We really need yet another thread on open carry?
The only problem I would see with Open Carry would be weapon retention. The average person has no training or experience with weapon retention, and most concealed carry holsters have no retention locks or thumb straps.
Sure, but does the average person actually carry a firearm? I can tell you that in the OC community, Retention style holsters are strongly recommended.
Either way, would you believe it best that the government mandate this type of thing? I don't.
