In an OC only establishment, as long as people can see the handgun in plain view I think that is all that matters. At the last VCDL gathering after our monthly January meeting one member had half his handgun showing with the barrel bottom half inside his waistband in a holster made for that type of carry. I think that met with the spirit of the law. If he was not complying I think one of the VCDL Board members would have said something to him. It looked okay to me. The law is not specific on holster type on OC, just that it has to be open carry. If it looks like you are trying to conceal it with the majority of the handgun concealed, that might be an issue. Basically if a person can see your gun, its OC.
