They are a bit on the chunky side. I don't carry mine (XD40SC) much these days, due to getting a DW CCO. I carried mine IWB @ 4 o'clock in a DeSantis Nylon holster. Knowing what I know now, I'd have gone a different way with the holster. I tried to do it on the cheap. Buy a good belt designed with holster use in mind and look at a Theis or a Supertuck holster. The better your carry setup, the more comfortable you will be. Oh, you might think about going up one pants size.
