In reference to the topic, I Open Carry and CC - point is, I almost always carry. Nowhere prohibited, hence the "almost."
There are times for both, when they have their purpose, but I conceal more than open. I'm not worried about OC and someone taking my pistol. What Jon said rings true - Train, Train, Train. That's more than firearms training, but it needs to be religious with the firearms, if you carry them. If you open carry, you may need more than just firearms training, depending on your area. I've been involved in martial arts since I was a young teenager, combined with some tricky military-sourced and private-funded sourced combatives since 1990. I think about someone trying to get my gun everytime I'm out - size up every single person you encounter, everytime you encounter someone. However, I'm not too worried about someone getting my gun, anytime I'm out.
