Just behind the hip bone strong side. As for the Hawaiian shirt, I can conceal my Browning HP with a tee shirt and that holster so no need to be a walking flower pot One addition, my Summer Comfort was made by El Paso Saddelry not Galco but they are similar.
Get a holster with the loops or clips spaced FAR apart from the gun and made with smooth side out leather and get ready to enjoy comfort you never thought possible.
Something like these
Summer "Comfort" is definitely not truth in advertisement.
