Re: 1877 Colt Lightning fix, refinish, sell for parts
Someone already posted the link to Colt parts where you should be able to get all the replacement parts you need.
Then ask yourself do you want a collector gun or a safe shooter. I myself would have it refinished and rebuild it. As the cylinder is not working if your unfamiliar with how to get the timing correct have a smith do this as it is not something you wish to have done wrong.
