Absolutely none. You need to be legal to own the pistol (over 18 and no criminal history), that's all. Art 1, Sec. 13 of the Virginial Commonwealth constitution makes it clear that citizens have the RIGHT (not a privilege granted by the state) to keep and bear arms. Open carry is bearing arms. That simple. I've OC'd here for 8-10 years, and very consistently for the last 5 years and NEVER had any problem with it. The Sheriff of York County came to a few of our open carry dinners, and made it clear he will make sure his dep't always respects our carry rights.
