I carry my Springfiled Xdm 9c in a Crossbreed SuperTuck Deluxe along with one of their belts. I love my rig and have never had any problems with it. Retention can be adjusted to your liking by simply using a hair dryer to loosen or tighten the kidex around the trigger guard.
I also have a VersaCarry clip that I've used but because the rear sites are sharp on the xdm a simple t-shirt just doesn't cut it for me. I always default back to my SuperTuck.
