Due to comfort I prefer not to OC this way. I prefer my Fobus holster outside as it allows me to move things around, especially when getting nto our out of the car. For me it is just a matter of comfort. As a bigger person, 6'5 I carry a Glock 17 which is considered a full size gun, as I don't like the feel of the smaller "compacts". I will be switching to a Sig Pro .357/.40 this weekend which is still considered a full size. I guess it depends on what you are comfortable with and the size of your gun, so to speak.
