called a Lady Smith. They are made women's hands. A bit lighter in weight also but not as light as airwieghts.
But go with what fits and feels best to her.

Another idea is aJ frame s&w or taurus 5 shot .357 in titaninum or scaninum.
The taurus has the edge because of listing for app 1/2 the price of s&w and the fact that you can get them factory ported. The new taurus guns are way under rated I have a matching pair of .44 titatinum and they shoot great.

My wife is 5'3" and 130. She has been shooting my handguns for years, but has never been 100% comfortable with the fit and feel of most of my handguns. Before I redeployed back to Iraq the second time I took her shopping for her own handgun, as she had finished her concealed carry course. We tried many, many makes andmodels, both revolver and pistols. She wanted apistol in 40 S&W, but in the end she fell in love with a 9mm. She loves her Taurus 24/7 Pro-9BP-17 9mm. So far she has well over 1K rounds thru it, factory and reloads, and it has yet to have any failure or malfunction of any kind and itis very accurate.

Don't rule out any of the various 1911s also. They have a narrower grip than many of the doublestacks and tend to fit the human hand better than most pistols, regardless of the gender or size of the person.

Try out as many models as you can, like other said, make sure it fits you well. FWIW, a Beretta 92 (9mm) is a bit too big for her hands, but my springfield 1911a1 fits her without a problem.

Whatever you get, get some help with learning how to rack the slide. Most pistols have recoil springs of 15-20lbs or more. What works for my wife is that she grabs the back of the slide with her thumb pointed towards her body and the pistol close to the body as well, and pushes the pistol forward with the other hand.

Sounds like you have a firm idea on the cartridge; I would recommend a Heckler & Koch if you have the cash. The p2000 has 3 grip panels to adjust a fit to your hand. This is a compact German police pistol made in Oberndorf, and it works very reliably with hollow point, flat tip and full metal case ammunition. It has a 3 &1/2 inch barrel with polygonal rifling. It is also just plain fun to shoot. Nothing against Glocks; they have a different stock angle that I am not real crazy about. We could talk calibers ad infinitum but this puppy works.

What a coincidence!
I have a 9mm, and I need a 5'9'' - 125lbs lady.
Maybe we could work something out. Too funny.

Seriouslythough, it really does come down to fit.
You won't have any trouble with a 9mm as far as recoil goes, and all but the biggest double stacks should be close to the right size for your hand.

As far as a recomendation for a specific make or model goes, it completely depends on what your intended use of the gun will be. The brands you mentioned are all good, just different.

You will also need to decide on the type of action you want (SA, DA, or DAO). You will also have to make decisions about things like a having a magazine disconnect safety, the ability to execute a second strike on a misfred round, manual safety lever, mag capacity, light/laser rail, and a bunch more things.

If you are not in a rush, look at the entire field. It's full of good stuff.
