I think the biggest thing with IWB is getting used to the holster being inside your pants and feeling from not really right to downright painful. You have to find that sweet spot where its the most comfortable, even if at first it isnt, and where it conceals best. For me, that was either 4-4:30, ot 12:30-1:00.
Once you find that, you have to give it a little time, and get used to it. No other way to do it really. Its something you arent used to and its going to take a little time, and you need to give it that time. Youre probably going to keep making minor adjustments for a bit, and then, all of a sudden, you wont even know its there.
Holsters are holsters, and the worst part these days is, we actually have too many choices. Thats a great thing in one respect, but it can be overwhelming if you really dont know what you want. So you do the buy what you think will work and see how it goes thing.
The other problem is, just like any method of carry other than Mexican, its likely going to cost you a few bucks until you figure it out. No way around that either. Dont buy "cheap" stuff, it only ends up costing you more money in the long run, and can be dangerous as well.
Just dont mistake more expensive as always being better. A good kydex holster will cost you about half or a little more, than a good leather holster. But in the long run, it will usually be a lot cheaper, just in longevity, and problems with your gun.
You may want to consider too, if youre someone who really doesnt carry all that much, IWB may not be the choice for you. I think its really a method of carry for a more dedicated carrier, as it takes a bit more from you than OWB. If the gun isnt always there, its likely always not going to feel right the times it is, and youre probably going to just be more conscious of, and fiddly with it being there.
Theres no question, its pretty much the most concealable way to carry, short of deep concealment, but you do pay a little more for that, especially in the beginning.
These days, Im still 5' 6", and normally weigh in at 155. I carry every day, and as I said before, wear my normal clothes. In the summer here, its often in the mid to upper 90's with high humidity, I normally wear an untucked, size large, cotton tee shirt, and it easily conceals the Glock 17 I carry AIWB, with its reload and a knife. This time of year, teens to the 50's, its sweatshirts or a fleece, with a windproof for an outer garment when outside. Thats the only difference.
If you want to take things a bit deeper, a SmartCarry will allow you to easily carry something like a Glock 19, in nothing more than a pair of shorts or sweats, and no shirt. They take a bit of getting used to too, but they are also one of the most versatile holsters you'll own.
This is one of those "if theres a will, theres a way" sort of things. If you want to do it, youll figure it out. If you dont, and say you cant, youll be a prophet.
