Haven't had a chance to chime in again, but for the record, little over 3yrs ago, I developed not just a sore hotspot, but also a sore and swollen lump that I self diagnosed as a possible hernia. A specialist who could not find any issues, even said the lymph nodes under the swelling were actually slightly smaller than their twins on my left side. I definitely didn't tell any medical professional that I believed the underlying issue was my all day, every single day, carry of a G19 in a kydex rig.
And fwiw I
think Gonzales said such issues, "could lead to a hernia-like injury possibly resulting in surgery." @
SouthNarc knows him, maybe he can get him to chime in.
For me, AIWB while seated, even with my lightweight .22 LCR, becomes nearly unbearable rather rapidly and can persist for days. I've got an IWB holster for my LCR en route, if it's comfy, I'll swap the kydex clip for a DCC Monoblock and lay off my AIWB for anything other than deep ccw duties.
