Bill,
Do you find AIWB not to conceal well for you? I ask because many people who can't AIWB pocket carry. That may be a natural progression to just get a smaller pistol for the pocket. But some say they can pocket carry a certain pistol but not AIWB it.
For me, pocket carry prints like I have a G19 in my pocket even if it is a small pocket pistol. What I found strange is that I can conceal AIWB without buying a larger shirt. Just my shape I guess. Tucking the shirt actually makes the grip of a G19 disappear even more. What of course doesn't work is that the thickness of the gun looks like I have a gun down my pants. What is odd is that the G43 does not. I find it odd because it really isn't that much thinner.
