My girlfriend carries a Springfield XD sub compact 9mm.
She does not always carry it but when she is going out or won't be home from work until later she carries it.
She uses a hip holster but it bugs her sometimes when she wants to wear a tighter shirt and can't carry and wear the shirt. I'm not positive of the brand or material , but it's not a rigid holster it's like cotton or something soft.
I carry a Springfield XD 45 ACP olive grab green.
I use an XD adjustable paddle holster on my hip. It is plastic and rotates for comfort.
If I have to lean to the side it can be uncomfortable but overall I love the gun and holster.
