Mode of carry is very personal. Depends on body shape, clothing selection and preference. Hard to know until you've done the different modes (pocket, IWB, OWB).
OWB is nice, though, if your lifestyle and clothing can swing it. Fist Holsters makes a decent product, very durable, high value. I've got a bunch of them, for several different guns.
Having an IWB and an OWB option for a given gun is useful.
Once you've settled on a preferred mode of carry, consider getting one for the other side (ie, RH strong-side, but a second for LH draw). Useful for those times when you're stuck with a hand injury, or whatever.
If I were to do it all again, knowing what I now know, and if I had a slush fund to cover a variety of holsters just to try out several to see which I preferred, I'd probably do something like this:
Milt Sparks VM2 (IWB);
Fist #18 Murnak paddle (OWB); and, if the gun size allowed, a
Mitch Rosen Pocket Softy [aka, PSF] (pocket holster). A bit more expensive than most, but all are excellent.
