May also want to check out Blade-Tech and their product line up for IWB holsters. I've had mine since I got my XDM40 (4.5") a few years back, took a bit to get used to, but it's a great holster. Sturdy, not bulky, sits nicely on the belt line, and secures with two heavy duty straps with snap closures. Used it for my XD40 (4") also, and it was great too. I've messed around with it and put my wife's sub comp XD9 in it, and it held well also. It was around $65-$75 shipped and took a couple weeks if I remember correctly. But a great all around holster for concealed carry. I had a hybrid for my XD, and I preferred this over the hybrid. Recently I kind of added my own touch to it, I put some sandpaper on the side that is against the body and sprayed that side with truck bed liner, to reduce the chances of slipping around throughout the day while going about my business. Best of luck!
