This is one of those issues that shouldn't be a issue. Seriously I find it funny how much time and effort people put into this subject and to hide there gun. Unless you bend over and it gets exposed it really isn't a big deal people don't go around and go look that guy has a gun just look at that bulging hunk of gun there. Never have I heard or seen that ever. It's all paranoia on your part and if anyone says hey what's that under you shirt look at them and smile be polite as can be and say Nanya.. when they look at you with that look of what finish with Nanya ****ing business but if you really must know it's an insulin pump and walk away....
