Gabe Suarez is a proponent of AIWB.
Has both concealment and tactical advantages over some other types of carry positions. Grabs from behind, close encounters, headlocks,etc, you can defend the gun better.
I like it because in order to detect it, people have to scan you while you are observing them. Whereas, in rear position carry, someone might be detecting a printing without your awareness, if the pistol has slipped out of position, or you are bent over.
Draw can also be faster, since it is already close to the close ready position.
AIWB solves the problem your express with people hugging you and detecting the gun in back.
The gun in AIWB doesn't print when bending over, and you can bend back enough to make it print. You need to have a short gun, however if you wear more to 1 or 2 o'clock rather than 12 o'clock.
Main disadvantage is that it is a little more uncomfortable than 4 o'clock, and that is is more easily exposed if you are wearing a over shirt unbuttoned.
Carrying my ruger alaskan all day today AIWB for comfort test.
Friend came over today and he couldn't detect, and neither has my wife all day.
