I find it hard to believe anyone is in and out of a car more than I am. I drive about a 1000 miles a week on average for work. It's actually the opposite for me. I used to carry exclusively at the 4:00 position. I had carried there for several years. I started having pains in my lower back on that side about a year ago. Come to find out it was because it was putting my back in a slight bind. Once I stopped carrying in that position my back quit hurting almost immediately.I have noticed now much more folks are moving to IWB or even AIWB lately. I guess where I struggle specifically with AIWB (while not having tried it) is in and out of the car. Figure that must be pretty close to "no cigar" using AIWB. So if one was going to go IWB and not AIWB, would you guys think 2:30 to 3:00 to maybe 3:30 to 4:00 makes the most sense, maybe with some cant particularly if 3:30 to 4:00 if you are in and out of a car?
If you will find the right holster and position for you, AIWB is great. I can actually draw very fast while seated in a car carrying that way. Drawing seated in a car from the 3-4:00 is pretty difficult. You have to lean very far forward to draw from either and there is no easy way I have found to get around the seatbelt.
I think 2:00 AIWB would be great provided your barrel/slide was very short and didn't poke you in the leg. I don't own any subcompacts. I think it would be hard to do that with anything else.
I have tried many OWB holsters. I finally gave up and decided that I just hate them. The best I have tried is a Raven Concealment. But honestly I rarely ever carry in one. Also some people talk about buying bigger pants for IWB carry. I never have, but I don't wear my pants skin tight anyway. If you carry at the 3:00 position it will at the least pull all the slack out of your pants. 4:00 seems to me to take up slightly less room in your pants. AIWB takes up no room, atleast for me. I can tighten my pants normally and still get the gun/holster in there. I think rather than pushing my pants out it's pushing my gut in.
