They are a paradigm of America.
Nothing says "America at peace" any better than a revolver. The old Colt was correctly named "The Peacemaker". At one time, revolver equipped law enforcement officers were "Peace Officers", and enjoyed the respect of the people.
The revolver was and is, companion, tool and the means of providing food. Like the common American milita member, it could be pressed into service to do the job at hand, then return to it's proper place after the job had been completed.
When America girds itself for war, it turns to the common man of the street to fight it's battles. When America girds itself for trouble, it's only natural for Americans to turn to the common arm, the peacful revolver. After the war, our soldiers return to us again, as common folk. They work and live among us. Like our common soldier, the revolver, once the job at hand is complete, returns to it's former life as friend, protector, provider of food and source of enjoyment.
