I have carried IWB for many years. Recently I started OWB carry, mostly for comfort reasons. My primary IWB gun was a BHP, while full size very thin. The gun I started OWB carry was a CZ P-01. This is compact gun, while a little thicker than a BHP not as thick as a Sig 229. I got a High Noon topless holster. I still want to carry concealed, and have a t-shirt w/ a untucked shirt or sweatshirt over the gun.

My observations are that carrying OWB is MUCH more comfortable. One downside is that the gun prints a little more. W/ my setup the primary reason is that the gun is not pulled as tight to the body (carrying in a 3:30 - 4:00 position) resulting in the pistol but sticking out a bit. Not the end of the world, but tighter would be nicer.
