Nice looking rig! It’s the same pancake style holster that I have recently adopted and use on a daily basis for “in town” carry. Mine is produced by Simply Rugged and features a “flab guard” or what others refer to as a sweat guard, which keeps the pistol off the body, more to the point, it prevents the sights from digging into your body. I tried to like the AIWB style holsters, I have spent a fortune on them in fact in personal experimentation, and still frequently use a Philster Enigma rig with my workout clothes. For that particular purpose, I’ve found nothing better. However, after years of practice sessions and competitive shooting sporting a strong side, vertical holster, nothing else provides as natural a draw stroke, or as comfortable a carry position for me, as does the strong side setup.
