Obviously a quality gun belt and traditional leather or kydex holster is by far the best option to carry a pistol.
How do you EDC a decent pistol if you can't use a normal belt and holster arrangement? Think abdominal injury, hernia, surgery, medical conditions, etc..... belt pressure is no bueno.
Shoulder holsters obviously come to mind, but I won't carry a gun in a way that flags everyone around me such as a horizontal shoulder holster. External packs would be conspicuous as hell for many occasions.
Any bright ideas?
