Knew there was a reason I liked you , lol.I think the instructor was referring to open carry only. I was the one who was mistaken about what he was actually referring to. My bad! I always wear a holster fastened to my belt regardless if I'm carrying concealed or open so I never really gave it much thought. This has been a good thread to sift through.
Seriously though, I have heard other instructors spout a lot of bullshit ( including what you posted yours said)so it would not surprise me at all.
