Gun Choices
Assuming you are a novice shooter interested in a defensive handgun, I would recommend finding a "gun nut" friend and visit the shop/range where he or she goes. Talk to them about taking a gun safety class hosted by an "NRA CERTIFIED" instructor. They are very patient and give you the 'straight scoop' on gun safety, carry permit laws, use of force, etc., etc., and will teach you about the legal issues pertinent to carrying a firearm for protection. Obviously, the laws very signficantly from one state to another.
My personal favorite firearm is the tried-and-true .45 ACP semi-auto -- generally referred to as the "1911" by most people. I own one made by Colt (called the M1991), but other companies make them (Kimber, Taurus, Springfield, Smith & Wesson, H&k, etc, etc.) in different sizes. You can even buy a "1911" chambered in .40 caliber or even 9mm. It is rather large, though, and tough to carry concealed during warmer months. Mine holds seven in the magazine and one round in the chamber. Remember that a .45 is a very large cartridge, though, and its "fat" shape means that you don't stack 14 of them directly atop one another in a regular magazine.
A .45 semi-auto is a big pistol that sends a large slug (.230 gr) downrange with a lot of recoil, but it has excellent stopping power. The smaller 9mm (105 gr) has less recoil & is slightly more accurate than the .45 at greater range.....but it has less stopping power. Many 9mm semi-autos also offer larger magazine capacity (13 to 15 rounds in many versions).
A good compromise is the .40 S&W -- more stopping power than a 9mm, but less recoil than the .45 ACP.
My favorite revolver for concealed-carry or home defense is the Ruger LCR. It is chambered in .357 Magnum, holds just five rounds and has a very short barrel (two inches, I think). I can put it in my back pocket of a pair of jeans - but would not recommend doing so. That is just to show you its compact size. It is hammerless and thus is "double action only" - and the trigger pull is pretty hard. This is by design, though, because you do not want it to snag on something and end up with an accidental discharge! The .357 Magnum is a rare bird because it also fires .38 Special (but a .38 will not chamber a longer .357) if you want less recoil. The Ruger LCR (and other hammerless revolvers) are simple, have no "safety" switch to mess with and are point-and-shoot weapons. There is also no chance of leaving a round in the chamber because there is no chamber (as you find with a semi-auto) in a revolver. They're less likely to jam, either, and you don't have to fumble in the dark with it or worry about whether or not you remembered the magazine.
A bigger revolver might be a Taurus or a Colt Python - both in .357 Magnum. As with the Ruger, they both fire .38 Special rounds if so desired. A lot of women like the larger-frame .357 and then use .38 Special rounds for lighter recoil. A "big" gun with a big round will 'kick' a lot less than a small-frame pistol with a larger round. Think of a big V8 engine stuffed into a Mini Cooper versus a Lincoln.
To start things off, rent a .22 revolver (often nine shots) for familiarization. Ammo is cheap, the recoil is nil and you can get a good feeling for how firearms work without worrying much about the mechanics of everything. Just remember SAFETY and to always treat every gun (even a little .22) as though it is loaded.
