Although I don’t carry, being in CA in an unfriendly county, I do have a vertical shoulder holster for my Taurus Tracker 627. It is really comfortable if you wear a belt to connect the holster to, else the thing just gets pulled down on your weak side.
One thing I have noticed though, is that with a vertical shoulder holster, with the gun’s grip pointing straight out in front of you, you have to wear something heavy to avoid printing or looking like you have a growth in your armpit.
