If your willing to try a lighter carry piece, a good paddle holster can be very comfortable and still conceal easily under a suit coat. For leather, take a look at the Kramer MSP. Kydex, look at Comp-Tac. I prefer their settable cant paddle because it rides high and a bit tight. A good paddle design can be very comfortable because it distributes the load over a wide area on the hip and reduces pull on the belt.
