Virginia is an open carry state. However, when you open carry you draw unnecessary attention to yourself from others, to include the criminal element.
In this course understand what it means to conceal a weapon, apply self-defense and when the use of a firearm is necessary. Also, get to know where and when you can conceal carry as well as what to expect when under "survival stress".
If you have been shooting for sometime and would like to get a conceal permit, even if you don't plan to carry but have one for the home...it is a good idea to have a permit to conceal carry. Better to have it and not need it vs the alternative.
