I don't wanta tell ya how to run your life, but you might need a new friend. First he tells you may purchase his revolver if you like, then tells you to make him an offer!?!
"Hey, Mack, you wanta sell or not? If you do, name a price. We'll talk from there."
Separately, its my understanding Charter Arms has gone through periods of poor quality. It might be smart to hit gun forums, as compared to a gun rights forum, and find out if this is maybe a gun you wouldn't want at any price.
