The Right to Keep and Bear ARMS

Why do people think that the Second Amendment only applies to guns? It explicitly states "A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed." According to the dictionary, one of the definitions of the word, arms, is "weapons collectively". When the Constitution was being written, firearm technology was rather primitive. The guns of the era could only fire once before needing to be reloaded. This meant that you had to have some backup weapon available in case you either couldn't reload in time or your gun failed to fire at all. When you look at the Second Amendment correctly, it gives you the right to bear arms other than those of the firearm variety. Now obviously, some common sense must be used here. Certain weapons should only be used by trained military and/or police personnel. But I do believe that the average citizen has the right to carry a weapon for the purpose of self defense. The problem is doing so could get you in trouble with the police. Somehow I don't think quoting the Second Amendment to them will help make your case to them.
