I was looking at the same thing then I discovered the
http://www.kramerleather.com/products.cfm?categoryID=25. It has a strap on it to anchor it to the belt to insure you don't pull it off your belt during an erratic draw, which is likely the case if someone surprises you. So it slides in between the body and inside waste band, holster sits outside the waistband, the strap swivels and is easy to slide down between pants and belt then folds up to snap. Very easy putting on and taking off. I bought it specifically to carry to work then disarm so as to not lose my job
If you're carrying a full size 1911, Glock, Sig, HK, revolver it isn't the most concealable as it isn't very tight to the body. I carry a S&W 442 airweight. Basically the gun in Joel's banner graphic. With just an untucked T-Shirt for a cover garment you wouldn't be able to tell if I had a gun, cell phone, pager, or camera on my belt. You can see something’s there but it doesn't give an outline.
