I like a hammer spur on a kit gun. It's easier to shoot a rattlesnake in the head with the lighter trigger in single action mode. But I carry a 642 and if I stay in practice, I can hit a snake head in DAO. Having no hammer spur is a better choice for me on a concealed carry gun.
Where in the different States Concealed Carry laws does it give the right for a private citizen to shoot at a perpetrator holding a hostage?
Most states allow for the use of deadly force to protect others in certain circumstances. Georgia, for example states: A person is justified in using threats or force to the degree they reasonably believe it is necessary to stop another person's imminent use of unlawful force. A person is justified in using deadly force which may harm or kill only if he or she reasonably believes that such force is necessary to prevent death or great bodily injury to himself or herself or a third person
or to prevent the commission of a forcible felony...
