Unfortunately I think everyone has that box of Holsters in the closet.I have a friend/coworker that fits those specs and he almost exclusively appendix carries, no one would ever know. I do think body type makes a big difference, but how you work around it and holster choice make just as much.
Just as you say with making your 1911 disappear, there is some combination out there that will work. Wish I knew the formula though.
