Due to arthritis of the spine and shoulders I don’t carry anything further around my waist that 3:00 position - being right handed.
Also, with the exception of pocket carry, I don’t “conceal carry” with IWB anymore.
If I were going to consider starting SOB carry, I would go with a Left handed holster carried at 6:00. This would allow me to draw “palm out” but would require much less rotation about the shoulder and little, if any, rotation of the elbow, wrist/hand.
Currently with 3:00 waist carry, can fasten seatbelt and comfortably ride in a vehicle and even sit in any chair or sofa I want without worrying about continuous pain in back.
Any specific reason you want to SOB carry? Specifically “palm in” carry? And you didn’t mention whether you preferred IWB or OWB Carry. Just curious.
