before you listen to advice of anybody on this thread giving a shout out for their favorite concealment piece.... you need to mention what your needs are.
Do you have to wear your shirt tucked in? Do you wear a suit? Do you wear a belt that is either sturdy enough for a holster, or wouldn't mind getting a belt that is (ie: if you have to wear a thin, narrow, dress-belt... that's important to know). Are you thin or heavy, because if you're particularly heavy, IWB carry gets very uncomfortable fast.
Do you have a concealment method in mind? IWB, OWB, pocket, shoulder, what do you want?
Are you looking for a small gun or a full sized gun? Something inbetween? Is weight a serious concern? How big are your hands?
The easiest way to buy a gun that you will sell very quickly and take a hit on, is to buy without really knowing what you need or want. I'll bet if you want, somebody else on THR from Jacksonville will be willing to help you out a little bit when it comes to picking stuff. You would do well to take their advice over the advice of the people in the LGS. Sometimes LGS folks are great, sometimes they don't know what they're talking about.
Just as important as knowing what you want in the gun is knowing what you want for a holster. Many of us bought several holsters before finding one we liked and ended up with a box of unused holsters. It is somewhat inevitable, but figuring out what you want and what fits your needs will help you to at least avoid some of the pointless spending most of us went through. If you're lucky, patient, and prudent, you'll avoid it all.
It's not just a matter of, "I want a somewhat compact gun that I can carry OWB in a holster."
somewhat compact varies from person to person. Do you want a safety? If so, how many? Grip safety? Trigger safety? Do you want a standard hammer, or is striker fired ok? Revolver or semi-auto (bear in mind there are advantages and disadvantages to both). Do the materials matter? Steel, aluminum, hybrid alloy? Lots and lots of options here.
As for carry, OWB has lots of options. there's the standard type (I don't know what the official name is to be honest), there's cross-draw, and even then there's additional options. Paddle or belt loops? Polymer or leather? Do you want the entire gun covered or are you ok with only part of it covered. Bear in mind, here in Florida, you want to be sure you're concealing properly because accidental flashing can get you in trouble if you're unlucky enough. I'd imagine in Jacksonville that isn't as much of a problem, but it's still a consideration.
I'm not trying to scare you away from making a purchase here. The only reason I bring this up is because I too got a permit before I knew much about firearms. I still don't really know that much to be honest. Because of the fact that I knew very little, I sold the first 5 guns I bought. The last of which got sold yesterday. I also have a bunch of holsters I don't use. Now, I have a bunch of Glocks that I rotate through, and a Smith 642 as well. As for my holster, I use a couple Galco Combat Masters in different sizes for my Glocks, and a Galco horsehide pocket holster for my Smith 642. That's what works for me. I also have IWB holsters and other OWB holsters. It's crucial though that you know that this is only what worked for me. You may be entirely different with entirely different needs.
Give us an idea of what you're looking for or what parameters you're working within and we will be able to really give you some good info without just pointing out what we personally use.
If you have any questions, feel free to PM me or reply to this thread.
ETA: Congrats btw. You've taken a major step towards taking your safety into your own hands. While this is a huge responsibility, it has massive rewards. Be sure to check out this site:
http://www.floridafirearmslaw.com . There is a book sold there. Get a copy of it if you haven't already. Unfortunately, Gutmacher hasn't updated it since 2006, but it's still pretty accurate. That book is your best friend. Memorize it from cover to cover. Check that site, specifically the Book Updates section of that site to be updated on things that are no longer accurate. Best of luck to you, and hopefully we can help you get settled into the world of CCW.
