An image of a "big moustashed" Magnum PI came to mind, although I've seen him mexican carry (no holster) that big 1911 in the small of his back on more than one occasion and go sliding into that sports car like it wasn't there, I guess when your Magnum P.I. you can do that though
Milt Sparks makes no less than fantastic holsters. My brother has the 55BN for his Kimber, upon inspection of that piece I quickly called them to work one up for my G22, it's on the way. With a long hem shirt of good thickness or a coat it's never been any problem to cover a pretty thick gun. I still want something that can go where my beretta and my 686 fear to tread, into broad daylight . . .
Beals in Flordia seem to cary many oversized aloha shirts, I'm seriously considering having my mom parcel a few up here before they come back up for the spring.
