I did it long ago with 3rd gen TDA S&W pistols. Then....Glock. No hammer to ride with my thumb. Switched to 3:00 carry. I tried the P30 LEMs but, I had to live and work in a Glock world. Ended up deciding on Beretta for TDA guns (Better availability of stuff, thanks to EL!) and have equipped all of my Glocks with Gadgets. So AIWB is a thing for me again. IMHO, the lessons of tilting the body in a way that prevents covering oneself while re-holstering, looking the gun into the holster, removing dangly things that foul your holster from your gear, and re-holstering slowly are universal best practices. The TDA/striker movement indicator equipped guns and quality holsters add a layer of safety to any position/mode of carry.
