Go back and look at the post that I was replying to, context is important.I dunno about that. Read Hal's last sentence again. If he carried open, no one would have to 'suspect' anything - it would be right there in their faces.
I'm not a proponent of off-body carry but I AM a proponent of choices. So long as your chosen method of carry assures that you will indeed carry - it's a player. BUT - whatever your chosen method is - practice, practice and then practice summore! Off-body, belly bands and ankle holsters require even MORE practice, yet, and especially including cold, first shot drills. A 2-second draw/fire capability may NOT assure your safe return home.
