I've never seen a real outlaw biker carry a gun openly, since many are convicted felons and would be arrested for it, most of them prefer concealed carry, although I'm sure they would certainly like this.
Open carry is legal in most states, it's when you start hiding your guns that they want you to start getting permits. Probably wouldn't be too wise to get very far away from your bike when there's a real pistol in the holster if you wanted to keep your pistol, though.
Never crank or ride the bike.Judging from what I can see of this bike, it's a show bike and probably never gets ridden much at all. Probably is only ran enough to make sure it will actually start. This is a bike for someone who doesn't actually have to be worried about riding very far, if at all.However there is some dicoloration on that pipe wrap, so I'm guessing it's been ridden a little bit at least, probably colored fiberglass pipe wrap, not leather.
