I have followed this saga from all your previous posts. I would not fire one round through that gun. The forcing cone fix will still leave you with a clocked barrel which will burn your eyes every time you pick that thing up.
Selling it just dumps your misery onto someone else.
I would call S&W and get to a manager and write down his/her name. CALMLY explain all your issues before and after its return to you. Ask them if they will exchange that revolver for one that he/she, the manager, has personally inspected before shipping it to your FFL. You may get hit with a transfer fee from your FFL but you will then have the option of accepting that gun from your dealer if it is not to your satisfaction.
Saying good luck, seems like an inappropriate sign-off to you and your troubles.
