My thoughts on your gun.
Thanks for asking our advice.
However, asking someone else to pick a gun for you is like asking someone to pick a spouse for you. The best advice (that is, the most useful) is going to be in general principles rather than specific guns.
You have picked the caliber. That narrows the field. From your choice, I will infer that this is strictly for social work, not 'gators and snakes.
May I ask your reasons for ruling out revolvers? Aside from limited capacity, they are pretty good for concealed carry.
Florida? A corrosion resistant finish is a good idea. Plastic does not corrode, Stainless is very resistant, and there are several good finishes, both factory and aftermarket. Do you have any preferences yourself? I like stainless steel rather than surface applied. While stainless will corrode, and tends to pit when it does, it takes a long time to do it, and minimal cleaning will keep it just fine. I like it because I can scrub as hard as I want without worrying about wearing out a pretty finish and stainless steel will never chip off as it goes all the way through.
$1300 budget. Set aside some of that money for accessories like a good holster (and a belt to go with it - a good belt is just as important as the holster). Other accessories, too, like training and a whole lot of practice ammo (a reloading setup, but that is another post).
Some manufacturers and some models have reputations for reliability or unreliability. But even a model that has a reputation for being unreliable can be blueprinted by a good gunsmith and made reliable. After all, there are even still some Edsels still on the road. I picked up a used, VERY good condition Taurus PT145 Millenium Pro in 45 ACP that points naturally (for me), feeds everything I have tried in it, is more than adequately accurate and meets all my criteria for a good CC gun. I don't like the way it takes down, though. It only cost me $300 about 2 years ago. The point I am trying to make is that price is not the most important factor in choosing a personal defense weapon. I still prefer my stainless Colt Officer's Model.
Depending on your skill level, finger strength and personal preferences, Double action only is probably the safest for social work if you are accurate with it. The trigger pull is heavy enough that unintentional discharge is unlikely and is the same pull every time. Single action only is classic, but carrying cocked and locked makes some people nervous. A good holster is ABSOLUTELY necessary. Gen. George Patton (when he was a junior officer) nearly unmanned himself with a Colt 1911 tucked into his waistband which had the safety accidentally unlocked. Normally carried in a holster, they are safe. Then there is the Glock-style so-called "safe action" where the striker or hammer is partially cocked at all times. Study up on the choices. There are dozens of variations. For example. The Beretta 92 and the Taurus 92 are virtually identical in all their operations except the Beretta has the safety on the slide and the Taurus has the safety on the frame. I have a very strong preference for frame-mounted safeties. Entirely personal and without objective merit. It is just where my thumb believes they should be, and I am not going to argue with my thumb over the point.
Your body type may limit your choices for carry mode. Inside the waistband, in a belly band, ankle holster, shoulder holster, outside the waistband or fanny pack will indicate the size of your weapon.
How many rounds you can carry in the gun and in spare ammo. Most social encounters do not require reloading the gun, so even a single stack magazine (which is easier to wrap small hands around) usually has enough shots and a couple of spare mags (similarly flat) should be plenty. But some people like double stacks despite their more difficult concealability.
The highlights.
Finish-color, shininess, corrosion resistance
Price? I think it is pretty much irrelevant
Action type/location of controls (how much time do you have for practice?)
Size you can carry and size that fits your hand
Round count
Think about these points without regard to price or availability of guns. Once you know your desires for the perfect gun, you can buy it, or, if it does not exist, see what trade-offs you may have to make, and evaluate those trade-offs for yourself, rationally and logically.
Good luck.
