I suppose that any of these could easily work IWB....IF you can find it comfy at 5'11" and about 185 lbs.? Wearing shirts almost always tucked in- in this climate-this might be the single factor as to whether to carry or not (?).
In a tuckable holster (theis, RKBA, cleveland, ect... all make good options) you could certainly carry it comfortably with your shirt tucked in. That said, if I was in Memphis I'd carry regardless of what I was wearing...
