The definition of "Open carry" in my state, is when any portion of the firearm, regardless of how small, is exposed. Years ago while deer hunting with a revolver, I was carrying my 6" 686 is a hip holster. At that time CWC was not legal. My blaze orange hunting vest was covering the top of the revolver when I was approached by a Warden. Even tho the whole holster was exposed and easily seen, the Warden informed me that I was carrying the gun concealed and thus illegal. He did not ticket me, nor really chastised me, just advised me to either make sure the vest did not cover the exposed part of the gun or to cut the tip of the holster so the muzzle of the gun was always exposed. Nowadys, with CWC being legal here and I having a permit to CWC, it wouldn't matter. Just as I would assume the scenario in the OP would not.......but, I would research the local laws to make sure there is not a stipulation similar to what JohnKSa posted.
