A year or so ago I took a two-day class in which the instructors and most of the students were carrying AIWB. I was using a traditional leather OWB pancake, but on the second day the instructors set me up with a different gun using an AIWB holster, and something called a "wedge," with which I was unfamiliar.
I had always thought that for me AIWB was impractical, as I am overweight, specifically pot bellied. I am 6'2", and weigh about 230 (although I have been in the past as high as 265, so small victories!) I found the set up, and especially the use of the "wedge," surprisingly comfortable.
I thought I would explain a bit about it here for folks who are not familiar with the concept: The idea is to attach a wedge, typically foam cut from a yoga block or similar, thick side toward the bottom of the holster, so as to push the bottom of the holster, and the barrel of the gun, away from the body. This both makes the gun more comfortable, and safer in the sense that the gun is not pointing directly at your vitals.
Here are some photos of a wedge that I have constructed for my newly purchased Phlster Enigma Express. (The Phlster Enigma is quite a topic in itself. It's a system for carrying AIWB concealed without relying on your pants belt. It requires a fair amount of trial and error, fiddling and tweaking, to work well, but, when it works well, for many, it is a great solution. I've been trial and erroring for about two weeks now, and think I am close to having it dialed in.)



Phlster sells two sizes of wedge. I found the large too large, but the small, when I added a piece I cut from a piece of polyethylene foam, just right. Had to experiment a bit with the size of the polyethylene foam piece. I think most guys just make their own wedges. The velcro is easily cut to size, and has a sticky side so easy to attach.
