Call me an old conservative FUDD, but I'd never carry appendix ever.
Just something wrong with carrying in a way such that the firearm is pointed at your femoral artery when you sit down.
But what do I know?? Besides, modern guns are perfect. Its impossible for them to go off unless the trigger is squeezed.
I've been carrying since 1990. Frankly I think its a solution in search of a problem. Grow a pair and learn to carry at 4 oclock. Buy a good belt and a good holster and its more comfortable than you think. At no point in the process of putting on the holster, carrying, or taking it off, do I ever sweep myself or anyone else.
And while I'm mentioning it, the proper way to put on any holster is to put the gun in the holster first while pointed in a safe direction, then put the holster on.
