preventing exposure while carrying
I don't have a CCW, let alone a handgun (yet), but I've been considering the idea for when I do have one. I'm curious/worried about a couple things though. First thing I'm curious about...when using an IWB with an untucked closed front shirt (t-shirt), do you worry about not just printing, but exposing the butt when you squat, bend over, stretch/yawn, etc? What do you do to prevent this? Obviously you can wear an extra long shirt where this won't be a problem...but what else? Secondly, those using an OWB holster with cover (vest, un-buttoned shirt, sport-coat), do you worry about exposing the holstered gun when your covering opens, such as from a breeze, walking fast, etc? What do you do to prevent this?
Also, if for whatever reason you do expose your gun, besides merely re-covering it, do you do anything else?
