As destructive as the concealed gun has been, it has saved man from both beast and himself. The colt revolver was a practical device that allowed individual parts to be replaced, fired multiple shots in succession (as one inaccurate bullet could not down a giant bear), and was used by law enforcement and villains alike. The principles of interchangeable parts had a huge impact as well as the revolver as a means of protecting life and liberty.
