I recently purchased a Charter Arms Undercover as a present. Unfortunately the cylinder release was sticking, so I took it apart and when I went to put it back together the detent went flying. I bought another detent and the same thing happened. I'm not trying again. Is there anyone in the central Indiana area that can put on in for me? I will gladly compensate the person for their time. I would prefer to give an INGOer some business before I ship if back to the manufacturer to attempt it. Someone has GOT to know someone.
