Shoulder holsters are fine for some folks...personally I don't much like them. As far as comfort and wear considerations, an OWB is probably best. There are some that can either be worn strong side (on right for right handers) or cross-draw (on left for right handed shooters). I'd go that route for flexibility reasons. There are tons of custom holster makers out there, but some get pricey and have long wait times. I'd check the Bianchi lines out or see what Midway (for example) has to offer. Good luck.
