I can tell you if you follow the directions on Comp-Tacs website (even though it may not make sense), it's dead nuts on (for their kydex reinforced belt). Just do the measurement for the OWB option and add whatever they tell you to add (I think it's like 2" if I remember correctly).FireGuy4 said:Anyone have any suggestions as to where to shop for a decent gun belt other than online? I'm trying to bypass the whole "guessing what size to buy" deal. Any of the bigger retailers that you may know of??
