That big grip is going to be the problem. At least I've found that with service autos. If you can position it at about 2:30 with an OWB and a long shirt, you can hide the grip up around the front of your torso and under your armpit. But you need a high ride, or with a Yaqui style a long shirt. Look at the Fobus paddles just for the heck of it. Behind the hip works better for smaller guns.
