I may be getting ahead of myself, but as I look at where my RMR currently rides in my AIWB holster, I think that the SRO would fall at least partially below my beltline at my holster's current ride height. At first blush, I was thinking that there could be a benefit there for added concealment (at the expense of going up a waist size). As I think about it more though, if the SRO is exposed but partially under the beltline (like it would be with a traditional "RMR cutout"), would this create the potential for the pistol to be pushed out / dislodged by the belt under physical activity? Interested to see what Orionz06 and Tony Mayer think about holster designs.
