I am not a fan of SOB carry, but I do have one, very seldom used custom holster for caring my Glock 22 SOB. The holster is OWB, and the slide rides almost parallel to the belt; the grip is tilted only about 30 degrees up from the belt.
The article mentions most of the issues associated with SOB carry.
My favorite place to carry is about 8:00 on the belt (4:00 for you right-handed people).
