AIWB works, but I find it very uncomfortable even in a compact frame I cant imagine it even working in any full size frame.I carry a full size gun all day. All day at work. I'm not going to list the "places" I go while carrying but if I were to get caught there would be serious consequences.
AIWB is my best friend. Rarely does my midsection ever get bumped by a random person and I don't print at all.
The gun I currently am carrying is almost the length a a Glock 34.
I'm not going to carry a gun I can't effectively fight with. So it's always a full frame pistol for me unless I'm in formal clothing.
