And I think most who talk about carrying a full size gun IWB comfortably are simply full of themselves. But hey, everyone's got opinions.
The most comfortable way to carry a duty sized gun is OWB, which I have done on occasion when I'm wearing a meaty jacket for the duration. My full size gun is a 4.5" 18 +1 double stack which I have a single clip IWB holster that conceals better than anything out there. But it is not really comfortable unless you're mostly on your feet. There's not a IWB holster in the world that would make that gun completely comfortable. I had a CB holster and sent it back for a refund. It was way bulky and even more uncomfortable, and less concealable.
Smaller guns are without a doubt more comfortable to carry and easier to conceal. And for the yahoo that's going to mention it's not supposed to be comfortable but comforting, that's what extra mags are for.
As someone else mentioned a good holster makes all the difference.
This was my normal warmer months carry rig that I've recently started to carry mostly full time (LC9s w/ spare mag), mainly because it's just so much more comfortable than switching to my full size in the cold months.
It's pretty much invisible even in very light clothing but this is more "medium" cover.
I carried a LCP in a wallet holster for a while, but it made my thigh sweat.
I find a full-frame double-stack 9mm in a IWB Supertuck to be very comfortable. I'm 5'9", 180 lbs. I just don't think worrying about gun size is nearly as imperative as most new-carriers think it is. I carry a S&W 5904 most of the time. So... I guess I'm old-school.
I went through the "gun size for carry" thing in the early days. ...Just trying to save you some time and expense.
My LCP hasn't been touched in years.

How does that feel against your hip bone? One of the reasons I am thing about smaller pistols is that they will be less burdensome over the course of the day.
Y'all got me to researching holsters and I found a pretty good link in Personal Defense World.

Specifically, I liked this one.

I like that none of the gun would be in contact with my skin.
I found that a pants-pocket carried (anything) is almost impossible to access quickly while sitting in a car-seat.
Pro-tip: if you're not used to wearing a belt, any waist carry is going to get awkward.
