Depends on the holster and your body shape, belt/clothing selection. But, generally speaking, I'd say the average decently-designed OWB/paddle holster has a better chance of being more comfortable to many folks than a similarly well-designed IWB.
Some thoughts: Fist #18 Murnak Paddle holster, for a CZ P-01 9mm.
