This seems like a familiar argument!
We all know that we have permits to carry and the word concealed is not mentioned. We all also know that the majority of time we carry it is concealed. Flip never said "conceal carry permit", he asked what everyone else does when they conceal carry.
For an answer: when my weapon is IWB on my strong side, I have a double mag holster OWB on my weak side that is really easy to conceal because it doesn't ride much lower than the belt so almost any untucked shirt will hide it.
