I'm the same dimensions and have no problem concealing a G30, which is thicker, or a G17 with an untucked button down or Gramicci-type shirt. If you have well developed glutes (butt), your cover garment will naturally drape out and away from the gun. Your butt will also push the gun's butt tighter into your body. These factors make concealment easier. With a flat butt, the garment is not held out as much, nor is the gun driven in close to your body. The gun might be more likely to print. You may want to try concealing the gun before you buy it but I'll bet it will conceal fine.
