I only raised the clip just under an inch. That little bit was enough to put more of the gun under and below the belt. Now it doesn't feel like the top end can lean outwards and fall out. I probably should have attached the clip just a little bit more to the left as shown in the photo. That should help rotate the pistol clockwise looking down to help avoid the base of the magazine from sticking out. I might pick up another $11 Uncle Mike's IWB and try it again. Thanks for the recommendation!
